99 came with 2 Fobs. One worked the other not. PO said battery dead so changed both and now neither works? Do they have to be re-programmed or something when batteries changed?

 

I guess you are discussing a 1999 X100? (not the S-Type 4.0 Sport, 2000 in your signature)
So what if they need to be configured?? There is no limit as to how many times it can be done.

It takes a few minutes to do this in the X100 or X308.

 

Yes, 1999 XK8. How do you configure them?

 

A forum member documented the procedure as a .pdf for the X100/X308/X400.

 

Three years ago I had to modify the instructions referenced below to get my new 2nd FOB to work correctly. It’s still working perfectly.

Previous post copied below:


I added these instructions to the 1st post by JimC64 and together this is how it read to me:

"......
1996-06 XK8/R cars:

1. Insert ignition key into the ignition switch barrel, but do not turn it.
2. Hold the turn signal switch stalk in the "flash to pass" postion and turn the ignition on with the key (while holding the turn signal switch in "flash to pass").
3. Then repeatedly flash the lights with the turn signal stalk until a confirmation chirp is heard (usually five or six flashes).
4. After hearing the chirp, depress the button on the remote transmitter being programmed. If the remote was accepted, there will be another confirmation chirp.

5. Turn off the ignition and test the remote.

Might also be worth editing the XK8/XKR instructions to say that the procedure has to be repeated 5 times.
ie: if you have 2 remotes, programme the 2nd remote 4 times, to make a total of 5 programming procedures, as you do with the other Jaguar models.

Also, all remotes should be reprogrammed whenever any remote is reprogrammed.
......"

I got NOWHERE using this sequence in trying to program two remotes, (let's call them remote "A" and remote "B"), when programming remote "A" one time , then programming remote "B" four times, as suggested above.

out of desperation I tried doing both remotes together like this:

followed the first 3 steps unaltered:

1. Insert ignition key into the ignition switch barrel, but do not turn it.
2. Hold the turn signal switch stalk in the "flash to pass" postion and turn the ignition on with the key (while holding the turn signal switch in "flash to pass").
3. Then repeatedly flash the lights with the turn signal stalk until a confirmation chirp is heard (usually five or six flashes).

This is my STEP 4:

4. After hearing the chirp, depress the button on the remote transmitter "A" being programmed. If the remote was accepted, there will be another confirmation chirp. THEN immediately depress the button on the remote transmitter "B" being programmed. If the remote was accepted, there will be another confirmation chirp.

Repeated those steps 1-4 five times, and both remotes "A" and B" were now programmed.

Is my experience unique ? Or universal ?

I have never had to repeat 5 times.
The keyfob transmitters (if the SLCM accepts) are configured if the audible 'chirp' (or security light in selector lever illumination module) verifies.

I have witnessed the SLCM not accepting the keyfob transmitters if the SLCM was 'full' with 5 different transmitters.
The SLCM can be ERASED (CLEAR ALL KEYFOB TRANSMITTERS) with WDS or IDS.

I needed to do the CLEAR ALL KEYFOB TRANSMITTERS a few times in my career. A simple process in the SETUP AND CONFIGURATION tab.

Then the SLCM accepted the keyfob transmitters normally.

 

I only repeated the steps multiple times based on posts on this forum directing to do so. It did seem to be a little hocus-pocus.
