The right key system for every property

Whatever the demands of the property, CES supplies the right key system. All CES key section series enjoy patent protection and comply with the highest DIN/EN requirements. The most recent product available from CES is the vertical reversible key system WD. WD is particularly user-friendly and offers superior technical protection against unauthorized key copying thanks to undercut technology and numerous active locking elements.
 
Also based on the undercut technology is the conventional key system DU.
 
By the way: we supply smaller locking systems up to 100 cylinders within 48 hours.
