Convenient locking in the entire house

Where is the garage key?  Who has seen the key to the letter box?  The quest for the right key is everyday routine in many families.  But if you prefer to keep all the keys on one ring, you will have to carry quite a load.  After all, an adult family member on average uses five to ten if not more different keys every day.  So your bunch of keys will be heavy and bulky, almost too much for the pocket of your trousers or your coat but definitely too heavy for the ignition lock of your car.  Yet today there is a better, more convenient and more secure solution to these problems: one key for all!  With CES security cylinders you can equip an entire house so that virtually all doors can be opened with one and the same key.

Just think of the entrance door, the garage, the garden door, the door of a shed, the basement entrance door, any interior door, the letter box and if you like even furniture.  This not only dramatically reduces the number of keys required, it also ensures that you always have the right key at hand.

Since the dimensions of the door lock match those of the cylinder, tenants and owners can easily retrofit this single-key system at their doors.  So with just a little effort, you can make locking around the house significantly more convenient.  Better still: these state-of-the-art cylinders are also much more secure.

For example, modern locking cylinders feature an "emergency function" and can thus be locked and unlocked on either side.  This means that the door can also be opened if a key is inserted inside, so you do not have to worry that your children or other people in need of help are locked in.

High-quality cylinders will also comply with the demanding requirements of national standards such as the German DIN and the strict conditions imposed by the insurance companies.  The integrated anti-drilling and anti-pulling features (certified by the VdS, the accredited certification institution of the German Insurance Association) offer additional protection against burglars.

A key argument: Each cylinder is unique, is registered at the factory and is supplied together with a security card.  Duplicate keys can only be ordered against presentation of this security card so that the risk of unauthorized key copies is excluded.
