Lock Rekeying in Hamilton, ON
Rekeying is the most cost-effective security reset you can make — and it's one of the most common calls we get in Hamilton. Moving into a new home? Tenant just moved out? Lost a set of keys? Just had a break-in attempt? All strong reasons to rekey. AS Locksmith handles rekeying calls across the full Hamilton area, same day.

Same-Day Rekeying Across Hamilton
Hamilton's large and active rental market — driven significantly by McMaster University in Westdale, Mohawk College on the Mountain, and a strong downtown rental corridor — means tenant turnover is a constant reality for Hamilton landlords and property managers. We work with property managers throughout the city to turn properties quickly and affordably. A full home rekey (3-4 locks) is typically completed in under an hour with new keys cut on-site.
Rekeying changes the internal pin configuration of your existing lock so all old keys — the previous tenant's copies, any keys they had cut, anything the previous owner gave out — immediately stop working. The hardware stays exactly the same. You get brand new keys and complete control over access. We can also set up a keyed-alike system so every door on your Hamilton property opens with a single key — simple, secure, and no more bulky keychains.

Rekeying vs Replacing — Which Do You Need?
- Rekey if: Your lock hardware is in good working condition and you just want to deactivate old keys — most affordable, same security as new locks.
- Replace if: Your lock is visibly damaged, worn, or a lower security grade than you want.
- Not sure? We'll inspect your current hardware on arrival and give you an honest recommendation.
