Proof of Residency and Why We Need It

Before we rekey or replace a lock, we verify that you actually own or lease the property. We ask for one of these:

• A current lease or rental agreement with your name and the address.
• A deed or property tax notice (for homeowners).
• A recent utility bill in your name showing the address.
• A government ID with an address matching the lock location.

A Real Case: How We Rekeyed a Condo Without the Key

Last spring, a resident in Islington Village called us in a panic. She’d moved into a condo, lost both keys before she even got furniture upstairs, and the building manager was on vacation. No lease handy. No spare key at the previous tenant’s place.

The old lost key? Useless. Her new key worked, the lock was rekeyed to one key only, and we documented the work in case a future key claim came up (it didn’t).

When DIY Rekey Kits Don’t Work

You can buy rekey kits online for standard locks. They come with a follower tool and new pins, and they do work if three conditions are met:

1. You have the original key to test the lock’s current binding.
2. The lock is a standard residential pin-tumbler (Kwikset, Schlage, or generic Taiwan-made).
3. You’re mechanically patient enough to not strip the follower tool or drop a spring inside your wall.

Since you’ve lost your keys, condition 1 is already out. A professional locksmith can assess the lock and discuss rekeying options when the original key is unavailable. You get the exact price before any work starts.

Related Question We Often Hear

When the Answer Is Different

There are three scenarios where rekeying without a key becomes impossible or inadvisable:

1. The Lock Is Broken or Stuck

Salt spray near Lakeshore or winter ice in Mississauga can affect a lock. If the cylinder will not turn, a locksmith can assess whether replacing it is appropriate rather than attempting a stuck rekey. You get the exact price before any work starts.

2. The Lock Is a Smart Lock

Smart locks do not use mechanical pins to rearrange. Instead, access codes may be reprogrammed in the app or the lock may be reset to factory defaults. If you are locked out of the app or the reset code is lost, a locksmith can assess the smart lock and available door hardware options. You get the exact price before any work starts.

3. The Building Requires a Restricted Keyway

Some commercial buildings and residential complexes use restricted-keyway locks. These locks may require authorization from the building owner before rekeying. A professional locksmith can assess the lock and confirm available options before work begins.

Frequently Asked Questions

1. Do you need proof of ownership to rekey a lock without the original key?

Identification and authorization requirements are confirmed before work begins.

2. How long does a rekey without the original key take?

Rekeying and replacement timing depend on the lock type and condition. If a lock is stuck or damaged, a locksmith can assess whether rekeying or replacement is appropriate.

3. Can a master locksmith rekey any lock without the original key?

Not every lock can be rekeyed. Restricted-keyway systems, digital locks, and severely damaged locks may require replacement instead. A locksmith can assess the lock on-site and explain the available rekeying or replacement options. You get the exact price before any work starts.

4. What’s the difference between rekeying and replacing a lock?

Rekeying keeps the existing lock body and changes the internal pin stack. Replacing removes the entire lock and installs new door hardware. Rekeying may suit a working lock when you need new keys, while replacement may suit a damaged lock or a door hardware upgrade.
