Here's the scenario....someone has a set of keys and key fob for my truck that I cannot get back and I want to prevent them from tampering with my truck. 02' 3500 LS DRW I wanted to see if anyone had a suggestion on changing out the door locks and ignition switch. I would also like to know if there is a way to re-program my key fob to a new one so theirs will not work. What would you do...and getting the key/fob back isn't an option. I am pretty mechanically inclined and I do have a subscription to ALLDATADIY for reference. Thanks for any help on this.
