Changing locks is a complex task. A mistake could result in a ruined lock or even a damaged door. Some homeowners have tried to repair their own locks, but it ended up costing them more money than they originally spent. The cost of hiring a professional is much less expensive than trying to do it yourself. A professional locksmith will know the right steps to take in order to make sure that the job is completed properly.

Before starting the installation process, measure the door so that you can determine what size lock you will need. Some doors have holes pre-drilled for locks, but if not, you will have to drill the holes yourself. If you don’t have a drill, you may have to purchase one, as it may not fit properly. In any case, you’ll need to measure the backset of the lock, as this will prevent you from drilling too deep into the door.
