Why you should rekey your locks when you move

When you get the keys to a new home, you have no way of knowing who else has a copy. Rekeying is a quick, affordable way to make sure the only working keys are the ones in your hand.

What rekeying means

Inside a pin-tumbler lock is a stack of small pins cut to match one key. Rekeying replaces those pins with a new set, so the old key no longer lines them up and a new key does. The lock body and finish stay the same. It's just as effective as fitting a new lock at stopping old keys, and it generally costs less.

1. You don't know who has a key

Previous owners, past tenants, real estate agents, neighbours who watered plants, cleaners, contractors and dog walkers may all have had keys at some point. Even if the seller or landlord says every key was returned, copies are easy to make.

2. It's a small cost for a real upgrade

A locksmith can usually rekey several doors in a single visit. While we're there, we can key the front, back and garage doors to one key, so you carry fewer keys.

3. Peace of mind

Knowing that only your household can open your door removes a nagging worry, especially for families with children or anyone living alone.

4. Renters: ask first

If you rent, ask the landlord or manager whether the locks were rekeyed after the last tenant. If they weren't, ask them to arrange it, or ask permission to have it done yourself. Most leases require the landlord to keep a working key, so give them a copy.

5. Rekey after renovations too

If contractors, painters or electricians had keys during a remodel, rekeying once the work is finished closes that loop, even if you've lived there for years.

Rekey or replace?

Rekey if your locks are in good condition and you simply want old keys to stop working. Replace if a lock is worn or damaged, if you want a higher grade or a smart lock, or if you want a new look. We'll quote both options so you can choose.

Book it before you unpack

The ideal time to rekey is moving day or the day after. Call 626-537-3965 or see our residential services.
