Put a tube of hot glue on the lock, this prevents you from inconvenience

By inserting this heated glue tube into the lock, you will notice how the key piece can adhere to it. Once everything has “solidified”, so to speak, you can try to extract the tube. If you are lucky, you can also extract the broken key inside.

A very practical and simple tip to use only when needed. You could avoid calling an emergency technician. Our invitation, however, will be to understand in the future the problem that led to the locking and breaking of the key, so that we no longer have similar problems.
