Assemble These Tools Before Rekeying Your Lock
Ready to become a DIY lock changer? Start by assembling the right tools and components:
- The rekeying kit (for your brand lock)
- Needle-nose pliers
- A 4-in-1 screwdriver
Once you’ve collected these tools in one spot, follow our step-by-step guide to make the process go smoothly.
A Step-by-Step Guide to How to Rekey a Lock
To rekey a lock, you’ll need to complete five steps:
- Take off the doorknob.
- Separate the knob and lock cylinder housing.
- Remove the retainer ring.
- Take off the cylinder plug.
- Reconfigure the pins and springs to your new key.
Let’s explore each of these steps in greater detail. First, remove the doorknob. You’ll do this by inserting the wire tool included with your kit into the knob hole and placing pressure on the knob clip.
Second, grab the current key copy that we told you to set aside. Insert it in the lock and turn it to unlock your house. Then, remove the knob and lock cylinder housing with the key.
Third, take off the retainer ring using the retainer ring tool. Put the tool around the retainer ring and then apply pressure to “pop” the thin retainer ring off. Once you’ve freed the ring, set it in a safe place as you’ll need it again for reassembly.
Fourth, it’s time to remove the cylinder plug from the cylinder. To do this, insert the current copy of your key and turn it to the left or right. This action will allow you to remove the plug by pushing the plug follower.
The plug follower is another tool found in your kit. While you’re removing the cylinder plug, you must keep consistent pressure between the follower and plug until it’s completely removed. Otherwise, the springs and pins will pop out.
Fifth, dump out the old pins. Then, insert the new key. Grab a pair of tweezers or small needle-nose pliers and arrange the colored pins to match those of the color code. This color code comes with the instruction sheet.
Once these pins get inserted in the proper order, reverse the steps in the process to install the rekeyed lock.
