The “No Mischief Key” is a simple replacement fit for the existing red/green indicator fitted to the face plate of most ALM indicator bolts. The signal can be supplied with a number of “keys” which are designed to be carried by authorised staff on a key ring.
When access is required, the key is simply fitted to the protruding spigot on the face plate and turned to release the lock.
