Can I Rekey a Lock Without the Original Key?

Losing the original key to your lock can be troublesome, especially if you need to change the key to secure your property. The good news is that rekeying a lock without the original key is possible, but the process may require specialized tools and expertise. This guide will walk you through your options and explain how Your Local Locksmith in Las Vegas, NV, can help.

The Rekeying Process

Rekeying involves changing the internal components of a lock so the old key no longer works, and a new one does. It’s usually a simple task if you have the original key, but rekeying without it can be tricky due to locked pins inside the cylinder.

How Rekeying Without the Original Key Works

To rekey a lock without the original key, locksmiths use these techniques:

1. Picking the Lock

The lock cylinder must be removed to rekey the pins inside. Picking the lock allows a locksmith to unlock the mechanism and access the cylinder.

2. Shim Technique

A thin shim slides between the lock cylinder and the housing to push the pins down, unlocking the cylinder without the key.

3. Drilling the Lock

Drilling the lock breaks the pins inside the cylinder, allowing the locksmith to replace or rekey it. This method is more destructive but can be effective for high-security locks.

4. Impressioning

This technique involves creating a new key by making impressions of the lock’s internal pins. It’s often used for older locks or when other methods don’t work.

  • Moving: New homeowners often rekey to prevent past owners from accessing the property.
  • Property Management: Landlords frequently rekey between tenants for security.
  • Security Upgrade: Rekeying allows you to update your locks without replacing the entire mechanism.

  • Quickly rekey your locks using non-destructive methods.
