Abstract
A device for preventing unauthorized access to female modular telephone jacks. A physical plug has been designed such that when it is inserted into an RJ-11, RJ-14, or RJ-45 modular telephone jack, it locks into place and cannot be removed without the use of a specialized tool. The specialized tool then acts as a key to unlock the plug. Several different pairs of plugs and corresponding tools have been created such that there are different `locks` and `keys`.
