The first step is to make sure that you’ve got all the tools that you need. It’s important to have a variety of tools on hand, including a screwdriver, as well as a drill with the correct bit for your particular type of lock. 

If your door lock doesn’t work properly, it may need to be re-keyed or replaced entirely. You’ll need a new key to replace the existing one, and you’ll need to test it with the door closed before re-keying it. 

This is the most common problem with door locks, and it’s easy to repair. Here’s how: 

1. Remove the mortise lock and its spindle

If you have a mortise lock, the easiest way to remove it is to use a hammer and a player. You can also grab a large flat-head screwdriver and pry it out with a few good pulls. 

  1. If you’re not comfortable taking the lock off your door, call a professional locksmith to help you out. They’ll be able to help you out of a jamb or replace the lock altogether, depending on the type of lock that’s in place.

3. Fix a faulty door lock and its hardware

There are some things that can cause a faulty door lock, and these include a worn-out hinge, a missing or incorrectly positioned deadbolt or handle, a broken bolt, or the door frame and/or jamb that’s not securely attached to the framing. 

Luckily, these issues are relatively easy to resolve, and they won’t cost you a fortune in labor. In most cases, you can just buy a new lock and have it installed by a locksmith. 

4. Re-key a cylinder lock

A faulty cylinder lock is very common, and it’s very simple to repair. You’ll need a new key, and you’ll need to make sure that the cylinder cam tongue is aligned correctly with the lock body. This is an important aspect of ensuring that the lock will work as expected, so it’s best to have a professional help you out with this job. 

5. Replace a knob lock

Knob door locks are often used in conjunction with a deadbolt on exterior doors, but they can also be used for internal and back-of-house areas. They aren’t the most aesthetically pleasing option, but they are a great choice for high-traffic areas. 

6. Replace the interior knob with a new one

You’ll need to remove the decorative rose plate on your exterior doorknob to gain access to the interior knob. This will be a fairly easy process, as long as you’re careful to not damage the rose plate. 

Once you’ve removed the decorative rose plate, you’ll need to unscrew the two screws that hold the interior knob to the faceplate of the lock. If you’re not sure how to do this, call a professional locksmith like Paragon Security, and they’ll be able to help you out.
