03 Express Remote Key Fob Programming Procedure?
 

I picked up two new fobs and am having an issue finding any DIY procedure for this year Express/ Savana.

The procedure for most truck of this vintage (Hold unlock, key on/ off cycled twice) does not work. The other method I found was jumping the 4 & 8 pins at the OBD2 port but have not tried yet because I'd like some confirmation before I short any pins :). Owners manual states that programming can only done by the dealer of course.

Anyone that's managed to DIY this so far? Thank you.

Hi, maybe try a reputable, insured and bonded locksmith.

At a certain year, I cannot remember which, that procedure no longer works. You have to go to the dealer for a relearn.

2003 - 2007 Express: It requires electronics that the dealer plugs into your vehicle.

It's confusing, as other '03 models accept the older method.

Thats too bad, locksmith/ stealership it is. Thank you gentlemen!

Quick update in case anyone has to deal with this issue. Called around to 4 local Chevy dealers, was quoted $75 by 3 and $50 by one. I made an appointment and the lady tells me its $148 and an hour of labor (LOL). She said "Since you don't have a working remote with you, we have to go into the system and delete any existing fobs and reprogram everything. I called her BS saying it takes less than two minutes to plug the tech 2 in and program, she made a call and dropped it down to $74. I cancelled and figured I'd rather take my business somewhere local that isn't trying to play games with me.

I found a local locksmith who did it for $55, sure enough it took a minute flat to program both fobs. Screw the stealerships.

Bravo. I'd do without before I allow anybody to gouge me like that. I don't know where you're at, but trash them on Yelp.
