Remote Key will not open or lock car after being driven

You may need to remove the back seats and try reaching in with a long rod/bar, and unlatch it.

I had the same problem in my 2002 not isn't back I got a tin of wd 40 put the straw applecateter in the key hole and give it a good dose after 10 minute it open did it again now it works fine so I did them soon to make shore try it before you have to pull the door panel apart

Replace the battery in the remote.

Do you smoke in the car? could be that the infra red sensor in the car (usually near the interior mirror) needs cleaning. I bought a Renault Scenic which had same problem, it would only unlock from very close to the car. After trying new battery in the remote I cleaned the sensor and never had any more problems. PS I assume you've tried a new remote battery?

check lock buttons on doors and keyfob for stuck button

It may not be the battery, it may be the ignition switch. There is a switch within the key barrel if this switch gets dirty the remote lock, I have a 2004 model. Squirt some WD40 into the key barrel and turn the key a few time to shift the dirt, then try the remote. The switch is design not to lock the doors accidently, so the switch has to closed, when you take the key out of the barrel.

Hi,

I have a similar problem in my x type. Although if I press unlock button on the key first and then use the metalic key to unlock it dissables the alarm.

Also according to the manual if you unlock by the metalic key the car starts a beeping sound its I think 15-20 second timer within which you should put the key and start the ignition (don't need to start the engin) this will dissarm the alarm if not the alarm will go off in 15-20 second.

Hope this information is of any use, am trying to get hold of Jaguar dealers to fix this issue. If you come accross any solution please do let me know too

hi,when you remove the key from the ignition,does the little flap in the barrell flip down?.if not the key fob wont work.it thinks the key is still in the barrell.after a tiny bit of wd40 on the key it was ok.it pickled me head for ages.maybe its that. paul

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.

Seperate key fobs only can be programmed in the following way.

Turn ignition on/off 8 x times (allow all functions to stabilise) after the 9th on - press a button on both remote fobs. then turn ign. off. use good remote to lock and then try new remote to unlock/lock. sometimes it works first time - sometimes you have to repeat actions. good luck.
