  • pump locks by their sequence of operation which comprises three steps: a step of introducing the key to the stop on a rotor of the lock, then a step where the operator axially pushes the key and the rotor and finally a step of rotation of the key and the rotor which drives a latch.
  • the adequacy of the key to the lock is verified in particular when the key and the rotor are pushed axially.
  • the pump locks provide better reliability. Indeed, the verification of the coding is done while the key is in mechanical stop frank with the rotor. This allows better mechanical accuracy.
  • the keys of the pump locks are characterized in particular by the fact that the coding of the key is done by machining shapes at a predetermined axial distance from the mechanical stop of the key on the rotor.

  • a flat key has at its end a set of alternating teeth and grooves arranged to come into contact and abut against the end of the respective grooves.
  • the document describes a key containing a housing with an axially slidable element, to protect the key against fraudulent copies. Such a solution increases the cost of the key.
  • the invention proposes a lock of the pump and groove type and an associated key which have an additional safety means that is both cheap and does not generate an increase in the size of the lock.
  • the associated key is compatible with locks not presenting the additional security means.
