Deadbolt locks are most common in the United States. These locks are strong and not easy to break. It is not easier for criminals to break in if the deadbolt lock is fully functional. The deadbolt locks do not have a spring activated in them, so they work better. The most common issue faced in working on these locks is blockage in the hole. Some installers do not dig the hole in the door jamb deep enough for the bolt to extend properly and lock the door. Before knowing the details about fixing an improperly installed deadbolt, you must learn the structure and workings of a deadbolt lock.

The main body of the deadbolt lock is known as the cylinder. It is where the key is inserted, and the cylinder rotates to open the lock.
Bolt
A bolt is a piece of metal that extends from the door into the frame in order to lock the door.
Thumb latch
It’s the part of the lock that extends from the surface and is used to operate the deadbolt from inside.
Strike plate
It is a metallic plate installed on the door jamb over the hole for the deadbolt lock. It enhances security by covering the hole for the deadbolt.
How does it work?
Deadbolt locks do not have a spring system. They are operated manually with the help of a key or thumb latch for locking from outside and inside, respectively. When the cylinder of the lock rotates, it extends the bolt to enter the hole in the door jamb, and the door gets locked.

Suitable Hole Size for a Deadbolt?
Usually, for a deadbolt lock, a hole minimum of 1 inch deep is required. In which the bolt can be extended fully making the door locked for security purposes. If the hole is not deep enough it will not let the deadbolt lock work properly.
How to Fix an Improperly Installed Deadbolt?
A deadbolt lock only keeps the bad guys out if it’s installed properly. A deadbolt lock is only secure when the bolt is fully extended into the door frame. If it isn’t fully extended, it’s possible to unlock the door without a key, as the deadbolt hole is not deep enough. We show you one common problem with deadbolt lock installations that’s easy to identify and easy to fix.
Tools & Materials Needed
- Electric drill
- Spade bit for drill
Steps To Inspect and Repair an Improperly Installed Deadbolt Lock
- Test the deadbolt by turning the twist knob to latch and unlatch the lock with the door open and then again with the door closed. If the twist knob lever stops in the same position for both tests, the strike plate and hole are most likely installed properly.
- If the twist knob stops short when the door is closed, the hole in the door frame has not been drilled deep enough, which could make it easier for a criminal to defeat the lock.
- Remove the strike plate from the door frame. Do not try to deepen the hole without removing the plate. If you don’t remove the strike plate, the opening will not be wide enough for the spade bit, and it could snag, causing the drill to buck. This could easily injure you or damage the door frame. Safety is the most important thing to keep in mind when using tools.
- Using the appropriate-sized spade bit and an electric drill, cut the hole in the door frame about 1/4 inch deeper.
- Test the latch mechanism again. If the twist knob stops in the same position with the door opened and closed, the hole is deep enough. If not, use the drill to make the hole another 1/4 inch deeper.
- Test the deadbolt latch again, if necessary.
- If the lock tests properly, re-install the strike plate and test the lock one more time to make sure the bolt is not snagging on the door frame.
Precautions for This Process
While fixing the deadbolt lock, it is important to operate the drill carefully. Wear safety glasses or a face shield. Make sure that the strike plate is removed before drilling. If it gets mishandled, it may damage the door jamb, leading to a bigger loss. So, It is better to call an expert to perform such tasks.
