2003 S-t-R Key FOB problem
#1
![Unhappy](https://www.jaguarforums.com/forum/images/icons/icon9.gif)
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.

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?

You can buy a 9volt battery and cigar lighter connetor @ any local Auto parts store to back-feed 9-volts through cigar lighter outlet to save codes.
Test or buy new Key FOB batterys for all key FOB's @ a local parts store, and have a local Jag service reprogram all at once.
I would consider buying all new batteries for Key FOB's,because of age.

Had to Jack-up a Jag, and back-feed 12volts through the starter to get into the
car, because the owner locked keys in the car with a dead battery in trunk.
WTF-
8-12VOLTS DC is enough to save static data in control modules.
Just befor your 12volt battery go's bad, it isn't 12volts dc.
Buy a new battery and everything fine.
Consider a Solar trickle charger for an RV, if your car is parked for a week.
True - Some cigar outlets go through the key switch Acc, and some not.
Check cigar outlet for some volts without key.

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.

1) Pull code at a local parts store for free next time.
Example:
Do a Goggle ''Troubleshoot JAG P0420 & p0430''
Even though the code is cleared, it probably will throw another code within the next drive cycle.
Get a guaratee for a part replacement, that the car isn't going throw the same code in the next drive cycle.
Call a good local backyard Auto Tech for a reprogram, I had it done for $30.
Some control modules will loose memory data in static memory, the enable bit might be lost on the Key receiver.
Back feeding 12v to save memory in the ECU,PCU, and Control modules is nothing new.
You really don't want to loose drive cycle data and faliures during battery replacement.
The customer might get mad, if the driver lost his seat memory too!

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 $$$$.
