How to Disassemble a Deadbolt Lock

Disassembling a deadbolt lock is a necessary step when replacing an old deadbolt lock with a new one. It is a good idea to pay attention to what you are doing to remove the old deadbolt if you are replacing it with a new deadbolt of the same brand. Even if you are switching brands, most deadbolts assemble in similar ways. The differences may be minor, so if you are replacing an old deadbolt, disassembling the existing deadbolt will be the reverse of installing the new one.
