"..locks cycle twice.."I purchased an additional FOB after losing one in an emergency room visit. Verified that the FCC ID matches. And went through the procedure to register the FOB. I am certain that I am performing the procedure right, as I get the appropriate confirmation lock unlock response from the highlander. Even if I do Add or rewrite mode, when I go to press both the lock and unlock button simultaneously on the fob and then press the lock button, the door locks cycle twice indicating the the FOB was not accepted. Not sure what else to do here...
I have performed the procedure so many times I can enter programming without reading the instructions.
No key in the ignition and from OUTSIDE...??
