Problems with a car door lock are exacerbated if the mechanical key has broken and a fragment remains in the keyhole. In such situations, attempting to do anything yourself is difficult and can only worsen the situation.
It’s best to contact specialists, such as Turoffnung Hansaviertel.
Opening Methods
There are several options for opening doors with a broken key:
- Call a professional locksmith. They have experience, the appropriate tools, and knowledge of the lock’s features, and can perform gentle opening operations. This is the most reliable method.
- If part of the key is sticking out above the keyhole, you can use pliers, carefully grasp the tip, and gently pull it out.
- Before pulling, it’s recommended to add a small amount of WD-40 to increase lubrication and improve the movement of the fragment. Do not turn the key during this process, as this movement can jam the fragment or the lock itself.
- A magnet can be used to remove the fragment, provided it isn’t stuck too far inside the keyhole and the key is made of steel or other materials with good magnetic properties. A jigsaw blade is serrated and thin, so it can be inserted into the keyhole, catch the broken piece, and pull firmly. This method can damage the lock, so care is required.
- Drilling the keyhole involves inserting a thin drill bit directly into the keyhole, widening it. After this, the lock will have to be replaced.
- Various lock picks are used, but you need to know how to use them.
As can be seen from the methods listed, in most cases, it is possible to remove the broken piece without vandalism and leave the old lock working.
Tips
A broken key in a car door lock is not a cause for panic. In some cases, the problem can be solved independently if you have the right tools and understand the design of the locking mechanism.
However, if the key breaks while turning, complications may arise: the keyhole will need to be reset, which is difficult if the broken piece is deeply lodged.
Therefore, the situation should first be assessed, the nature of the breakage should be determined, and only then should a repair method be chosen. If the broken piece isn’t sticking out or the lock is turned, you’ll need to call a professional. Any attempts at self-inflicted damage will only worsen the situation, leaving you with no other options but vandalism.
The best, most cost-effective option is to call a professional car lock repair technician.
