Moving into a new home, condo, or rental property is exciting, but the keys you receive at closing do not tell you who may still have a copy. Previous owners, tenants, contractors, cleaners, property managers, or neighbors may have been given keys over the years. Rekeying is a practical way to reset access without necessarily replacing every lock on the property.
What Does Rekeying a Lock Mean?
Rekeying changes the internal pin configuration of a compatible lock so that the old key no longer operates it. The existing lock body and most of the visible hardware stay in place, but a new key is created for the updated configuration. This is different from replacing a lock, which involves removing the current hardware and installing a new lockset.
If the hardware is in good condition, rekeying can be an efficient solution. If a lock is damaged, heavily corroded, poorly aligned, or no longer provides the level of security you want, replacement may be the better choice. Our guide to rekeying versus replacing locks explains the difference in more detail.
Why New Homeowners Should Consider Rekeying
- Unknown key history: You cannot confirm how many copies were made before you moved in.
- One-key convenience: Compatible locks may be keyed alike so one key operates several exterior doors.
- Controlled access: Old keys stop working after the locks are rekeyed.
- Security review: A locksmith can examine the condition, operation, and alignment of the existing hardware while performing the service.
Which Doors and Locks Should Be Checked?
Start with every exterior entry point, not only the front door. A complete review may include the back door, garage entry door, side door, patio or sliding-door lock, gates, storage rooms, mailbox locks, and any door connecting the garage to the living area. Condo owners should also consider building rules and association requirements before changing common-area or restricted key systems.
Do not assume two locks that look similar use the same keyway or can automatically be keyed together. Compatibility depends on the manufacturer, cylinder, condition, and design of the hardware.
When Is Lock Replacement the Better Option?
Rekeying does not repair every problem. Replacement may be more appropriate when the lock is loose, worn, damaged, unreliable, difficult to operate, or affected by corrosion. Replacement also makes sense when you want to add a deadbolt, upgrade to a keypad or smart lock, improve key control, or change the style and function of the door hardware.
South Florida heat, humidity, heavy rain, and salt air can accelerate wear on exposed locks. If a key sticks or the bolt does not move smoothly, the problem may involve the door alignment or hardware—not only the key. Learn more about how South Florida weather affects door locks.
Should You Rekey Before or After Moving In?
Ideally, schedule the work as soon as you receive legal possession of the property. If renovations, cleaning, painting, or contractor work will continue after closing, you may prefer to coordinate access first and complete the final rekey once temporary access is no longer needed.
Before the appointment, count the exterior locks, note which doors you want to operate with the same key, and identify any locks that feel loose or difficult to turn. Having this information ready helps the locksmith evaluate the appropriate options.
What About Smart Locks and Keypads?
Changing an access code is helpful, but it may not address every form of access. A smart lock may still have a physical key cylinder, connected user accounts, stored codes, or app permissions from the prior resident. Reset the device according to the manufacturer’s instructions, remove old users, update the administrator account, change the codes, and confirm that the physical key is controlled.

Frequently Asked Questions
Do I need to replace every lock after buying a house?
Not necessarily. Locks that are compatible and in good working condition may be rekeyed. Damaged, worn, incompatible, or outdated hardware may need replacement.
Can multiple doors use the same key?
Often they can, but the locks must have compatible keyways and cylinders. A locksmith should inspect the hardware before confirming a keyed-alike setup.
Will the previous keys stop working?
Yes. After a compatible lock is properly rekeyed, the previous key will no longer operate that cylinder.
Should renters rekey their locks?
Renters should obtain the property owner’s or manager’s approval before changing or rekeying locks. Lease terms and building policies may control what changes are permitted.
