Rekeying is the most underrated tool in home security: instead of replacing your locks entirely, we change the internal pin configuration so your old keys stop working and new ones take over. It's the standard move after moving into a new home, after a roommate or tenant moves out, after losing a key you can't account for, or simply after a few years when you're no longer certain who might have a copy floating around.

Because rekeying works with your existing hardware, it's typically faster and less expensive than replacing locks outright — and we can rekey every exterior lock in your home to a single new key, so you're not juggling a different key for the front door, back door, and garage entry. If your current hardware is worn out or you want to upgrade security grade at the same time, we'll flag that honestly rather than rekey a lock that's on its way out.

How It Works

Hardware check

We inspect each lock to confirm it's rekeyable and in good working condition before quoting.

Pin replacement

The cylinder is opened and the internal pins are swapped to match a new key combination — no new hardware needed.

Keyed-alike setup

If you have multiple doors, we rekey them all to a single key on request, at no extra runaround for you.

New keys cut and tested

You get fresh keys cut on the spot, tested in every lock before we leave.

What Affects Pricing

  • Number of locks being rekeyed
  • Whether all locks are being keyed alike to one key
  • Lock brand and pin-count complexity
  • Number of replacement keys needed

Rekeying multiple doors to one key is almost always cheaper than buying and installing new lock sets.

Frequently Asked Questions

No — the lock hardware itself stays exactly the same. Only the internal pins change, so old keys stop working and new ones take over.
In many cases yes, as long as the cylinders accept a compatible keyway. We'll confirm this during the on-site inspection.
Most homes with 2–4 exterior locks are done in under an hour.
