Keying Options /Other/multlockCOM/Pics/For%20Business/999X435_Key.jpg Dedicated to satisfying customers’ needs, Mul-T-Lock offers many convenient keying options. These options range from traditional to innovative and are designed to offer convenience, control and peace of mind. Keyed Different This keying option simply means that each product in a system is operated by only its own individual keys. Three different locks, for example, could each be opened by only by 3 separate specific keys Keyed Alike This keying option allows for the operation of multiple doors with just a single key. Multiple products in a system can be keyed to the same locking combination allowing just one key to open all of them. Three different locks, for example, could each be opened by the same key. Master Keyed This keying option allows for highly specific levels of access for different key holders. Master key systems can dramatically reduce the amount of keys that must be distributed to users since rather than having to supply a different key for every door that a user has access to, the user can be given just one key that will allow them to access all doors, while another user may be given a separate key that operates only half as many doors. Three different locks, for example, may be master keyed so that one key opens all three doors, one key opens only two of the three doors and still a third key opens only one.

While under construction, one construction key operates all of the cylinders on the site. Then, when a tenant moves in, a special change key is inserted and turned, which alters key access, disallowing the construction master key and change key to ever work again and preparing the cylinder for operation by the user key only.
