Hello everyone,

I came to lost my keys on my xjr. Luckily I have a same year parts car with keys!

Question is, what do I have to swap over in order to make that key work.

I have already swapped the body control module and the ignition key tumbler. I tried turning it on after this but no ignition.

Much appreciated

 

Ups. I have a hunch, that this might be one of those things, which you cannot do yourself.
It is possible that a Jaguar dealer (or a very capable car-locksmith) has to connect a special programmer's unit to your car via the OBDII port to let the car know about the new ignition lock with the transponder-receiver to recognize the transponder signal in the key...

 

Find a dealer or indy who has the software to reprogram your keys (maybe your Body Control Module too -- hopefully the correct series). Depending on how big a city you live in in Mexico, maybe a very good locksmith. My local locksmith had the software and new keys and fobs and was able to reprogram the new key and the old.

 

From my understanding you could do this but it would require the donor cars instrament cluster, immobilier module, and keys correct?

 

The locksmith needs to have the software to program the actual key, it costs new about £6,000 and is only now available from China. So if you can find a guy with that software then good.
Lots of guys will tell you it’s only a Ford tibby key that needs to be cut. But the key also has a chip on it. I got a spare on mine done for 40 quid.

 

Being in Mexico, it may be difficult to find a Jaguar Dealer however,
there are a few. Once a dealership recognizes you actually own the
car (proof of ownership required), they can look up the tibbe key settings.
They may also have a blank that they can cut and program, although
that is usually expensive. If you can acquire a blank tibbe, you can use
the tibbe settings from the dealer to make a key for the existing equipment
and then have a locksmith (if available) program it to your car.

 

I think we are missing the question in the post.

@ncanales33 has a same year parts car and is asking what modules need to be swapped to allow the transponder key/fob they have from their parts car to work with and run their main car.

I know the immobilizer/security module in the trunk and the instrument pack are there any others?

 

Yeah, I saw that intention lothar. It just seems like a whole lot more
work to get the car working right going that route. Might save some
money though.

 

Get a key to fit the car; not mod the car to fit a key: come on . . .

 

Unless you take it to someone with the factory software I think you will need to exchange the ECU,TCU, ABS and probably some other modules.

 

Yeah it may be more sweat work but at the same time I would rather someone not junk a car or go without if they have the parts on hand and do not have the cash.

I saved a 2007 SLK350 with 114k that was going to have the cats cut off and scrapped because the ecu capacitors had leaked.

I bought the car and a donor ECU, EIS, EIL, and got with someone to wipe the drive auth from the 722.9 conductor plate to get the car running.

I the orginal owner didnt have the 5k that mercades wanted, and i didnt either. so for $300 in ebay parts and more work then just telling the dealker todo it the car is now running and driving.

I can share that when I bought the xjr I have I called ever land rover and jaghuar dealer in a 100 mile radius of my home and none would order a key or fob for me, or program a key or fob i brought them or cut a dumb key just to unlock the doors if the keys ended up locked inside.

So even the answer just get the dealer to do it is sometimes not an option because even if there is a dealer near you, you have the money to spend, and the means to get the car there they might not do it anyways.

 

I had the same issue: had one key and needed a second. A friend sells old cars, he checked with our local locksmiths until he found one with replacement keys and software: $250 later, fixed. Dealer was no help: 1. no longer available; 2. We don't support or service these old cars! The guy who helped me was Art Gedoyan at Hampton Roads Lock and Key 757 453 7072 or mobile 757 277 8666; a shot in the dark, he may have a replacement key or two for your vehicle and contacts in TN who may be able to help you.

Some indy in Nashville has the software package to repair these old jags. . . and can probably point you to a locksmith they use.
