Maintenance instructions

Depending on frequency of use and where the product is stored, it is important to put a few drops of fine lube in the lock to prevent the mechanism from jamming. You must lubricate your lock at least twice a year.

Ideally, use graphite powder or a fine lube that flows easily and is non-greasy, such as our Pro Dry Lube. Avoid using cleaning agents containing solvents as they will attack the plastic and may damage the product. Lube can be deposited directly inside or on the key: operate the cylinder and locking mechanism to spread the lube.
Regularly check the operation of all the keys supplied with the product.
