Abstract
A locking device suitable for NID housing security. The device includes a slotted cylinder, a key and key tool. The slotted cylinder has a resistance component contained in the cylinder. The key is mateable with the slotted cylinder and is held in place by the force of the resistance component. The key head has a cavity therein of a complimentary shape to the key tool so that the tool may be used to turn the key for locking or unlocking. A cylindrical sleeve is used for additional security. The sleeve fits over the mated key and slotted cylinder to protect against release of the parts and may further provide a barrier to removal from a structure being locked. By use of different key head cavity shapes each subscriber may only access their own line in a NID.
