2. Remove the Existing Lock:

Next, start by removing the old doorknob. Unscrew the old doorknob pieces on both sides of the door, then gently pull them apart. Following this, remove the screws from the edge of the door that are holding the latch in place, and then take out the old latch.

3. Preparation for New Lock Installation:
Furthermore, if your new lock is a different size than the old one, you may need to adjust the hole in the door or the latch plate on the door’s edge. Use a chisel for any necessary adjustments.
