Hi,

I recently bought a 2002 x-type 2.5. Came with a key fob with no batteries in it, so I got it a new battery but it won't work.

I then tried to reprogramme it by turning the key from I to II 4 times and what not, heard the chime, tried the buttons, don't work.

Any advice?

Thanks

 

Did you follow all the steps here

I had the same issue, my car came with two fobs; one worked and the other one didn't at all. I tried new batteries in both; no change. I then tried reprogramming as instructed (used the working key for the first part obviously), but no beeps resulted when I went through every single button on the bad fob.

I then took both fobs apart, tested both circuit boards with both battery units, and each time with each combination they just worked (without reprogramming!). They've worked ever since. I've no idea what was caused the problem, but you might want to try something similar.

 

Right, I closed my door. I will try again soon! Thanks for the tip

 

Cheers for the reply, I only have one set of keys that's the problem. The annoying thing is that I don't know whether the circuit boards are working haha.

 

By "one set of keys" do you mean you have just one key fob? To my knowledge, you need to do the first steps in the reprogramming (the ignition part) with a working key, and after the chime you press the buttons on the key fob that you want to "pair" with the car.

If you have just one key fob and it doesn't work, I think you need help from the dealer. It would be pretty horrible security-wise if you could just take a random X-Type key and pair it with a random unlocked X-Type

 

You only need 1 key to pair the remote opening to the car. You need 2 to program the immobilisation part of the key.
If you are hearing the chime then the GEM on the car is ok. The remote part of your key must be faulty. You can buy them cheaply and swap the keyblade part of your original key (that holds the immobilisation code) onto the new fob.

 

Jaguar has info for the keyfob faults

Hello there! one of my brother had the same problem, he found out he was missing one step on the programming steps i guess..he posted it here Programming Jaguar key fob you might want to check it out, some people gave some really good advices there as well. it might help you out! cheers!

 

When I bought my '05 X-Type in '08 I asked the dealer if I could get a key that could just open the trunk where I store my motorcycle gear during the riding season. I didn't want the whole fob assembly since I needed to have it on my motorcycle key ring and didn't want a lot extra "stuff" that would make the ring bulky.

The dealer supplied me with a key without the battery and buttons (i.e., just the part of the fob with the switch-blade key) that fits the lock and opens doors/trunk but won't start the car. I drilled a hole in the end to mount it on the key ring.

Does that mean that they didn't program it to activate the ignition but only to physically work in the door?

Could I program that key so that it would start the engine? Or would trying to do that possibly screw up the two other complete key fobs that I have?

Try the 4 on off thing with the door open. Mine works with the door open but not when it's closed.

 

I have the same problem, did the key reprogramming thing, got the GEM ding, but fob still doesn't work. Is there any way to test the circuits? Next stop is Jag dealer, but don't want to spend big money.

Edit:
Went to dealer and checked circuit board in key fob, it is giving off a signal, so what else could it be??? Dealer said they charge $123 to reprogram key.
