try this,
step 1.) make sure that all windows and doors are closed (not locked)
step 2.) insert ignition key and turn from the off position to on position (do not crank engine) 6 times within 10 seconds. your key should be in the off position, when you have finished this procedure the hazard warning lights will flash twice to indicate that car is in programming mode.
step 3.) REMOVE the ignition key, press and hold the "UNLOCK" button, whilst still pressing the unlock button, press the "LOCK" button 3 times, then release the "UNLOCK" button and release the lock button. You will see the "FLASH ONCE" from the hazard warning lights, if not try step 3 again slowly!
notice*** if you have another fob to program then just follow step 3 only!!!... you can have upto 4 fobs programmed.
Step 4.) re-insert your ignition key and turn to the "ON" posistion, hazards should flash twice to represent programming finshed etc.
Step 5.) CHECK that your fob/s unlock and lock the doors etc
Thats it
