Abstract
There is provided a lock with a locking function of a bolt to be released by the inserting of a coded card scanned in the lock, and carried out by means of a key, in particular for use in safety deposit boxes or compartments of public swimming pools or the like with an outwardly open card insertion shaft on the casing of the lock. For the purpose of obtaining a lock design that is easy to use and that excludes operating errors and which is safely protected against misuse, a locking repeat barrier is utilized that is associated with the bolt and actuated by the locking movement of the bolt even with the card inserted in the lock.
