Does anyone know how to program an OEM key fob? I have a 2005 2500HD. I have an extra fob and my keys don't unlock my doors, they only work in the ignition. I'm nervous if my main fob dies that I won't be able to get in my baby. Thanks in advance.

new keys have to be programmed at the dealer

the parts department will cut it, service will program it

if it's just a FOB, no cutting just programming

 

do you mean the battery on the remote died?

cuz if so, pry it open and put a new one in

I dont know how it is in the 05's, but in my 08 all you have to do is select "relearn remotes" in the DIC, then hold both buttong onthe remote until the horn beeps, then continue with the next remote.... up to 8 according to the manual. maybe yours also has a similar option.

Close all the vehicle doors.

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

sparkstech beat me to it! Yep, those are the directions for 2005 (and 2004 and other years in that era). But a couple of tips:

 

- Obviously, since the doors are closed and you're turning the ignition key on/off, you do it while sitting inside. When you're all done, test the fobs locking/unlocking while you're STILL in the truck (don't get out and test from the outside). Also, roll down the windows, just in case.

 

- Once programming begins you MUST reprogram all of the fobs. If you blow it, the old fob won't work any more. So don't leave until you get it right, just start over.

 

- Have the fobs within easy reach and in the order you want them to be (#1, #2, etc.). Once you start programming them, there is a limited amount of time from when you finish one and have to start the next one (i.e., holding down both the lock and unlock buttons on one fob, and then the next fob).

 

- If it's like my '04, when I programmed 4 fobs (I'm not comfortable with just 2) the first one programmed becomes Driver 1, the 2nd is Driver 2, the 3rd is Driver 3, and the 4th is Driver 2 (yes, Driver 2 again). I bought 2 #1 fobs, and 2 #2 fobs. #1 is Driver 1, #2 is Driver 2, I overwrote the 2nd fob #1, on the back, with a 3 and it's Driver 3, and the 2nd #2 is also Driver 2).

 

Good luck!

Thanks guys it worked perfectly and easily, once I figured out that you were talking about the door lock/unlock rocker in the door. Thanks again. This forum is awesome for finding answers and talking to fellow Chevy owners. This is what it's all about!! :D

Is keyless entry standard on all the LS and above models? The '03 (LS trim) I'm looking the current owner doesn't have the key fobs. It has power everything. Can I buy a key fob and program it to work?

I really don't know for sure. Hopefully someone will answer this for you. I will check to see what the RPO code is for keyless entry and get back to you.

The RPO code on my 2005 is AUO. I would assume that it is the same code for the 03 you're looking at. They are located on the inside of the glove compartment and are 3 digit alphanumeric.

Depending on the exact remote option it may be a different rpo. You can post your vin here and someone is usually happy to post a build sheet or you can copy your rpo label and search them here which you can find in the upper left under navigation rpo looku[.

Is this a common problem on a lot of trucks? My truck is the same way, the key only works in the ignition, NOT in the doors.

 

Also, is the programming sequence the same for all years of trucks? I have an '01 Sierra, if it makes a difference? Also, what is the going rate on the key fobs / best place to buy them???

 

Thanks

Ok looks like the truck I'm looking at does have keyless entry. Where is the best place to buy key fobs? It is a '03 so will the instructions above work for it?

      He has his dad’s newer truck he’s put away. He has several old cars he rotates between him and his family. I’ve seen a restored square body and a SS Chevy truck he’s sometimes drives. He did raffle off a new suburban recently. As much as he is watched if he drove new stuff as a rule we’d know it. It would be fine by me. I don’t care what people prefer. I got one more new one in me. I’d rather my wife get one. I can’t get her out of the Genesis. Don’t tell anyone. I want her to get an electric truck. I want to put a generator in the back. Just because. She hasn’t bit yet.

      Yes, you must have seen my thread on the Blazer. HOT GARBAGE, but I love them anyway. I'm convinced every car guy has a soft sport for an S/T series somewheres. Probably even a Panther too, if I'm being an honest car guy. That doesn't mean they aren't junk. And they definitely don't get better with age. I sometimes play with old cars, but that's by choice. I don't rely on them and they aren't my everyday fleet.   Derek plays the common man on Youtube and that's no doubt where he started. Now he has Youtube money (and Motortrend, etc). You think his crews and his wife ride around in old beaters when they're chasing him and his wrecks across the country? No he's got newer and nicer stuff for that, you'll see glimpses of it in the footage.

      You refuse to own anything made in this century yet you reportedly own... a 2007 Silverado, which is now almost 20 years old. The dissonance.... turn up your hearing aid?   You clearly don't understand the government contracting process, brother. We send people to die on front lines, keep the public safe, and make people's husbands, wives, children enter burning buildings with equipment from .....wait for it.....   ...the lowest bidder....   Just because something is used for a long time doesn't mean it's good. But it might be cheap and plentiful.   Please, continue to whine about new trucks in a thread dedicated to new trucks, which you've said you'll never own. We get it. Go tell everyone how you're stuck in time on a Panther forum. I mean, Jesus, an 86 isn't even one of the good Panthers.

      It really is comical when people don’t agree or see the reason some people prefer the older vehicles. They become condescending. All the while they may be busting their knuckles on old vehicles. I have found memories of swapping out engines in my old GM cars in a weekend without much hassle. Unlike today. One wrong move a computer will shut you down. Even on something as easy as a brake job. There’s a pretty comical YouTuber called the car wizard. A garage owner who puts it all in perspective. Another Vicegrip garage that’s shows just how tough the old stuff is.

      I was around and remember that era very well, so I'm calling b/s on that statement. If they were that bad no police department or taxi company would've bought a single one ... but they were used in both services (and fire) for DECADES. They were bulletproof and proven. Even the early 21st century ones weren't too bad! The early models were legendary.   Mine is proof, but people like atlas are blinded by agenda and refuse to believe facts right before their very eyes.   Even decades after they were built, a new generation started driving them, posting all their builds and shenanigans on Grandmarq.net and Crownvic.net. The failures would show up then, since they all were deep past 100k-150k miles by that point, and younger drivers tend to be a little aggressive, especially with vehicles than can lay a one-tire fire for as long as you hold your foot in it. They've more than proven themselves over the decades.   The only thing that'll really take them out is road salt. The bodies and sheet metal were garbage. A victim of the cheapout FoMoCo and GM have been partaking in before then, and since.   Today it's the stuff that counts - the undercarriage that rots away first!    GMs Caprice was no slouch either. Reliable as a stone ax - the opposite of what they build now.
