Rekeying and lock replacement are two different solutions to two different problems — and choosing the wrong one costs either money you didn’t need to spend or security you can’t recover. Rekeying reconfigures the pins inside the existing cylinder so the old key stops working and a new key takes its place. Lock replacement swaps the entire hardware unit. The right choice depends on the condition of the hardware, the reason you need the change, and what level of security you want going forward.
The most common reason Tempe homeowners call about rekeying is a life transition: a move into a new home, a roommate or tenant moving out, a relationship ending, or a key that was lost or stolen. In every one of those scenarios, the question isn’t whether the lock works — it’s whether the wrong person might still have a key that works. That’s a rekeying situation, not a hardware replacement situation, unless the lock itself is damaged or you want to upgrade security at the same time.

What Rekeying Actually Does — and What It Doesn’t
Rekeying changes which key operates the lock. It does not change the lock itself.
Inside every pin tumbler cylinder is a stack of driver pins and key pins — typically five or six pin stacks depending on the keyway. The key lifts each stack to a precise height determined by its cuts. When all stacks align at the shear line, the cylinder turns. Rekeying replaces the key pins at the bottom of each stack with pins of different heights, calibrated to a new key blank. The old key’s cuts no longer align the stacks. The new key does.
The entire process takes 15–20 minutes per lock. The cylinder is removed from the door hardware, the retaining clip is released, the plug is pushed out, and the pin stacks are swapped using a plug follower and pinning tray. The cylinder goes back in, the new key is tested, and the job is done. The existing lock hardware — the deadbolt body, the latch assembly, the strike plate, the door prep — stays exactly where it is. Nothing on the door changes except which key turns it.
What rekeying doesn’t do: it doesn’t upgrade the pick resistance of the cylinder, doesn’t change the bump resistance of the lock, and doesn’t address physical damage to the hardware. If the deadbolt throw is short, the strike plate is loose, or the cylinder has wear from years of use, rekeying fixes the key control problem but leaves every other vulnerability in place. That’s the distinction that determines when a full lock change is worth the additional cost.
Our lock rekey service covers all standard residential pin tumbler cylinders, including deadbolts and knob/lever sets.
What a Lock Change Involves — and When It’s the Right Answer
A lock change replaces the entire hardware unit: deadbolt body, cylinder, latch or bolt mechanism, and exterior and interior trim. The door prep — the holes drilled for the lock and the latch — stays the same if the new hardware matches the existing bore dimensions. Most residential deadbolts use a standard 2-1/8″ bore, which covers the vast majority of replacement options at every price point.
Lock replacement is the right answer in four specific scenarios:
The hardware is physically damaged. A cylinder that’s been drilled, a deadbolt body that’s been forced, a latch that’s seized or misaligned — damaged components don’t rekey correctly and can fail under normal use. Replacement is the only reliable fix.
The lock is worn to the point of functional unreliability. Tempe’s dust and heat accelerate cylinder wear faster than in moderate climates. Fine particulate from desert conditions works into the keyway and acts as an abrasive on the pin stacks. A cylinder that’s been through a decade of Tempe summers without lubrication may have tolerances too loose for accurate rekeying. A new cylinder performs to factory specification.
You want a security upgrade at the same time. Rekeying a builder-grade Kwikset to a new key does nothing for its pick resistance or bump resistance. If you’re rekeying after a security concern — a break-in attempt, a lost key in a high-risk situation — upgrading to a high-security cylinder like a Schlage Primus, Medeco, or Mul-T-Lock at the same time addresses the key control problem and the hardware vulnerability in one visit. Our high-security locks service covers what distinguishes a high-security cylinder from a standard residential lock.
You’re replacing a deadbolt with a smart lock. Smart lock installation is a lock change by definition — the entire hardware platform changes. The cylinder is replaced with an electronic module, and the interior assembly changes entirely. Our lock change service covers standard replacement, and for smart lock conversions, we address the door prep if the new hardware requires it.
The Cost Difference — What You’re Actually Paying For
Rekeying costs less than lock replacement in almost every scenario. The cost of a rekey is labor plus a minimal parts cost — a set of key pins and a new key blank. The lock hardware itself is untouched.
Lock replacement costs more because you’re paying for new hardware in addition to labor. The hardware cost varies widely: a builder-grade Kwikset deadbolt runs $20–$40. A mid-grade Schlage B60N runs $40–$70. A high-security Schlage Primus or Medeco cylinder runs $150–$300 for the cylinder alone. The labor to install any of them is roughly the same.
The scenario where lock replacement actually saves money: If you’re moving into a Tempe home and the existing locks are worn builder-grade hardware from 2005, rekeying them gives you key control but leaves aging hardware on the door. Replacing them with mid-grade deadbolts gives you key control, new hardware tolerances, and a warranty — for a cost difference that’s modest when you’re already paying for a locksmith visit.
We give you the honest comparison on-site. A written quote covers both options when they apply, and you decide which direction matches your situation and budget. There’s no pressure toward the higher-cost option — our job is to solve your security problem, not to sell hardware you don’t need.
Tempe-Specific Factors That Affect This Decision
Arizona’s climate creates two residential lock issues that don’t come up in the same way in moderate markets.
Cylinder wear from dust. The fine particulate common in Tempe’s air — particularly during haboob season — works into keyways and pin chambers over time. A well-maintained cylinder with periodic lubrication handles this without issue. A cylinder that’s been running dry for years may have pin stack tolerances loose enough that rekeying produces an unreliable result. When we assess a cylinder before rekeying, we’re looking for this wear pattern.
UV and heat damage to rubber gaskets and plastic components. Exterior lock hardware in Tempe takes UV and thermal stress that interior hardware doesn’t. Rubber gaskets around the cylinder and interior the deadbolt body degrade and crack. On some older hardware, the plastic cam at the back of the cylinder becomes brittle. Neither of these is visible from the outside, and neither prevents rekeying — but both are signs that the hardware has more years behind it than ahead of it, which factors into the rekey-vs-replace recommendation.
When we assess your locks in Tempe, we account for both. The recommendation you get reflects the actual condition of your specific hardware, not a default preference for one service over the other.
| Situation | Recommended Service | Why |
|---|---|---|
| Moved into a new home in Tempe | Rekey (or replace if hardware is worn) | Previous owner, agent, and contractor keys all stop working — same hardware, new key control |
| Lost or stolen key | Rekey immediately | Lost key is no longer valid — hardware condition permitting, no replacement needed |
| Tenant or roommate moved out | Rekey | Key access revoked without hardware replacement — faster and lower cost than new locks |
| Lock physically damaged or forced | Lock replacement | Damaged hardware can’t be rekeyed reliably — replacement restores full function |
| Hardware is worn — builder-grade 10+ years old | Lock replacement | Loose pin tolerances from Tempe dust wear make rekeying unreliable — new hardware performs to spec |
| Want pick or bump resistance upgrade | Lock replacement — high-security cylinder | Rekeying doesn’t change cylinder security rating — only new hardware upgrades resistance |
| Multiple doors — want one key for all | Rekey to matching key or master key system | All compatible cylinders rekeyed to same bitting — one key operates all doors |
Master Keying and Key Consolidation — A Third Option Worth Knowing
If you’re a Tempe homeowner or landlord managing multiple units or entry points, rekeying also opens the option of master key consolidation — configuring multiple cylinders to operate on a single master key while each lock still has its own individual key. This is accomplished through a bitting hierarchy in the pin stacks that creates two shear lines: one for the individual key, one for the master.
Master keying is more complex than standard rekeying and requires planning the key hierarchy before any pins are cut — you can’t add master keying to an existing standard rekey after the fact without redoing the job. If key consolidation is relevant to your situation, tell us when you call and we’ll plan the pinning accordingly.
For rental properties where tenants need individual key control and the owner needs master access, this is a standard approach that eliminates the need to replace hardware every time a tenant turns over. Our lock rekey service and lock change service both support master key configurations.

Making the Right Call
Most Tempe homeowners who need to change who has access to their home need a rekey — not new hardware. The lock works fine; the problem is that someone else has a key that also works fine. Rekeying solves that in 15–20 minutes per lock at a fraction of the cost of new hardware.
Lock replacement is the right call when the hardware itself is the issue: physical damage, excessive wear, a security upgrade, or a smart lock conversion. We assess your existing hardware on-site and tell you which situation you’re actually in before quoting either option.
