I tried the key initialization process several times but still does not work. Any ideas?
Not sure which intializing procedure you followed...there are multiple instructions out there...some of them are incorrect. Since we are not there when your reprogramming your keys...all I can suggest is that you follow the instructions below to a "T". You can NOT fudge, combine, skip, ignore any of the steps...if not failure will occur.

Also let us know if the red LED is illuminating...if it is barely illuminating or weakly illuminating...then the new batteries may have discharged while sitting on the shelf.

Make sure that:
  • you lock/unlock the car manually from outside
  • all doors are shut
  • turn ignition to POSITION 1 (position 2 or 3 may result in failure to program)
  • only insert the FIRST key...start the 2nd key on STEP 3 (with pushing the buttons etc)

HINT: KL R = ignition position 1
