Step 1: Remove the old lock cylinder
To remove the old lock cylinder, you will need to take off the doorknob or lever. Usually, this involves removing a couple of screws that hold the knob or lever in place.

To install the new lock cylinder, simply reverse the steps you used to remove the old one. Insert the new cylinder into the lock, and tighten the screws that hold it in place. Then, replace the doorknob or lever, and tighten the screws that hold it in place.
Step 5: Test the new lock cylinder
After you have installed the new lock cylinder, be sure to test it to make sure it works correctly. Insert the key and turn it to ensure that the lock engages and disengages properly.
