Even if they look the same the ignition has more "cuts" than the door. The final cuts are guess work.
My solution. Visit a wrecker that cares more about crushing than parts. Cost for a used ignition with 2 keys, two door locks and a rear door lockset was 20 bucks. Mine came from a windstar mini van.
Next take a drill and drill the ignition. Tape the drill bit so it only goes 1 & 3/16 deep. This breaks the tabs and lets the ignition pop out without damaging the housing. Vacuum and blow out all the debris. It's all white metal and drills easy. Insert the new cylinder with the key in the slot. when it clicks remove the key. Your done with the ignition.
Next remove the door locks by slipping the u-shaped clips. Install the 2 new/used locksets. And finally remember you also got for 20 bucks a tailgate lockset. Now your tailgate, doors AND igniton are all on the same key, which they were not when you lost the darn key.

20 bucks and about 2 hours,,,,,, I'm happy!!!!
