As said biggest load of garbage going, bought a car a couple of years ago with one, when I picked the car up(astra mk3) I lost the bloody key at the service station in the snow somewhere, mate was with me so had a few tools, took all of 2 minutes to bypass as so simple.
Take it out would be my advice as well, and get a nice CAT 1 .
alarm/immoby .

ps if you pull the CARD part out of the holder you will see the connection details so can just copy them for a quick job.
