My key fob has good battery (checked that out) but it will not lock door. Fuse problem? When you clicl on lock - it makes lights on drivers side blink but doesn't lock. When you hit unlock - it sounds like it is trying. Where is the fuse located that I might try changing that out?
Most likely is not a blown fuse because it is trying to work. Try to find the antenna instead as it maybe block from the signal. You did not say what year is the car.

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.

the " FOB ", is the part where the button for the alarm / entry control is......its basically another name for a " housing " ...and you are correct, they work from a small round flat battery
