Lock Rekey & Replacement
New place or lost keys? Make sure only you hold access.
Rekeying changes the pins inside your existing lock so old keys no longer work — ideal after moving in or losing a key, and cheaper than replacing the hardware. My Locksmiths rekeys most home locks on site from $25 per lock.

Real reviews from homeowners and businesses we've helped across the Greater Toronto Area.
Locked out at 1am with a newborn inside. They answered immediately and had someone at my door in 22 minutes. Calm, professional and no damage to the door.
Priya S.TorontoRekeyed every lock the day we got our keys. Clear pricing over the phone that matched the invoice exactly. Exactly what you want from a locksmith.
Marcus D.MississaugaWe needed a master-key system for our office of 30. They mapped out access levels, installed everything after hours, and trained our office manager. Flawless.
Jennifer L.OakvilleBroke my key in the deadbolt in the middle of winter. Extracted it, replaced the cylinder and I was inside in under half an hour. Lifesavers.
Amir K.VaughanInstalled two smart locks and walked me through the app setup. Friendly, tidy and genuinely knew the products. Booking again for my rental.
Chloe M.EtobicokeStorefront lock jammed an hour before opening. They prioritized us, fixed it fast and we never lost a minute of business. Highly recommend.

Lock Rekey & Replacement FAQ
Common questions
Should I rekey or replace my locks?
If your locks are in good working order and you simply want new keys, rekeying is faster and cheaper. Replace the hardware when it's worn or damaged, or when you want to upgrade to higher-security or smart locks.
Can you make all my locks use one key?
Yes. As long as the locks are the same brand and keyway, we can key them alike so a single key opens every door.
How much does rekeying cost?
Rekeying typically starts around $25 per lock plus the service call. We confirm the exact total upfront before starting.
