I just replaced the PCM in my 2006 Ranger. The new PCM came with 2 keys, that I was to have cut to match the original key, which I did. The PCM came with instructions how program the new keys on first start up. I followed the instructions to a tee.my truck did not start. Went through the instructions again still no start. So tried the old key, and it started. How is this possible? Is there something wrong with my truck for this to happen??
