Securing the front door against burglars
Take a not too thin wire, 25 - 30 cm long, and bend it to a safety fork - similar to a hairpin.
Now hang the finished fork on the pawl and loop the two ends around the ring of the key that you put in the lock.
The key can not be turned around or pushed out from the outside.
The security against burglars is ideal and costs nothing.
