S600 ReNNtech ECU upgrade
Hello everybody, I'm new here and I have a simple question that you guys probably know.
I recently bought a 2003 S600 (will put pictures soon) and am considering the ReNNtech ECU upgrade and am wondering if it resets the key fob. Do you have to reprogram the key to the car or does it work right away. Thanks in advance.
