2000 jaguar - the remote went dead. I got a new battery and I know I have to get that reprogrammed in order to use. My problem is that I can't use the key to lock the doors or trunk. when I lock it with the keys, it will lock but immediately unlocks and I am not able to use the key to open the trunk.

  • The Jaguar handbook indicated that the FOB does need to be reprogramed. The remote does nothing(will not open or lock doors)until I get it reprogramed. I guess my question is how come the key won't work to lock the doors or open the trunk. Commented Jan 21, 2016 at 1:43

There are some vehicles that require a FOB reprogram if the battery is not replaces according to a procedure

Some manufacturers have a battery replacement procedure so key fobs, stereos and clocks do not have to be reset after the replacemnt.

I can not validate a 2000 Jaguar but I can say a 2013 Jaguar (yahg-u-r) does require a process driven battery replacement to prevent key fob reprogramming.

If you call a local locksmith, they will probably know if you need a reprogram or not.

  • I have been reading the threads and know what I need to do to get the FOB reprogramed. Thanks for your help. Commented Jan 21, 2016 at 19:36

Are you sure it's the fob? First, I don't believe you need to get the remote programmed for a battery change ... most cars are not this way. Second, when the locks pop back up, this is usually due to one of the doors being ajar. Could also be the trunk lid or the hood. Before you assume it's the remote (sounds like it's actually working to me or you'd get nothing), ensure all of the doors/trunk/hood are shut tight.
