here are the better directions....
sit in car, close door.
1) put key in ignition and turn it so all lights come on but dont start the car!
2) turn off and remove the key (do this within a second)
3) hold down the lock button and press unlock 3 times (do this within 2 seconds of removing from the car)
4) sit there for a second then it should lock and unlock itself.
5) get out close door walk away.... and dont forget to lock it
if that does not work, make sure that the LED is flashing if it is not then its time for a new fob off ebay.
