What Does It Mean to Rekey a Lock?

Rekeying a lock is a process that changes the internal mechanisms of the lock, so the old keys no longer work. It’s like giving your lock a fresh start. This involves replacing the pins and sometimes the springs within the lock cylinder. When you insert a key, it pushes these pins to a certain position allowing the cylinder to turn. By changing the pin configuration, you render old keys useless. It’s a cost-effective alternative to replacing the entire lock, and it’s something you can often do yourself.

The Purpose of Rekeying

The main reason people rekey locks is to ensure security. Maybe you’ve recently moved, and you don’t know who has copies of the old keys. Perhaps you’ve had a tenant move out, or you’re concerned about a lost key. Rekeying addresses these security concerns immediately. It ensures that only authorized individuals can access your property. Also, rekeying is a smart idea if you believe there’s been a potential security breach, such as a stolen key. By doing so, you’re essentially resetting access to your property.

• Lost or Stolen Keys: A lost key can cause significant worry. Rekeying eliminates the risk of someone using the missing key to enter your home or business.
• Change of Tenants or Residents: When tenants or roommates move out, it’s wise to rekey to ensure the new occupants are the only ones with a working key.
• Moving into a New Home: You rarely know who has access to the keys to a new home. Rekeying immediately gives you control over access.
• Suspected Security Breach: If you suspect a break-in attempt or any other compromise of your locks, rekeying is a proactive step.
• Upgrading Security: While not directly an upgrade, rekeying offers a chance to review your existing locks and consider more secure options.

Cost-Effectiveness Compared to Replacing

Replacing a lock can be more expensive than rekeying because you’re buying an entirely new lock mechanism, which often requires professional installation. Rekeying is generally much cheaper. It involves changing the internal components of the existing lock, which you can often do with a rekeying kit purchased at a hardware store or with the help of a locksmith. When compared with replacing all of your locks, rekeying becomes even more attractive, particularly if you have several doors to secure.
