It’s possible that if you have a problem with your lock, your door will not open. The key moves all the way whether you spin it from the outside or from the inside. The lock, on the other hand, does not budge. You will be unable to open your door if the deadlock does not travel far enough. Knowing how to repair a deadbolt that won’t unlock is important since it allows you to address the problem.

One solution

Remove the screws that keep the lock in place and then remove the deadbolt from the door. For examination, the thumb turn mechanisms must also be removed. Continuous use may cause these components to jam, and they will need lubrication after a complete cleaning. If a prior attempt to force the lock resulted in one of the deadlock’s components being bent, you have a few alternatives for repairing it. A pair of pliers will be needed to straighten the bent component. The bent component also indicates that you are employing a low-quality deadbolt, which should be changed. If you’re worried about getting the key to your new deadbolt, a locksmith can assist you. Any debris caught in the mechanism will need to be removed as well. It will guarantee that your deadbolt functions as intended.

Option two:

It gets more difficult to lock and unlock your deadbolt after several years of usage. The tension that the bolt experiences as a consequence of being misaligned with the frame typically causes the bolt to break. In this situation, unscrewing the lock from behind is the most effective approach. You can easily open the door after the lock has been removed. You’ll need to go over your deadbolt for any indications of wear or fracture. In certain instances, you may need to replace your bolt and file the strike to avoid encountering any further difficulties when attempting to open it. When the deadbolt is not properly aligned, it can enter the deadbolt hole at an angle rather than horizontally. If your door still won’t open, try lifting it a little to see if the deadbolt can be freed enough to retract. If none of these methods work for your door, the angle is the issue, which you may correct by adjusting the receptacle plates and tightening them up a little. You may also try slamming the door shut to see if that works. Whether this doesn’t work, you’ll need to investigate the components more and clean them up to determine if they’re still useful.

Solution number three

You may need to replace the cylinder on a multi-lock or an Assa Abloy deadbolt. When you take the deadbolt apart to replace the different components, make sure you use new screws when putting it back together. Take apart the deadbolt and replace the screws to correct misalignment. When the screws are properly installed, the deadbolt will line with the deadbolt hole, allowing it to lock properly. Some of the internal components may have become old and worn out after years of usage. As a result, they will not function as anticipated and will need to be replaced.

Solution number four

Many deadbolts that refuse to open have been found to benefit with dry Teflon. It will take around five minutes for the Teflon to take effect once you have sprayed the Teflon into the lock. The major reason your deadbolt isn’t functioning as it should is due to a lack of maintenance. Teflon is preferable to graphite since it will spray on wet and absorb into the lock mechanisms over time. In addition, after the solvent has completed its task, it will evaporate, which is quite handy. To ensure that the Teflon penetrates in, try rotating the locking mechanism around after spraying it with it. Within a few minutes, the Teflon should have worked its magic on all the stuck components of the locking mechanism, and you should be able to open your deadbolt without any problems.

Solution #5:

When a deadbolt is stuck in the locked position for an extended period of time, it is generally an indication that it has been neglected for a long time and will not move. Some of the components that had been disengaged may slip back into position if you tap gently on the deadlock with a tiny hammer. Your deadbolt may be unlocked once again with a little gentle tapping. If you opt to unscrew your lock, double-check that the rod is properly aligned with the inner slot. It’s preferable if the rod is pushed back into position and the deadbolt is checked to see whether it’s unlocking. While the door is still open, you may test to see if you have an alignment problem or if the door is not properly aligned with the frame. Other components may be out of position as a result of the alignment issues, which is why this method to repairing the stuck lock on your door is used.


When a deadbolt fails to unlock, it is typically stuck in the locked position. There are a variety of causes for this, including worn-out components, misalignment, and pieces that aren’t in the right position. When confronted with such a problem, any of the five methods listed above will assist you in resolving the problem. Make sure you attempt as many different methods as possible in order to solve the issue. If none of the above techniques work, you may hire a locksmith to disassemble your locking mechanism and examine your deadbolt for defects and structural damage.
