Yes. I bought two nice remotes on e-bay in like-new condition, opened them up (by pre-heating them in lab oven to 180 deg. F for 10 min.) with razor blade. Removed key blade and small black transponder chip (not part of circuit board but loose by its self next to key spring mechanism) from my original and moved them both to donor remote then glued back both halfs with black loctite super glue. Pre-programmed chip is for starting your vehicle purpose and circuit board is there for opening your doors function. After inserting key into ignition, your vehicle's ignition collar receiver will recognize the original transponder chip, LED on dash will blink and All Activity Module will let you resynchronize the remote.
My manual is wrong. I found it now and here are my notes:
1. Close all doors.
2. Turn key to pos. 2 then to pos. 0 and remove.
3. Within 10 sec. press and hold lock button now press unlock 5 times.
4. Release the lock button.
5. PRESS TAIL GATE BUTTON TO END AND FINALIZE RESYNCHRONIZATION!
This last step is the most important that some guys missed in their procedure and it's not mentioned in owner's manual!
2001 may be diferent then my 1999 but I would try it out.
Good luck, Bernard
