Rekey or replace your locks?
Rekeying changes the pins inside your existing lock so it works with a new key. Old keys stop working, and you keep the hardware you already have. It’s the cheapest way to secure your home. Replace the lock when it’s damaged, worn out, low quality, or when you want a different look or a smart lock.
| Rekey | Replace | |
|---|---|---|
| Price per lock | $30 – $55 | $65 – $110 install, or $120 – $220 with a new deadbolt |
| Old keys stop working | Yes | Yes |
| Keeps your current hardware | Yes | No |
| Best when | Locks work fine, you just need new keys | Lock is broken, worn, or you want an upgrade |
When to rekey your locks
You just moved in
You don’t know who still has a key — previous owners, contractors, neighbors.
Lost or stolen keys
Especially if your address was with the keys.
Tenant turnover
Landlords and property managers: rekey between every tenant.
Too many keys
Put the front door, back door and garage on one key.
One key for every door
Our whole-home package puts up to 4 locks on a single key, so the front door, back door, side door and garage all open with the same key. If your locks are different brands, we’ll tell you on the phone whether they can be keyed alike.
Master key systems for landlords and multi-unit homes
Own a duplex, a rental, or a home with an ADU? A master key system gives each unit its own key while one master key opens every lock. Tenants can’t get into each other’s units, and you don’t carry a ring of 20 keys. Master key systems are quoted per project, based on the number of doors. For offices and commercial buildings, see Commercial Locksmith.
How it works
- Call or request a quote and tell us how many locks and what kind.
- Get your price within the ranges above before we dispatch.
- We confirm the total at your door before starting.
- Rekey or install each lock and cut your new keys.
- Test every lock with the new keys — and show you the old keys no longer work.
