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 TDU with trademark protection. Beyond the protection afforded by a patent, a trademark offers an indefinite legal protection against unauthorized duplication of the original keys.
 
By the way: we supply smaller locking systems within 48 hours.
