Hey gang, I recently purchased an 03 EB Expy that was a "salvage" vehicle. It only came with the fob and one key, but the keyed door lock is broken. After a trip to my closest pull-a-part, I found a door handle with lock cylinder, ignition lock cylinder, PATS halo, and 2 keys! I was wondering if anyone knew of a way to utilize these as a "one key sytem". For instance could I just swap out the halo and the other keys would work, or are the RFIDs stored to the pcm? Could I trick the truck into thinking the original key is being used, but use the other keys? Specifically I'm thinking take the halo out of the column, put the old key in it under the dash, then swap the cylinders to work with the other keys. Any insight you might have would be great! I just don't want to be stuck if I lose my keys!
