Locksmith On Demand provides professional lock rekeying services in Newmarket, helping homeowners, landlords, and businesses maintain security without replacing the entire lock. Our licensed locksmiths reset the internal pins of your existing locks so they work with a brand-new key, making all old keys useless. Rekeying is a fast, affordable, and reliable solution when moving into a new property, losing keys, or changing tenants, giving you full control of access while keeping your existing hardware in place.
We recommend rekeying when:
You never know who still has a copy of the old key.
Don’t risk it—render the old key useless and regain control.
It’s a smart move for your peace of mind.
Ensure past staff can’t access your office or facility.
Over time, you lose track of who has access.
We can rekey multiple locks to match the same key—super convenient!
We don’t just rekey—we help upgrade and improve your entire lock system:

Get extra copies made for your household, tenants, or team.

Ideal for landlords and offices—multiple locks, one master key.

We can rekey traditional locks or install new keyless systems if preferred.
