Detailed Steps to Rekey a Lock

Preparing for Rekeying

The very first step to rekey a lock is to get a rekeying kit specific to the brand of your lock. These have everything, even different-sized pins, and a key gauge for ease.

Removal of the Lock Components

The process of rekeying locks by a locksmith begins with removing the doorknob, which generally requires the knob to be unscrewed through some holes on the sides of the knob using a tool. After this, the cylinder is to be removed from the knob assembly for disassembling.

The Rekeying Process

On the other hand, use that hand, which previously had the follower tube, to pull the key plug and the follower tube out of the cylinder with the c-clip. This, in turn, allows you to dump out the old pins and install new ones according to the specifications of your new key. It is a precise process to ensure the new key properly operates the lock.

Reassembling and Testing

Installation of all the new pins is followed by the insertion of the plug in the cylinder, and after that, the knob is attached to the door again. Now, you have to put your new key in to test a couple of times that your rekey has been successful.

Rekeying a Deadbolt

The deadbolt works on much the same principle as the doorknob. If it’s the same brand as the deadbolt, then deadbolt rekeying is quite simple and allows you to have a unified key system throughout your house.

Deciding Between Rekeying and Changing Door Locks

In some cases, changing the door lock rather than rekeying would be better. For example, wearing locks or updating the house’s appearance calls for the replacement of locks. Other instances include a condition where you have locks with different brands and want them to have just one key; you should change all your door locks to just one brand before rekeying.
