ASSA CLIQ cylinders are based on ASSA dp mechanical cylinder platform. Combines a CLIQ electromechanical element with an ASSA dp cylinder. The dp 4400 cylinders offer extremely high security and full resistance to any currently known method of picking.


  • The dp cylinders are based on ASSA's well established Twin technology but features new innovative designs on the side bar mechanism.
  • Incorporate electronics that will read the electronic code of the key and if this matches, it will operate a small electric motor in the cylinder which will allow access.
  • Tested to BS EN 1303.
  • CLIQ cylinders can be specified for padlocks as well as industrial locking cylinders.

System includes:

dp series cylinder, electromechanical element, CLIQ keys (user, master control, [control key as required] and contact key). Programming device and software.
