Institutional key control that acts as a mechanical sign-out sheet when active is available through sequence locks from ETI Products. The sequence lock consists of two keys. The first key is a user key, assigned to an individual. The second key, which is released by the user key, then has access to the controlled lock. When the controlled key is released, the user key is retained until the controlled key is replaced. The sequence retaining device establishes accountability for master keys, emergency bypass keys, access control, safety lockout and other functions. Models are available for Small Format Best, Large Format Schlage and Key N Knob Cylinders.
