When you get the keys to a new home, you have no way of knowing how many other copies exist. Rekeying the locks is a quick, inexpensive way to make sure the only working keys are the ones you hold.
What does rekeying a lock mean?
Inside most door locks is a set of small spring-loaded pins. A key works when its cuts push those pins to exactly the right heights. Rekeying swaps the pins for a new set, so the lock needs a different key. The lock body, handle and finish stay the same; only the key changes. Done properly, it is as effective as fitting new locks for keeping old keys out, at a lower cost.
You don't know who else has a key
Keys get copied and handed out over the years far more than most people realise. Any of these may still have one:
- Previous owners or tenants, and their family or friends
- Real estate agents or anyone with lockbox access during the sale
- Cleaners, contractors, dog walkers and house sitters
- Former roommates or neighbours who kept a spare
Even when a seller or landlord says every key was returned, a forgotten copy can still be sitting in a drawer somewhere.
A small job with a big security payoff
Rekeying usually costs less than replacing locks, and a locksmith can often do several doors in one visit. While the locks are apart it is also a good moment to key all your exterior doors alike, so one key opens the front door, back door and garage entry.
Renting? Ask before you change anything
If you rent, ask the landlord or property manager to rekey before you move in. If they won't, ask for written permission to have it done yourself and check what your lease says about providing them with a copy of the new key. Rules vary by lease and location, so get agreement in writing first.
Rekey after renovations too
If builders, decorators or other trades had keys while work was done, rekey once the job is finished, particularly if you can't confirm that every copy came back.
Rekeying or replacing: which is right?
Rekey when your locks are in good condition and you simply want old keys to stop working. Replace when locks are worn, rusty or damaged, when you want a higher-security or smart lock, or when you want a different style of hardware. A locksmith can look at each door and recommend the right option.
