The invention relates to a lock comprising a locking body (2) that can be securely fixed to a vehicle, houses a locking mechanism (5) and comprises at least one piston opening (3) for receiving a locking piston (4) that is located on a free end of a locking element. The locking body (2) contains a motor (6) and a motor-displaceable bolt influencing member (7) for displacing at least one bolt (8) between a locking position that secures the locking piston (4) in the locking body (2) and a release position that releases the locking piston (4). The bolt influencing member (7) acts on the bolt (8) outside the transmission chain of forces from the locking body (2) via the bolt (8) and the locking piston (4).
