Identifying a broken door lock 

A broken door lock is not just a nuisance; it can also be a potential danger. A broken door lock will prevent you from locking and unlocking your door quickly, which is crucial in emergencies. In addition, a broken lock can result in jams and other problems. This article will explore how to identify a broken door lock and solve the problem. 

While it may be tempting to call 911 to have an emergency locksmith come to your home, identifying a broken door lock on your own may be a more cost-effective option. First, identify the problem by noting the cause of the problem. If the problem is minor, it might be possible to repair the lock yourself. 

Repositioning a strike plate 

If your door lock has broken, repositioning a strike plate can be a quick and easy fix. It is important to make sure that the plate is in the correct position and that the screws are tightly secured. If the strike plate is bent or damaged, it will make it more difficult for the door lock to catch and function properly. This repair will require a few tools. 

In order to do this, you must first remove the strike plate from the jamb. If the strike plate is loose, it will scrape against the latch when the door is closed. You must also make sure that the screw head is flush with the door jamb. 

Changing a cylinder 

If your door lock is malfunctioning, changing a cylinder is a good way to fix it. Before you begin, you must know how to disassemble the cylinder. This is typically done by unscrewing two screws that secure the cylinder to the lock case. To loosen the cylinder, you can use penetrating oil on the screw threads. Once you’ve removed the screw threads, you can start the replacement process. 

Changing a cylinder is a simple process. First, you need to measure the cylinder. You will need to measure the distance from the center of the cylinder to the left or right end of the carrier. Once you’ve measured the distance, you can then buy the correct cylinder. 

Removing a broken key 

If the key has been broken off in the lock, you can try to extract it by using a pair of needle nose pliers. Another option is to use super glue and a coping saw blade. However, be sure not to push the key too far and risk damaging the lock’s core. 

In most cases, the broken key is not able to engage with the lock. A small metal rod or paper clip can be used to push the key out. Another option is to bring the lock to a locksmith.
