Go Keyless: Why Your Next Home Lock Should Be an Electronic Keyless Entry System

Go Keyless: Why Your Next Home Lock Should Be an Electronic Keyless Entry System

Most homeowners don’t think about their front door lock until a key goes missing — and by then, the question isn’t just “where is it?” but “who might have it?” A lost or unaccounted-for key is enough to compromise your entire home’s security, since standard locks offer no way to track duplicates or revoke access. Electronic keyless entry systems close that gap entirely. In this guide, you’ll learn how these systems work, which type fits your home, and why the installation process matters just as much as the product you choose.

What Are Keyless Entry Systems?

A keyless entry system is an electronic lock that authenticates the person — not a physical key. Access is granted through a PIN code, fingerprint scan, smartphone app, or RFID fob, depending on the model. Most residential units are designed to fit a standard deadbolt backset, so they integrate with existing doors without structural modifications.

Unlike a traditional lock-and-key setup, these systems let you create and revoke credentials without calling a residential locksmith for a rekey. Change a code in seconds. Add a temporary PIN for a contractor. Delete access when someone moves out. The control stays with you.

Why Standard Deadbolts Leave Gaps in Your Home Safety

A traditional deadbolt provides solid resistance to brute-force entry — but it has vulnerabilities that go unnoticed until they’re exploited:

  • Untracked duplication: Any hardware store can copy a house key in minutes. You have no way of knowing how many copies exist or who has them.
  • Lock bumping: A specially cut “bump key” can manipulate the standard pin-tumbler mechanism in most residential deadbolts, a technique documented extensively by security researchers at organizations like the American National Standards Institute (ANSI).
  • Thumbturn lock exposure: Interior-facing thumbturn locks can be turned from outside if an intruder breaks a glass panel adjacent to the door — a risk that keyless systems with no thumbturn exposure eliminate.
  • Zero access history: Standard locks offer no log. You have no record of who entered or when.

Electronic keyless entry systems address every one of these points at the hardware level.

4 Types of Keyless Entry Systems for Homes

1. Keypad Deadbolts

The most accessible entry into keyless security. A numeric keypad replaces the traditional cylinder. Set a personal code for your household, a separate temporary code for guests or service workers, and delete it when it’s no longer needed. These work entirely offline — no Wi-Fi, no app, no dependency on a phone.

2. Smart Locks with App Control

These connect via Bluetooth or Wi-Fi and pair with a smartphone app. Lock or unlock your door from anywhere, receive entry alerts, and manage access codes remotely. Popular brands like Schlage, Yale, and August integrate with Google Home and Amazon Alexa for voice control.

3. Biometric Fingerprint Locks

Fingerprint scanners store individual prints and grant access in under a second. There’s no code to share, no fob to lose — access is literally on your hand. High-end models store up to 100 fingerprints, making them practical for households with multiple family members.

4. RFID / Key Fob Proximity Locks

A programmed card or fob held near the reader unlocks the door. Common in commercial applications, these are gaining traction in residential settings, especially as part of a broader high-security lock setup that combines multiple access layers.

Deadbolt Security Grades: What the ANSI Rating Actually Means

ANSI classifies residential locks into three grades. Grade 1 is the highest — engineered to withstand over 250,000 open/close cycles and kick-in forces exceeding 250 lbs. Most quality smart locks are built on a Grade 1 or Grade 2 deadbolt frame, meaning the electronic component rides on a mechanically sound foundation.

That said, a Grade 1 lock installed on a weak door frame still fails. When a professional locksmith from CallOrange installs your system in Tempe, Mesa, or Chandler, the assessment always includes the door frame and strike plate — not just the lock itself.

Pro Tip: The Strike Plate Is the Most Overlooked Part of Any Lock Installation

After installing keyless systems across Tempe and the East Valley, the most consistent finding is this: most builder-grade homes ship with a 2-inch strike plate held by half-inch screws that bite into the door jamb alone. A well-placed kick bypasses even the strongest deadbolt in that scenario.

The fix is simple: replace it with a 6-inch reinforced strike plate using 3-inch screws that anchor into the structural stud behind the jamb. This single upgrade dramatically increases door-kick resistance — no new lock required. When you pair it with a quality keyless deadbolt, you’ve addressed two of the most common residential entry points at once.

Before You Buy: 5 Home Safety Checks for Keyless Lock Installation

  1. Door frame integrity — Inspect for rot, previous damage, or gaps around the latch area before installing any lock.
  2. Door thickness — Most smart locks fit doors 1-3/8″ to 1-3/4″ thick. Confirm your door’s measurement before ordering.
  3. Wi-Fi signal strength at the door — App-controlled locks require a stable signal. A weak connection causes intermittent failures.
  4. Existing lock condition — If your current deadbolt is worn or misaligned, start with a lock change before adding electronics on top of a failing mechanism.
  5. Backup access plan — Every keyless lock should have a secondary entry method: a physical key override slot, a backup code, or a mechanical bypass kept in a secure location.

Do You Still Need a Traditional Deadbolt Alongside a Keyless Lock?

In most cases, no — because keyless entry systems are deadbolts. The locking bolt mechanism is identical; only the access method changes. Some retrofit smart locks slide over your existing deadbolt cylinder, preserving the mechanical bolt while adding electronic control. Others fully replace the cylinder.

If your existing lock is still structurally sound, a lock rekey followed by a smart retrofit may be the most cost-effective path. If the hardware is worn or outdated, a full lock replacement sets a cleaner foundation.

Schedule a Keyless Lock Installation or Home Security Audit in Tempe

Switching to a keyless entry system is one of the most practical home safety upgrades available — but the product is only as good as the installation behind it. Misaligned bolts, incorrect backset sizing, and skipped strike plate reinforcement are all common errors in DIY setups that compromise the security you paid for.

The team at CallOrange Locksmith Tempe has been installing and servicing residential locks across Tempe, Mesa, Chandler, Scottsdale, and Phoenix since 2008. We’ll assess your door, recommend the right system, and complete the installation correctly the first time.

Frequently Asked Questions

Are keyless entry systems safe against hacking or code theft?
Quality keyless entry systems use AES-128 or AES-256 encryption for wireless communication, making remote interception impractical for standard residential attacks. Rolling code technology changes the authentication signal with every use, so a captured signal can’t be replayed. The greater vulnerability is usually a weak or reused PIN code — not the hardware itself. A residential locksmith can advise on best practices for code management and layered security.
What happens if the battery dies on a keyless lock?
Nearly all residential keyless locks include a low-battery warning — typically an audible alert or flashing indicator — well before power fails completely. Most models also have a physical key override cylinder as a backup. A select few higher-end units include an emergency terminal on the exterior that accepts a 9V battery for one more code entry. Replacing the batteries once or twice a year prevents the situation entirely.
Can a keyless entry lock be installed on any residential door?
Most standard keyless locks fit doors between 1-3/8″ and 1-3/4″ thick with a standard 2-1/8″ bore hole — covering the vast majority of residential exterior doors. Doors outside those dimensions may require adapters or a different product line. A professional locksmith will verify these specs during a site visit to avoid compatibility issues at installation.
Do keyless entry systems require Wi-Fi to function?
No — only smart locks with app control require a Wi-Fi or Bluetooth connection. Keypad deadbolts, biometric locks, and RFID systems operate entirely offline with no network dependency. Smart locks also function locally when the internet is down; you simply lose the remote-access feature until connectivity is restored.
Is it better to install a keyless lock myself or hire a professional locksmith?
Simple keypad deadbolts are designed for DIY installation on a properly prepared door. However, professional installation ensures correct bolt alignment, door frame integrity assessment, and proper programming. For biometric, RFID, or smart locks with wiring components, professional installation is the recommended path. See our lock change service for what a professional installation includes.
Can I keep my existing deadbolt and just add a keyless entry system?
Yes — retrofit smart locks attach to the interior side of your existing deadbolt and motorize the thumbturn, so your exterior hardware stays the same while you gain electronic control. If the existing deadbolt is worn or low-grade, a full lock replacement first is recommended for the strongest foundation.

Stop Lock Bumping: How to Upgrade Your Home’s Vulnerable Entryways

Stop Lock Bumping: How to Upgrade Your Home’s Vulnerable Entryways for Real Lock Bumping Protection

Lock bumping is a low-tech break-in method that opens standard pin tumbler deadbolts in seconds using only a modified key and a blunt object — no drilling, no forced entry, and no visible damage left behind.

Most homeowners assume a deadbolt means safety. The reality: a technique called lock bumping renders the majority of standard residential locks open in a single strike, and most people never know it happened until valuables are already gone. The fix isn’t complicated — but it requires knowing which hardware actually holds up and when to bring in a professional locksmith for a full residential security review. In this guide, you’ll find exactly what to look for, which upgrades deliver genuine protection, and how to build real lock bumping protection at every entryway in your home.

What Is Lock Bumping and Why Does It Threaten Home Safety?

Lock bumping exploits a fundamental flaw in the pin tumbler mechanism — the internal design found in virtually every standard residential deadbolt on the market. A bump key is a specially cut key modified so each cut reaches the maximum depth allowed by the keyway. The key is inserted into the target lock, and when struck sharply with a mallet or blunt object, the kinetic energy causes all driver pins to jump simultaneously. For a fraction of a second, the pins clear the shear line and the cylinder turns freely.

The entire process takes under thirty seconds. It leaves no scratches on the keyway, no damaged frame, and no evidence of forced entry. On insurance claims and police reports, it often registers as an unexplained entry. According to ALOA (Associated Locksmiths of America), bump keys can be manufactured from standard key blanks and have been extensively documented in security research since the early 2000s.

Is Your Current Deadbolt at Risk?

If your deadbolt carries a standard ANSI/BHMA Grade 2 or Grade 3 rating and uses a conventional pin tumbler cylinder, it’s likely vulnerable. This covers the majority of builder-grade locks installed in rental properties and tract homes across Tempe, Mesa, Chandler, Scottsdale, and the broader East Valley.

Signs your current hardware may not be delivering adequate home safety:

  • The lock was installed by the original builder or left behind by a previous occupant
  • No “bump-resistant” or “high-security” designation appears on the packaging
  • The cylinder uses a standard 5- or 6-pin configuration without secondary anti-bump features

If you’re unsure what’s installed at your entries, a residential security assessment from our team can identify every vulnerability before it becomes an entry point for an intruder.

Lock Bumping Protection: The Deadbolts and Hardware That Actually Hold Up

Bump-Resistant vs. Bump-Proof — Know the Difference

There’s a meaningful distinction between these two terms. Bump-resistant locks use modified pin chambers or secondary locking elements that raise the difficulty of a successful bump attempt — but they are not impervious with enough persistence. Bump-proof locks eliminate the pin tumbler mechanism entirely:

  • Disc detainer locks — use rotating discs instead of driver pins. No bump key geometry can exploit this mechanism.
  • Sidebar locks (e.g., Medeco Maxum, Mul-T-Lock MT5+) — require both a rotational and a lateral movement to turn the cylinder, making them mechanically resistant to both bumping and picking.
  • Dimple locks — use a different keyway orientation that standard bump keys cannot target.

For whole-home deadbolt security, look for locks carrying an ANSI/BHMA Grade 1 rating with documented anti-bump, anti-pick, and anti-drill certifications. Our licensed technicians handle deadbolt upgrades and full lock changes for residential clients throughout Tempe and the East Valley.

The Thumbturn Lock: How It Fits Into Your Defense

A thumbturn lock — the interior rotating knob on a single-cylinder deadbolt — doesn’t directly resist a bump entry from outside. However, its configuration matters in composite attack scenarios. Doors with decorative glass panels are especially vulnerable: a bump entry is followed by a hand reaching through shattered glass to turn the interior thumbturn. For those specific openings, a double-cylinder deadbolt requiring a key on both sides is worth serious consideration. For standard solid wood or fiberglass doors, a quality single-cylinder thumbturn paired with a certified Grade 1 deadbolt delivers solid protection.

🔐 Pro Tip — From the Field

In servicing locks throughout Tempe and the East Valley, the single most overlooked upgrade is the strike plate. A standard builder-grade strike plate uses 3/4-inch screws driven into soft wood framing — it offers almost no resistance to a coordinated kick. Replacing it with a reinforced steel strike plate secured with 3-inch screws into the door stud — at the same time as the deadbolt upgrade — closes both the bump vulnerability and the kick-in vulnerability in one visit. Address them together or you’ve only solved half the problem.

Home Safety Goes Beyond the Cylinder

Upgrading the cylinder is step one. A layered home safety strategy closes the remaining gaps that a new deadbolt alone cannot address:

  • Door reinforcement kits — door jamb armor and hinge reinforcers protect against kick-in attacks that can defeat even a bump-proof lock if the frame gives way first
  • Smart locks with tamper alerts — models with app-based tamper notifications add a detection layer, even when the underlying cylinder remains a pin tumbler design
  • Entry-point cameras — visible surveillance deters opportunistic bump attempts before they start
  • Rekeying after every occupancy change — a professional lock rekey ensures no copied keys from former tenants or contractors remain in circulation

For commercial and multi-tenant properties, the same principles scale up. Commercial locksmith services address high-security cylinder replacements for mortise lock bodies, cylindrical commercial hardware, and access control integration at high-traffic entries.

Frequently Asked Questions — Lock Bumping Protection

Common questions from homeowners in Tempe, Mesa, Chandler, and the East Valley.

?

What exactly is lock bumping and how does it work?

Lock bumping is a non-destructive entry technique that exploits the pin tumbler mechanism inside most standard deadbolts. An attacker inserts a specially cut bump key into the keyway and strikes it sharply. The impact causes all the driver pins to jump simultaneously, momentarily clearing the shear line and allowing the cylinder to turn. The process leaves no visible damage, making it difficult to detect on a police report or insurance claim.

?

How do I know if my current deadbolt is vulnerable to bumping?

If your deadbolt is a standard pin tumbler model rated ANSI/BHMA Grade 2 or Grade 3 — which covers the vast majority of builder-grade hardware — it’s likely vulnerable. Look at the lock packaging or the lock body itself. If you don’t see designations like “bump-resistant,” “high-security,” or an ANSI Grade 1 rating with additional certifications, assume the lock can be bumped. A licensed locksmith can assess every entry in your home and give you a clear picture of where you stand.

?

What are the best locks for lock bumping protection?

Locks that eliminate the pin tumbler mechanism entirely provide the strongest protection. Disc detainer locks (like the Abloy Protec2) and sidebar locks (like the Medeco Maxum or Mul-T-Lock MT5+) are considered bump-proof by design. For homeowners looking for a strong upgrade without going to the highest tier, ANSI Grade 1 deadbolts with documented anti-bump certifications offer a meaningful improvement over standard builder hardware. Have a professional locksmith assess your specific doors before selecting a model.

?

What is a thumbturn lock and does it affect bump resistance?

A thumbturn lock is the interior rotating knob on a single-cylinder deadbolt — the part you turn from the inside without a key. It doesn’t directly affect how resistant the lock is to bumping from outside. However, its design becomes relevant for doors with glass panels. On those doors, a break-in may combine a bump entry with a reach-through to turn the interior thumbturn. For glass-panel doors, a double-cylinder deadbolt — requiring a key on both sides — removes that secondary vulnerability entirely.

?

Can a smart lock be bumped the same way?

It depends on the model. Many smart locks still use a traditional pin tumbler cylinder as a physical backup, which means they remain vulnerable to bumping despite the electronic access component. Smart locks that rely exclusively on electronic or motorized mechanisms — with no physical keyway at all — are immune to bump attacks. If you use a smart lock with a physical key backup, check the cylinder grade and verify it carries anti-bump certification.

?

Do I need a professional locksmith to upgrade my locks, or can I do it myself?

High-security locks — particularly sidebar and disc detainer models — require precise installation to function correctly. An improperly installed bump-proof lock can fail to engage fully, defeating its purpose entirely. Beyond the cylinder itself, a professional locksmith inspects the strike plate, checks door alignment, and assesses the entire entry. For standard Grade 1 deadbolt upgrades, a competent DIYer can manage installation, but a security audit from a licensed locksmith identifies vulnerabilities a product swap alone won’t solve.
