A couple of weeks ago my key fob started acting weird. what i mean by weird is it wont unlock when i press the unlock button... i thought is was the battery so i changed it. nope, not the problem. i would try my other key fob that i got when i bought my truck but well how do i put this.... it was ran over by a fire truck.... i work for a volunteer FD and it fell out of my pocket in the station and the truck ran it over and i didn't notice it till we got back... any tips or ideas what it could be???

 

I have a 2003 sierra 1500... if that helps...

try to "pair" it back with the truck and see what happens...the RDLC should be on the passenger side of the GMT800 so approach it from the driver's side to really test it. Then try it from the passenger side to verify.

 

 

Edit: and quit running over the fobs with firetrucks...

how do you reprogram it... the cycle my buddy told me was

Insert the ignition key into the ignition lock cylinder.

Press and hold the door unlock switch.

While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF.

Release the door unlock switch. The doors will lock and unlock to confirm the program mode.

Press and hold the LOCK button and the UNLOCK button simultaneously on one transmitter. After a delay of approximately 15 seconds, the doors will lock and unlock to confirm the programming of that transmitter.

Repeat the previous step to program up to 4 transmitters.

Turn the ignition switch

to the RUN position in order to exit the keyless entry transmitter programming mode.

Operate the transmitter functions in order to verify correct system operation.

 

 

 

this right???

Check the points on the battery straps where it is soldiered to the board.... This is a BAD problem with nearly every make/model remote with a coin style battery. The metal strap should be soldiered in 3 spots on most GM remotes.

 

If your not good with a soldiering iron take it to computer repair place. Most of them will have a soldiering bench and they have someone very skilled in this........ I shake to bad to do this anymore......

However,

 

Edit: -- Ford Remotes and some other make (I don't remember which one thou).... Sometimes require a refresh of the remote if you change the battery. Ford's procedure is hold both lock and unlock for 15 seconds. Locks will cycle to verify the refresh has been completed. If it was not so FREEKN cold here I would go out and see if the other make is GM.....

I've seen this happen a lot also. I think the board flexes when the buttons are pushed. The soldier can't flex and it cracks. After repairing the soldier spots, I put a little JB weld on the outside of the battery strap.
