Gera 6500mc
today I bought a Gera 6500mc. The special thing about this lock is , that is has one springless chamber with a pin, which needs to be lifted up by a magnet in the key.
I think that this "magnet pin" can easly be bypassed by turning the lock upsite down. If it's in a door you may need something like magnetic pick or a small magnet which fits in the keyway.
