I bought a used 1999 Jag XJ8 V8. I've had a couple of weeks now and no problems. But, I went out to get in it. I used the black key to unlock the doors and the alarm went off when I opened the door. I closed the door and locked it back up. After about 2 minutes the alarm turned itself off. This sequence of events happened 3 times. I do not have the green key. This has never happened before and I don't remember doing anything different. The only thing I did today was replace the electric anntena. Not the motor, just the anntena.
have the same problem?
