This is really helpful, when you replace the rear sparewheel well fuse box is it plugged, or did you have to rejoin every wire individually? Did it take long? Did you just do one wire at a time matching the wire colours? Sorry for all the questions, your the first person I've found to correct the problem. Kindest regards, Steve.

Hi guys. Have you found a solution for this? I'm in exactly the same situation. Jaguar main dealer in Basingstoke verified that the keyfobs are indeed perfectly fine and immersing a signal correctly. After two hours testing and diagnosing they confirmed that there are no faulty modules on the vehicle. Just the the door module goes offline after between 30 & 40 minutes. Suggesting a permanent live failure. This they said would initially require a technician to go through the wiring loom looking for any obvious defects. Move done this myself and can't see anything obvious. So I asked them can you not run a new permanent live to the module to see if that works? (There's 3 din plugs on the door module, which controls the Windows, mirrors aswell as the keyless entry. God knows which one is the perminant live. I'm currently studying a document I found on google which apparently contains the whole wiring diagram of my 2003 s type. Its a 3.0ltr auto sport and I've ran out of ideas. Although I have found a way in without setting the alarm off. (As this fault doesn't allow you to open the door and put the key in the ignition before the siren sounds) has anyone got any ideas or has anyone solved this mystery. Everything else works on the car perfectly. Kindest regards, Steve.

Hi Danny, Did you have any joy in solving this issue? I have a similar issue, where by I cant unlock the car with the key fobs and as soon as I unlock the door with a key and open it the alarm sounds immediately. There is no grace period of 10 seconds to get the key into the ignition to stop the alarm its instant. Now here's the freaky bit....... As soon as the key has been in the ignition and stops the alarm, the key fobs both work again. I've tried a new door module, but this doesn't stop this happening. When I lock the car either with the key or remote the alarm automatically sets, and as long as I return in under about 30mins I can still unlock the car with the key fobs. Any longer and I'm back to square one. I've replaced the battery in both the fobs and the car. Hope to hear back, Steve.
