Call a flat bed, leave your key and key fob with the car, tell Jaguar(or some locksmiths do this service), you removed the battery and the key you have will not shut the alarm off, and needs to be programmed back onto the system.

 

The exciter ring reads the chip that is located in the key that was programmed to start the car. If you have more than one key I would recommend that you try them all. If all the keys fail to start the car then I would first check the exciter ring. The exciter ring is mounted around the ignition key cylinder and can be checked by using an ohm meter and measure the resistance to 30 to 35 ohms.

It is also mentioned in my No Start procedure on my page.

 

Hi Dennis07, thanks for clarifying the key color question.

I too agree there is an issue about the key not recognized, however is the issue the key or something else?
Jaguar quoted $157 to reprogram plus towing, then if thats not it i would be stuck with the car there and possibly paying for them to experiment further or paying to tow it back.

someone suggested I rub the key on the battery neg post, would that mess up the key code?

The car battery is what went low so the key should be fine.

Thank you, much appreciated,
Sid

 

Hi aode06, good thing that this can be done by other than Jaguar dealers.
I just called one locksmith who told me he can come to me to do it for $145.

I will shop it around to find out what the average cost is.

Thank you, much appreciated,
Sid

 

I would hate to go through this again due to another possible battery removal and reinstall or replacement, especially if/when away from home.

Is there any way to circumvent this part of the security system?

Thank you
Sid

 

I found a website that sells Jag keys and states the key is precloned.
Does that mean that all 99 xk8 keys have the same transponder code and that only the ingnition/key teeth patterns are different?

The key ad:

Works on the Following Models:
Jaguar XJ8 1998-1999
Jaguar XJR 1998-1999
Jaguar XK8 1997-1999
Jaguar XKR 1997-1999

Replaces the Following Key Types:
JMA TP05JAU.1.P
Ilco TBE1T5
HNA-7230AA1

Reusable: Yes

Cloneable: Yes

Chip: Pre-Cloned T5 (Megamos 13)

Test Key: Tibbe 8-Cut


Thank you,
Sid

 

Sid,

I think there has to be more to it than this, otherwise everybody's key would start everybody else's car if the teeth were made to align.

 

Hi Dennis07, I agree, but you read my question too quickly .

My question was/is;

Does that mean that all 99 xk8 keys have the same transponder code

and that only the ingnition/key teeth patterns are different?


Thanks again,
Sid

 

Good luck brother!

 

Sid,

I got it about the teeth pattern, but it seems unlikely to me they'd use the same chip + same coding in all cars, and count only on teeth pattern to keep key "A" from working in car "B".

 

So they can rip us off hundreds of $$$ per occurence, per customer, for reprogramming or for immobilize resets.

Thank you,
Sid

 

Sid,

Hey, two quick thoughts:

What happened to you here would not normally occur because of a battery removal, so with a little luck this should be a one-time event. WhiteXKR posted a few days back that the data may have been lost as part of a jump-starting attempt. When you get back in business, there are procedures to minimize the risks should you ever need to jump the car again. Better not to if you can avoid it.

The locksmith will come to you, correct? Sounds like the way to go since then no flatbed required. You'll know immediately if he got it fixed before opening your wallet.

Hang in there ...

 

If that were true, there would be no reason to require key programming. Every key having the same transponder code is functionally identical to no key having a transponder code.

 

Unless that car key person, that will come to you, is a very rich key guy, the only people I know of who can program a key to your car are the Jaguar dealers. However, he may be a former Jaguar employee who "borrowed" the dealer's. equipment ;-).
Just beware.

this is an example, you do not need jaguar lol.


If your key is lost by the security module,as to why this may of happened, the only explanation is that Jaguar techs explained, they have modules do things like this all the time with a drained /or shorted battery.

 

aode06,
Well that shoots my two cents above in the foot. But, no mention of what these people charge to do these key procedures. I (sort of) timed the video's and except the one where the guy goes away and comes back, the procedure lasted may be 3 min. That would have saved me a 300 mile round trip and about 300 bucks if I could find one of these guys.

My 97 xk8 does not have a chip in the key. Is everyone positive the other early cars have chips?

 

I am not positive but I think it was installed in the MY 1999.

 

Is that correct ??
Mine is a 1997 (UK) car and I'm pretty sure it has a "transponder" in the key. Not a great photo, but you can see a small circular "plug" on the side of the key which is where the transponder is inserted.
