Why you should rekey your locks when you move

When you get the keys to a new home, you're rarely getting all of them. Rekeying is the simplest way to make sure only your household can get in.

What rekeying means

Inside a pin-tumbler lock are small pins set to match one key. Rekeying swaps those pins for a new set, so a new key works and the old ones don't. The lock body, handle and finish stay the same. Done properly, it's as effective as a new lock against old keys, and it costs less.

1. You don't know who has a key

Previous owners or tenants, their family, real estate agents, contractors, cleaners, pet-sitters and old roommates may all have had copies. Even if the seller says they handed over every key, there's no way to know about copies cut along the way.

2. It's quick and affordable

A competent technician can rekey several doors in a single visit. If you'd like one key for every door, it can usually be done at the same time when the locks share a keyway.

3. Peace of mind

Your home should feel like yours. Knowing the only working keys are the ones you hold is worth the small cost.

4. Renters: ask first

Most leases don't allow tenants to rekey without the landlord's permission, because the landlord needs emergency access. It's reasonable to ask your landlord to rekey before you move in. If they agree to let you arrange it, give them a copy of the new key.

5. After renovations

Contractors often hold keys for weeks. Once the work is done, rekeying is good practice.

Cost

Rekeys start at $19 plus the $29 service call on the price list, with a 30-day warranty from the contractor. The Move-In Special gives 15% off.
