My remote will not open my 1998 XJ8 Jaguar....my key will not open the door...why?

I'm having a similar issue to the one described in this post:

http://www.2carpros.com/questions/jaguar-xj8-1998-jaguar-xj8-car-turns-over-then-stalls

However, I can not find an inertia switch. I have a 1998 Jaguar XK8 convertible. Does being a convertible make a difference in this switch's location?
I removed the passenger kick panel and also checked in the fuse box door on the dash at the passenger side. Thank you.

Aug. 12, 2015 - I twisted out the socket in order to swap out the bulb but that wasn't happening. The bulbs are the kind the slide into the connectors so it should ... Missing: drivers ‎' Must include: drivers

Security is set. Could be one problem. Fuel system can do this, but rarely. Takes a scanner to see where to look first.

You will need to have the car towed to a Jaguar dealer to fix it.

Just bought my 98 a week ago....from what I can figure out....the valet mode disables the inside button....until the trunk is opened by the key. From what I understand also....there is a valet key....and an owner key. (I saw the differences online this week) which also ties in with valet mode.

the fob should come apart in two pieces front and back look for a indent on the seam os the two parts if you find one a flat head screw driver will do the job put it in the indent and twist do not pry twist

This is the procedure from the service manaul:

JAGUAR
XJ8 Remote Control Programming
1. Unlock the Boot/trunk with key.
2. Turn Ignition on.
3. Warning light on dash comes on.
4. When they go out, lift arm rest, inside their is a valley button, Press 5 times within 5 secs of lights on dash going out, Horn & Lights Flash.
5. Press any button on remote, remote programmed.

i know when i programed my XJ8... i had to use the sender button on the actual opener mounted on the garage roof and not the hand-held remote... not sure if that helps

Try re-programming the remotes, here is the procedure for your car.

I know what the problem is but never tried to resolve it. I have a 1998 XJ8 and went through the same problem. After numerous attempts to program the 4 channel built in opener I researched the problem and learned that the system in the car actually changes the code after every use. It's a security feature built in to the system. I simply started keeping my remote in the car.

There must be a way to disable the automatic randomizer so it retains the code from your remote opener everytime. Check with the dealer to see if it can be disabled and you will be in business. Please post the info if you get it.

Good Luck!
