Karr Key Ignition cut system

Our 2000 Monaco Diplomat came with a device labeled Karr Key. Key looks like small stereo plug with mold key top. Key plugs into a jack that seems to be connected by four wires to three of the primary ignition wires. I do not have a wiring schematic for device. When I Google on Karr Key I get listings about Key Fob remotes so I suspect device is not made anymore.

Anyone have any information on this product? I'd like to remove from ignition system.

Thank you

Most such devices are simply ignition cut-outs. You can't start the vehicle without a plug (or similar device) in the jack, supposedly making the vehicle harder to steal.

Karr is now seems to be part of Southwest Dealer Services. The anti-theft ignition devices have fallen out of favor, but they may still be able to provide some tech help on the old system.

But I suspect you can figure it out on your own. The wires either interrupt the ignition circuit or ground it out unless the plug is in place. Study it for a bit and you will probably realize which technique is used and how to remove the Karr box from the circuit.

My 2000 Diplomat does not have a Karr Key. I suspect it was an added device.

Karr Key response

Gentlemen, thank you for taking the time to respond. Greg, thank you for locating Karr on web, I had looked high and low using Google without success. We just returned from 4 day trip in coach and I had used a bit of that time to pull the Karr system out from under the dash.
Interesting bunch of cheap trickery. The main white lead from ignition switch had been cut and the Karr system spliced into the white lead. Two other leads had 3m inline clips attached to two other ignition wires leading back to Karr. The Karr system was a small black box and and a buzzer. I could see what to disconnect and reconnect, but the installer had somehow crimped or crushed the connectors so tight I could not disconnect with fingers. Will attack this week with a couple of pairs of pliers to see if I can disconnect before cutting leads.
Very much appreciate the comments.
