The solution to the lock key breaking in the lock cylinder in the lock manufacturing process is as follows:
1. Find a hammer and tap lightly around the keyhole. The broken key will return to its original position and be exposed. You can use a sharp object to pick it out.
2. Make a single hook with thin iron wire, insert it into the lock hole, hook the top of the key and come out along the lock hole.
3. Hold the exposed key with tweezers and pull it out with force.
4. The cross lock should use the drill bit of the electric drill to drill the gap of the lock hole a little bigger.
5. The wire hook goes in, and sticks the broken key with 502 glue and pulls it out.
6. Use the broken thin shackle padlock key to apply 502 glue and quickly stick it with the short stubble inside and pull it out gently.
