Understanding and Mastering Lock Rekeying for Enhanced Security

Lock rekeying is an essential process in maintaining enhanced security for your home, business, or any premises requiring secure entry. Rekeying a lock involves changing the internal components, specifically the pins, so that a new key can be created to open the lock. This process can also allow you to key multiple locks to one new key, enhancing convenience and security. Understanding the various techniques and steps can help you make informed decisions about your home's security.

Methods of Rekeying a Lock

There are several methods to rekey a lock, each with its own advantages and applications. Whether you want to replace individual locks, key a set of similar locks, or create a multi-level masterkey system, there are several options available:

Replacing Bottom Pins: By changing the bottom pins to differing lengths from the existing ones, you render the old key non-functional. A new key needs to be cut that matches the new pin configuration. Keying to an Existing Key: Install pins of the correct length for the existing key, making the lock compatible with that key. Masterkeying: Keying sets of locks to one key, allowing them to all be opened with a single master key. This can include multi-level masterkey systems and maison key systems where multiple different keys can open the same lock. High Security Levels: Replacing standard pins with specialized ones can enhance the lock's security, making it more resistant to picking.

DIY Lock Rekeying Ventured

For those comfortable with the process, rekeying locks can be a DIY project. However, certain conditions might necessitate the assistance of a professional locksmith. Some key points to consider include:

Yale Locks: Yale-type locks are generally straightforward to rekey, especially if you replace the cylinder. Most hardware stores offer a new cylinder with two keys, and additional keys can be cut for around ￡1.75 each. Mortise Locks: If you have mortise locks, a professional locksmith or skilled handyman might be required to replace the locks as it's often a more complex task. Loss of Keys: If you have lost your keys or they have been stolen, a locksmith will be able to rekey the lock. This process can also be used to change access codes during a home move or for security updates.

Steps to Rekey a Lock

Proper rekeying involves a series of steps. The process can be broken down as follows:

First, create a new key or use an existing other key to key the lock to be the same. Remove the lock from the door. Disassemble the old lock cylinder using the existing old key, ensuring no top pins and springs are lost. Remove the existing bottom pins from the core. Insert the new key into the core and add new bottom pins so that their tops are flush with the surface of the core. Minor filing may be necessary. Reassemble the cylinder and re-install the lock back into the door.

Conclusion

Rekeying your locks can significantly enhance the security of your property. Whether you choose to do it yourself or consult with a professional locksmith, it's crucial to understand the process and available methods. Whether it's replacing bottom pins, keying to an existing key, or creating a complex masterkeying system, the choice is yours. Remember, maintaining your locks effectively is an investment in your safety and security.
