Hey guys,

I have started looking into this as my car has only one remaining keyfob. It is not on the top of the list as yet as I want to finish the build.... But it will always be in the back of my mind if I do not get onto it at some point.

Car is a '98 4.0 Limited and the PCM has the code P56041 278AD. I keep having a look on Ebay and there are plenty with codes that match the first section but not completely. I can't seem to locate the info to translate the code and I do not know how critical a complete match is. I understand the vast majority of US cars had the NP231 transfer case where mine is the 242.

I am not fussed on having the central locking or keyfob at all I just want rid of the damn potential nightmare that is the M&S immobiliser. The remaining fob will eventually get wet, crushed or lost and I will end up stuck somewhere. Besides I find the disarming process annoying anyway..

Anyone done this or know a little more than me? Cheers..

The remote keyfob doesn't operate the immobiliser on a '98 XJ anyway.

Cheers Mike,

Maybe it's a '97 then, does that make the difference? R reg anyhow so one of the two It has the twin button keyfob and simple (probably not chipped) black keys. It flashes security on the dash if you dont click the keyfob and I am guessing it will cut the engine after a few seconds but I have yet to test that. I just figured it was the one I had been reading up on. It is the facelift model
