Try reprogramming your key remote first, get in the car close the drivers door, turn on the ignition till the dash lights are on but don't start the engine, press the remote buttons open close open close, if this has worked you should hear clunk clunk, and the doors should lock and open once by themselves, turn off the ignition and remove the key before opening the door, if that doesn't work you open the key by inserting a flat bladed screwdriver between the blade and case in the rectangular notch on the side without the buttons at the forward end nearest the blate, twist the screwdriver and the blade with its C shaped plastic frame should come off the remote, if the key has no notch then hold the remote in one hand and the remote by the front and back, then rock the parts back and forward till it pulls off, then gently pull the 2 halves of the remote apart (seperate the front from the back, be careful taking the battery out as the terminals on the tray are a little feeble, refitting is the reverse of removal, then program the key again. Hope this helps.
