Residential Rekeying Services in NH & Southern ME

Secure your home without replacing hardware. Fast, affordable rekeying you can trust.

Why Rekey Instead of Replace?

If you’ve recently moved, lost a key, ended a lease, or just want peace of mind, rekeying your locks is a smart move. It’s often faster and more affordable than full lock replacement, and it ensures that only the keys you hold today will work in your home’s locks.


At A&B Lock and Security, we rekey residential locks across New Hampshire and Southern Maine every day. Our technicians arrive on time, work efficiently, and treat your home with care. Whether it’s a single door or every entry point in the house, we deliver rekeying done right.

“I needed all the locks rekeyed and didn’t want to replace the hardware. A&B made it easy and affordable.” — Stephanie Desjardins

Rekeying vs Replacing Locks

Rekeying

We keep the existing lock hardware but change the internal pins so old keys no longer work. Ideal for new homeowners, landlords, or anyone on a budget.

Replacing

We swap out the entire lock and hardware—useful when upgrading to a different brand, finish, or modern locking technology. We’re happy to help with that too!
