Physically lockable network patch ports

Hi All,

I have a bit of a strange solution i'm looking for, as background our offices are almost exclusively Wifi based for network access and the only real need for physical ports is in IT where a hard wired connections are required for developers, etc. for the majority of these ports we have them locked down with port security as well as monitoring tools checking for invalid access in the event of mac spoofing. now our trouble is with our Service desk staff who require the ability to plug any computer into the ports at their desks for troubleshooting/imaging and as such port security simply wont work.

Essentially what i am looking for is a product that would introduce a level of physical security to these patch ports which would require a key to open the patch panel in order to connect a cable to the RJ-45. Ideally id like it so statically a single cable could leave the lockbox so they can remain locked at all times and if the connection needs to change, then they would unlock the port and connect a new cable.

Is anyone aware of anything like this being available on the market? i've done some looking and all i can find is cheap plastic port plugs that block the port until you go at them with a set of side cutters and that's not exactly secure in my opinion.

Thanks in advance for any insight all you fine people can provide.
