Hi, I recently lost all my keys to my 98 es300 including master key. So I bought a set of transponder keys from ebay and had the dealer cut them and also took just the ecu, and not car to have reflashed. The instructions that came with the key on how to program the key including the instructions I searched for on here require you to have an excisting programed key. My question is if there is another set of instructions on how to program a master key to a reflashed ecu without having to use a programed key? Thanks for any help guys!
