I have a 1999 TL with one key and fob, both working properly. I want to get two more of each. Once I buy keys and fobs and cut the keys, what are the procedures for registering? Thanks!

 

Have a locksmith cut you a key, then have him program the key to your car. He can do that by using the key you have, he’ll essentially just copy one to the other. Search on YouTube on how to program the keyless fob the procedure is very simple.
