How to Remove a Broken Key from a Door Lock
2 Answers
Solutions for removing a broken key from a door lock: 1. If the key has just been inserted into the lock and hasn't been turned yet, the main goal is to extract the broken part. If a small portion of the broken key is protruding, gently tap the area around the keyhole with controlled force. The gap between the key and the keyhole allows the key to gradually come out due to inertia. 2. Utilize available tools such as eyebrow tweezers, small pliers, or needle-nose pliers to grip the broken end of the key and gently pull it out. Alternatively, adding pencil shavings, graphite powder, or carbon powder into the lock can increase lubrication, making it easier to remove the key. 3. Use a drill with a small bit to slowly create a thin hole in the center of the broken key. Insert a thin wire or steel thread into the hole and attempt to turn the key. If successful, rotate the key back to its original position and remove it. 4. Pour 502 glue or similar adhesive into the drilled hole. Once the glue has solidified, try removing the key again. If drilling tools or wires are unavailable, directly glue the two broken key parts together. Wait for the glue to set before gently turning and removing the key. Be extremely careful not to let glue drip into the lock cylinder.
When I encounter a key broken in the door lock, I remember the last time my car's ignition lock had an issue and the key head got stuck inside. First, I check the length of the exposed broken key. If it's long enough, I use a fine-pointed pair of pliers to gently grip and pull it out. Sometimes it's stuck tightly, so I spray a bit of WD-40 to lubricate and loosen things up. Avoid pulling too hard to prevent damaging the lock cylinder. If the broken end isn't exposed, I try applying a drop of strong glue to a tool, sticking it to the key, and pulling it out after a few minutes. But be careful not to use too much glue and risk damaging the lock. If all else fails, I use a magnet—if the key is steel, it might be pulled out. Usually, I pay attention to key wear and replace old ones promptly. This issue is especially annoying in rainy weather or emergencies, so now during every car maintenance session, I remind myself to lubricate the lock components—saving both money and hassle. In short, don't panic; most situations can be handled on your own.
