I’ve lost my house keys—what should I do first?

If you’ve lost your house keys, it’s essential to secure your property immediately. Our lost key replacement service in Newmarket includes both key cutting and lock rekeying, so you won't need to replace the entire lock unless absolutely necessary. Additionally, you can explore our Residential Locksmith Services for a comprehensive overview of how we can help keep your home secure.

Can you make a new key without the original?

Yes, our technicians can create a replacement key for your house or office by working directly with the existing lock. Even if you’ve misplaced the original key, we can cut new keys on the spot using precision tools. If your lock has been damaged during this process, learn more about our lock repair services.

Is rekeying a better option than replacing the entire lock?


Often, yes. Rekeying locks is a quick and effective way to regain control over who has access without removing the entire lock mechanism. We change the internal pins so the lost key no longer works and issue new keys. You can also combine this with upgrades through our lock change service.

What types of keys can you replace?


We handle a wide variety of key types, including:

- Standard house keys
- Office and commercial keys
- Mailbox and cabinet keys
- Smart keys and remote fobs
- Keypad codes and keyless entry systems

If you want to reduce your dependency on physical keys in the future, explore our smart lock installation services for modern, keyless alternatives.

How long does it take to replace a lost key?


Most lost key replacement services take under an hour, depending on the complexity of your lock. In cases where locks are damaged or need upgrading, additional time may be required. Our team works efficiently and professionally to restore access as quickly as possible.

Do you offer services beyond lost key replacement?

Absolutely. In addition to replacing lost keys, we provide a complete range of residential locksmith services, including:

- Emergency locksmith assistance
- Smart lock installation
- House lockout services
- Lock changes and upgrades
- Reinforced door hardware solutions

What if I’m worried someone has access to my lost key?


That’s a valid concern. When a key goes missing, the safest course of action is to rekey your lock or switch to a high-security key system. We recommend acting quickly, especially if your key was labeled or lost nearby. For additional home safety guidance, check out this crime prevention resource from Public Safety Canada.

Whether it’s a misplaced house key, an old tenant's unreturned copy, or a transition to keyless entry, we’re here to help you regain control—securely.
