I have a 2008 cr-v that recently had its ignition replaced, with a used ignition that came with a key that runs that ignition. My old spare key is installed reading codes?!!! And the other original key opens the doors but cannot start the car. The new ognition key starts the car but cannot open the doors. I tried the diy programming with the ignition key , 4 times 2nd position, doesnt work, just hoping it could open the doors and the start the car. Cheap suggestions on how to get two fully operation keys?
