Why Home Lock Rekeying Belongs at the Top of Your Moving Checklist
When a home changes hands in Ontario, there is no legal requirement for the seller to guarantee that all key copies have been returned. In practice, they rarely are. A typical Vaughan resale home may have had keys cut for family members, dog walkers, house cleaners, and the original builder — none of whom are obligated to hand them back. Rekeying neutralizes every one of those copies instantly. The locksmith disassembles the lock cylinder, replaces the internal pins with a new configuration, and reassembles it — now only the new key will operate the lock. Every previous copy becomes useless metal the moment we finish.
This is fundamentally different from a full home lock change, where the entire lock hardware is swapped out. Rekeying keeps your existing hardware in place and only alters the internal mechanism. That means less time, less disruption to your door frame, and no unnecessary spending on hardware you don't need to replace. If your locks are in good mechanical shape — common with newer builds in areas like Vellore Village or Patterson — rekeying is almost always the smarter starting point.
