Hey everyone I'm new here I've been looking at a lot of threads on this website and I can't seem to find the answer to my question. I recently bought a used 07 TL with 65000 miles on I love the car so far but I cannot seem to get the key fobs to link to the car. I assume both key fobs are aftermarkets due to the fact they do not say driver 1 or Driver 2 on the back nor do they have the Acura symbol. Both key fobs function just fine they unlock and lock doors. I have tried linking both fobs to the car by holding unlock and lock at the same time and I get no blink of the LED light. No matter how long it hold the buttons down, 1 blink is unlinked 2 is linked I believe. I also do not get welcome driver 1 or 2 when I enter the car, I have reprogrammed the fobs multiple times and tried to link it but it will not linked. Car starts with both keys and fobs function perfectly. Do you guys have any suggestions that might help me out?
