Changing locks on an apartment typically costs $80-$250 for one standard lock when a locksmith supplies and installs new hardware; rekeying is often $75-$150 for one lock, including a service call. The final price depends on the lock type, number of cylinders, labor, location, and whether the work is urgent or requires landlord approval.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Rekey one lock | $50 | $100 | $175 | Often includes a service-call fee |
| Replace one standard lock | $80 | $150 | $250 | Basic deadbolt or knob lock |
| Replace with a smart lock | $150 | $275 | $450 | Hardware, setup, and installation vary |
| After-hours locksmith visit | $125 | $225 | $400 | Urgency and local rates affect the total |
What does changing one apartment lock usually cost?
A locksmith commonly charges $80-$250 to remove and replace one standard apartment lock, with a typical job landing near $150. This assumes one exterior door, a basic keyed deadbolt or entry knob, ordinary access, and no door repair. A tenant who only needs the existing lock rekeyed may pay less because the hardware stays in place.
Prices rise when a door has multiple keyed cylinders, a high-security lock, a restricted key system, or a smart lock. Replacing a deadbolt and knob together can cost roughly $150-$350 installed. Assumptions: standard U.S. apartment entry door, weekday service, basic hardware, and normal access. For a single standard lock, budgeting $100-$200 covers many routine locksmith visits.
Which locksmith charges appear on an apartment quote?
Ask whether the estimate includes the visit, hardware, installation, and old-lock disposal. Some locksmiths quote a low labor rate but add a separate service-call fee. A written quote should identify the number of locks and whether matching keys or extra keys are included.
| Quote component | Typical price | What changes the charge |
|---|---|---|
| Service call | $50-$100 per visit | Distance, minimum charge, or time of day |
| Labor | $40-$90 per lock | Lock complexity and installation time |
| Basic lock hardware | $25-$100 per lock | Brand, grade, and deadbolt versus knob |
| Key copies | $2-$10 each | Key type and quantity |
| Smart-lock hardware | $100-$300 per unit | Features, connectivity, and brand |
Labor for a routine lock change often takes 30-60 minutes. More than one lock may increase labor but can reduce the per-lock cost if the locksmith can do the work during one visit. Compare the all-in price, not just the advertised hourly rate.
How lock type and door condition shift the price
A basic cylindrical lock is usually the least expensive option. A deadbolt with a higher security grade, a restricted keyway, or a compatible master-key system may cost more because of the hardware and key-control requirements. Smart locks can add $100-$300 for the device alone, before installation or setup.
Door and frame condition also matter. A locksmith may charge extra if the bolt does not align, the existing holes are nonstandard, or the door needs drilling or reinforcement. For example, correcting a simple alignment issue may add $25-$75; more substantial carpentry or frame work can cost $100 or more. A lock that fits the existing door preparation is usually cheaper to replace.
When is rekeying cheaper than replacing apartment locks?
Rekeying changes the lock cylinder so old keys no longer work, while keeping the existing hardware. It often costs $20-$50 per cylinder plus a $50-$100 service call. That can make it a lower-cost choice when the lock is in good condition and the tenant or property owner only needs to invalidate old keys.
Replacement makes more sense when a lock is damaged, difficult to operate, outdated, or incompatible with the desired key system. A new lock also provides an opportunity to upgrade hardware, but the added cost may not be necessary after a routine move if the current lock is functional. Before paying for either option, confirm who is authorized to approve the work and who is responsible for the bill.
How long do apartment lock changes take?
A simple rekey or standard replacement generally takes 30-60 minutes per door once the locksmith arrives. Installing a smart lock, changing several locks, or adjusting a door can take one to two hours. The visit may take longer if the cylinder is seized, the key is broken, or the locksmith must identify an unusual lock system.
Labor pricing often works out to about $40-$90 per lock, but many providers charge a minimum visit fee instead of billing a precise hourly amount. Emergency or late-night appointments can add $50-$150 or more to the bill. Scheduling a weekday appointment can avoid many after-hours surcharges.
Three apartment lock quotes and what they include
These examples illustrate how scope changes the total; local rates and hardware selection can move quotes outside the ranges shown.
| Apartment job | Estimated total | Pricing details |
|---|---|---|
| Rekey one standard deadbolt | $75-$150 | $20-$50 cylinder work plus service call and one key |
| Replace deadbolt and knob | $160-$325 | Two basic locks, 1-2 labor hours, ordinary access |
| Install one smart deadbolt after hours | $250-$500 | $150-$300 device, setup, labor, and possible rush fee |
A quote should state whether tax, extra keys, removal, and any door adjustments are included. Ask whether the provider charges a separate trip fee if the lock does not fit. For apples-to-apples comparison, request the same lock grade and scope from each locksmith.
Do apartment rules or local codes affect lock replacement?
Tenants should check the lease and contact the property manager before changing an exterior lock. Rules differ by lease and jurisdiction, and landlords may need access for emergencies or maintenance. A building may require a specific key system, restrict smart locks, or require the manager to hold a copy of the key.
Replacing a lock does not usually require a building permit, but local fire and egress requirements can affect hardware on doors used for exit. Avoid installing a lock that prevents occupants from exiting without a key. If the change is related to a safety concern, document the request and ask the landlord about an authorized rekey or replacement. Getting approval first can prevent a second locksmith visit and avoid lease disputes.
How to reduce the price of changing apartment locks
Check whether rekeying will solve the problem before buying new hardware. If several locks need attention, arrange them for one appointment and ask whether the service-call charge is shared across the work. Provide clear photos of the lock and door edge when requesting estimates; this can help identify the hardware and reduce surprises on arrival.
Compare at least two written quotes that list the visit fee, labor, hardware, and key copies separately. Choose a standard lock that fits the existing holes rather than paying for unnecessary drilling or premium features. Avoid emergency service when the door is secure and the work can wait; if a lock is broken or access is compromised, tell the locksmith exactly what has happened before authorizing work. Controlling the scope and timing often saves more than choosing the cheapest lock available.
