Mechanical locking systems
How do I maintain my mechanical locking cylinders adequately?
To maintain a high functionality and long service life, mechanical locking cylinders should regularly (every 6 months) be treated with the CES care spray. Please do not use any other agents! Never lubricate with oil, graphite or agents containing resin!
The spray is available at the security and lock dealers, or you order it from us. Simply tell us the registration number of your locking cylinder. You find it on your key and on your security card.
