I have a 2003 S type R and my 2 Key Fobs no longer work. This was after the mechanic worked on my car, disconnected the battery, however it was for a very brief time (so he told me) since the radio did not need to be reset with the security code and did not loose any of the preset station settings.

I tried several methods found on this forum such as in the X type forum and others but none worked.

I also tried others that I found on a Google search but did not work.

My questions are:

1. Is there a fuse that handles the key fob receiver only, I looked in the manual but could not find one specific to the key fob receiver. By the way I did replace the CR2032 battery in the key fob.
2. Is the procedure for a 2003 S-T-R different.
3. Where is the receiver located on the car so I can see if the connector came loose. Is that a possibility or is the key fob transmitter incorporated with other functions.
4. Is there a way to test that the receiver is working?

I would hope that some of the experts on this forum can help me before my only option is the Jaguar dealer and a fee of over $200.

Thanks for any help given in advance.

 

That's very strange. I know on Audi's you put the key in the door and hold it in the locked/unlocked position while pressing the button. What kind of work was he doing on the car? Nothing that involved welding?

 

I had a bad Mass Air Sensor and the mechanic replaced it and then wanted to clear a number of codes caused by the bad MAS which caused miss firing codes. So he disconnected the battery for a very brief time since nothing else was reset.

 

Well the fact that he disconnected the battery means he had no idea what he was doing. You can't reset any codes or CELs on a Jaguar by disconnecting the battery. Thats a trick from back in the 80's. You need a hand-held scanner at a minimum. You may just have to take the car to the dealer and pay the 1 hour diagnosis fee so they can reprogram the key with the IDS computer. Or just give your service writer or tech a bottle of whiskey and ask nicely.

Does your key still start the car or will the immobilizer not let you?

 

Both key fobs worked before you went to the dealer? Now, immediately after the dealer worked on the car the fobs don't work? Sounds like the dealer owes you a re-progamming and an apology.

Oh yea.. I'm going to back feed current through a car riddled with electronic modules.... BTW, read the post! He replaced the batteries already..
Gotta Go... I'm hungry for some frog legs!

 

obviously someone doesn't know that the cigarette outlets are IGNITION controlled. I wouldn't advise this at all. You will be putting 9v into the accessory circuit, not the battery circuit. Good luck with that

 

Look at the above quote, really ?????? SOME volts???

Stop now before you ruin someones car that doesn't understand what they are doing.

 

danielsatur - I've never posted this in any forum before, but:

please stop posting unless you're going to read up on the context and behave responsibly.

 

To answer some of the points, the mechanic did use a code reader and deleted the miss firing codes that way I assume. I installed new CR2032 in both Key FOB's and still did not work. Also if the battery was disconnected for a very short time since the car radio remained programmed why would the key fobs loose the programming.

I would still like to find out for sure that the only was to re-program the key fobs on a 2003 STR is by a dealer or is there another way?

 

Toller - I did not use a Jaguar dealer since the last time I took my car there for a code they wanted $900 to replace a knock sensor and when I told them forget it, the code was gone and the car ran great (i found out that sometimes when you get bad gas you can get that code but running the car for a while will get rid of the code). I would rather not say the dealers name, but I will never go there again. I'll just mention that the dealership in on the South Shore of Nassau County on Long Island NY.

 

Danielsatur - I have a code reader and the mechanic I use is very good and not just cleared the codes but repaired the problem. Of course the key fobs now don't work but he stands by the fact that all the work he did on the car could not have caused the key fobs to no longer work.

So I'm trying to find out if anyone on this forum had a similar problem and how they solved it.

 

The radio still working doesn't mean anything. I disconnect my battery all the time for at least an hour and have never had to do anything to get the radio back on and all of the stations are still set. It sounds like something with the receiver unit in the car not the remotes. For both lose programming at the same time is strange.

 

Gessie - I understand you have to change the fob battery quickly or else the fob goes out of sync with the car. Also, it's fairly easy to short out the battery in some way - there's a TSB about it: S527, it's in the stickies either here or on www.jaguarforum.co.uk

You can't reprogram the fobs yourself. A good auto electrician may be able to but check with care as it needs specialist electronic gear. There are posts here or on the UK forum about this if you search.

 

Gessie, I've changed the batteries on both fobs on my 05 and never had an issue but jagv8 may be on the right track. I would take this as an opportunity to find another dealer. Since you hail from the Long Island area, you should be able to find one fairly close. I personally would explain your "fear" of going to the dealer to a service adviser and see how they react. Don't bash the other dealer by name but tell them what happened. The ones that are understanding and want to help would be the ones I take my car to. I happen to have a really good dealer in Cleveland. So good that the competing dealership in the Cleveland area sent out coupons to Jaguar Cleveland's customers telling them they were under new management... Hmmmm.... So, don't loose faith in the dealer network, you may be pleasantly surprised. BTW.. I threw out the coupons..Sometimes saving a penny ends up costing $$$$.

 

JagV8 & JOsworth - thanks for the information and advice. Regarding the received is it a stand alone unit or incorporated into other functions. I can't find it in the manual.
