Rekeying vs. Replacing Locks: Which Option Is Best for Your Home?

A practical move-in checklist and a clear comparison of rekeying, repair and replacement.

Updated October 26, 2026

Start with condition and access control

Rekeying is worth discussing when a compatible lock works properly and your goal is to stop an old key from operating it. Replacement may be more appropriate when hardware is damaged, unreliable or lacks the features you need. A door or frame problem can need attention whichever option you choose.

What rekeying changes

Rekeying changes the cylinder keying so a different key operates that cylinder. Suitable external hardware can stay in place. It does not automatically repair wear, strengthen a door frame, change electronic access codes or alter locks that were not included in the work.

What replacement changes

Replacement changes the specified hardware, such as a cylinder, deadbolt or lockset. Confirm exactly which parts are included. Ask how the proposed product fits the door and how it addresses the problem; a new finish alone is different from repairing unreliable operation.

Compare the decisions

Situation	Discuss first	Check before choosing
Working lock; old key should stop working	Rekeying	Cylinder compatibility and condition.
Damaged or unreliable hardware	Repair or replacement	Door, frame and alignment as well as the lock.
Different access features wanted	Compatible replacement	Fit, operation and credential management.
Several doors should share a key	Keyed-alike options	Compatible keyways and authorization for every door.

How professional rekeying is assessed

The technician identifies the lock and checks its condition and compatibility before changing its keying. Explain any sticking, rough operation or missing keys. The exact work depends on the product. Use the model information from Kwikset, Schlage, Yale or Master Lock when identifying your hardware.

How replacement is assessed

Replacement planning should account for the door, existing preparation, alignment, hardware fit and intended use. Describe the symptoms before selecting a product. Our residential service can discuss the lock and door condition rather than assuming a new cylinder resolves every problem.

What to include in the cost comparison

Count the cylinders or doors and state which work you need on each. Ask about labor, parts, the number of supplied keys and applicable visit or timing charges. Compare those same items in each estimate. Review our published pricing guide, then confirm the scope for your appointment.

Is rekeying always cheaper?

No universal price comparison applies to every job. Retaining suitable hardware avoids buying that replacement hardware, but condition, compatibility, the number of locks and the complete work affect the estimate. Ask for the relevant options to be explained instead of choosing on a headline starting price.

When changing a working lock’s keying may help

Consider an access review after a move, an unreturned key or a change of authorized users. Identify all affected cylinders, including secondary doors. If you rent, manage a property or share an access system, confirm your authority and any required coordination before work is arranged.

When repair or replacement needs attention

A cracked, forced, loose or unreliable lock needs an assessment of its condition. Rekeying alone does not cure every mechanical issue. If the bolt binds, the door shifts or the strike area is damaged, explain those symptoms. For urgent access problems, call our emergency service to check availability.

Retail counter or mobile visit?

If you are considering a store counter service, check the local provider’s current availability, supported model and whether hardware must be brought in. Compare that arrangement with an on-site visit and assessment. Do not assume every location or every lock is supported.

Can every lock be rekeyed?

No. The answer depends on the cylinder, product design, condition and available compatible parts. Some requests may be better addressed with a cylinder or hardware change. Identify the actual model and describe the problem before relying on a general claim about a brand.

Smart locks: review keys and electronic access separately

A smart lock may have a mechanical cylinder and separate codes or app permissions. Changing its physical keying does not necessarily reset digital access. Follow the manufacturer’s model-specific instructions when reviewing credentials, and confirm which work is included in the appointment.

A move-in access checklist

List exterior and secondary doors and count their locks.
Check whether every lock operates smoothly.
Identify keys, codes and app permissions handed over at the move.
Decide which access should be retained or changed.
Ask about compatible keyed-alike options and the number of new keys.
Confirm the work and estimate before service.

Schlage’s guidance on when to rekey includes moving and lost-key situations. For a local appointment, check mobile availability in Greenacres or your actual location.

Describe symptoms rather than guessing the fix

Tell the technician whether the key turns, the bolt moves, the door needs pressure or the handle feels loose. These observations help distinguish a keying request from wear, damage or alignment trouble. Avoid repeatedly forcing the key while waiting for an assessment.

Business access needs coordination

A business can have multiple doors, cylinders and credentials, sometimes under a shared or master-key arrangement. Confirm the authorized decision-maker and affected access before arranging changes. Use our commercial locksmith service to discuss that scope.

Check the model instructions and warranty

Rekeying requirements differ by product. Check the manufacturer’s instructions and warranty terms before taking hardware apart. If you are uncertain, ask a qualified provider to assess it. Do not assume a video for another model applies to your lock.

Ask for a recommendation tied to the actual lock

A useful recommendation explains the current condition, compatible options and proposed work. It should address your access-control goal without promising that one service solves every issue. Learn how South Shore approaches service and ask questions about the estimate.

Plan the right work for each door

You may choose different work for different doors: rekey suitable cylinders, repair an alignment issue or replace damaged hardware. Contact South Shore with the lock count, location and symptoms. We provide mobile service; call to confirm availability and an arrival estimate.

Common rekeying questions

Will the old key stop working everywhere?

Only the cylinders included in the rekeying work are changed. Confirm the complete door list.

Can every door use one key?

Only where the relevant locks and keyways are compatible. Ask before assuming a keyed-alike arrangement is possible.

Does a new key reset keypad access?

Mechanical keying and electronic credentials need separate review.
