Jaguar Repair Problems? Ask a Jaguar Repairs Expert.
It is possible the remote itself is faulty. If the battery is new and installed properly then we may need a new remote. The problem is in order to reprogram yours or a new remote a Jag factory tool or equivalent is needed. Another possibility is the door module is bad which I have replaced a few for this. These modules also would need to be programmed if replaced. Sometimes disconnecting the negative battery terminal cable for about an hour then reconnecting it and unlocking the vehicle using the key in the driver door may reset the module. Let me know.
