I have a jaguar 2.5l awd - cannot lock the doors by using the key fob i have to put the key in the door and lock them manually, however the key will open them by pressing the key fob anybody got ideas ??

sounds like one of the switches has failed on the drivers door latch that means a new latch unit is needed or it may be the drivers door module has failed more than likely the latch

you may have the battery in backwards

put ignition in off pos, switch on and off 4 times quickly, you will hear a chime then press a button on the fob this should reprogramme the fob.

if your just programming the fob to the module and it has not been replaced and your just needing a manual reset,then follow the folowing procedure:

1 Insert key into ignition
2 Turn key to 'I"
3 Turn key "II" and back to 'I' quickly 4 times
4 Alarm system will chime once when key is back to 'I' for the
fourth time
5 Remove key from ignition
6 Press any button on each key fob and alarm system will chime
for each fob if it has been programmed correctly
7 Press unlock/lock/trunk etc to make sure everything works

Sorry to hear this. The keys - if correct for the car will open the door manually with no need for electrical assistance. If the fob fails the correct action to take is to open the door manually with the key and immediately put the key in the ignition and start the car. If you open the door manually you will hear a chime - this is counting down to sounding the alarm as it knows the door has been opened but not with the fob which is used to reset the alarm. It may be that the car has not been opened with the key for many years and the door locks are corroded - try spraying WD40 into the locks and work them with the key. Failing all the above - its call the Mechs time.
Hope this helps - good luck.

Its propably the door courtesy switch. Remove it, clean the wire and contacts and try that. Hope that helps

you may have a bad door switch, theres a switch on the drivers door lock, when door is unlocked with fob or key the switch is activeated to shut alarm down,the lock moves to hit switch with key or fob,so if the switch is bad it will not shut down alarm, i would start there,door panel has to be remove,then latch has to be remove to get to switch, then test with a meter see if it opens and closes the connection, hope this helps.

This does not sound like a fob fault - but a locking control module fault , either in the hardware or software of the unit. Get it checked at a Jaguar dealers. When unlocking using the key - as soon as the door is opened you should hear a chime sounding inside the car - this is a timer counting down to sounding the alarm. If you put your key in the ignition as soon as you open the door the alarm should not go off and the chime should stop. If it does not this again points to a fault in the locking controller.
hope this helps - good luck.

Your key fob needs reprogramming, and yes the alarm will go off when you open the door, but you have enough time to put the key in the ignition which will prevent the alarm sounding. Car is usable until you get the fob sorted by locking and unlocking using the key.

I have an A4 and did this to re-program my key:

1. used the key to start the car...then turned it off
2. put the key in the driver door (door closed)
3. pressed the lock button on the key fob once
4. turned the key to lock the door.

This is basically the steps in the owners manual, but the car must be started with the key first, and the key must be in the door lock before pressing the lock button.
