Your key might need reprogramming to the central locking ECU or it might be a blown fuse or module.

you should check the age of your battery (by the knock-off labels on the top of your battery)...and when you get a new one be sure to "refresh" the ground connection of the 1/0 black battery cable to ground with a coarse wirebrush...before putting it back together~ NEW battery with reNEWed ground should make your problems vanish~...tada~
