2p04 jaguar xtype security system locks up on me while I'm driving down the road. Car just shuts off and starts beeping. It did this to me once before but it was when it was parked and I just unhooked the battery and hooked it back up in a few minutes. This time tho Its not working I've left it unhooked for 30 mins and nothing. Every time I try to start it the security system just keeps beeping and nothing will come on. I don't have a key fob all I have is a replacement key with the chip in it and. I've tried arming the alarm by locking the doors and unarming it and nothing it just keeps beeping. What can I do?? I'm waiting on a tow truck now

 

Chris, sounds like the solder joints on the back side of the instrument cluster have broken and those will most likely need to be resoldered to correct the issue. Otherwise, without more information, you are going to need a higher end code reader so you can access the U-codes to see what modules are having issues so you can access the security codes and see what the car is not liking.

 

is there anyway to disarm the security system?

 

Chris, unfortunately, no there is not. It was designed around not being able to bypass it. In short, the instrument cluster looks for the chip in the key and sends a "good to go" message when it finds an approved key. If the instrument cluster does not see this, then no message is sent and the ECU will not send the necessary information to power the fuel injectors and coils.
