Try this first. It worked on mine.
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 keyless remote. 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 four transmitters.
Turn the ignition switch to the RUN (one more click forward) position in order to exit the keyless entry transmitter mode.
Operate the transmitter functions in order to verify correct system operation
There you go!
UPDATE #1: After messing around with a couple of Key Fobs, I noticed that most owner’s manuals have the programming directions already. Check your owner’s manual first!
I will try to post a how to on programming keys.
UPDATE #2: I have tried this on a 2001 Grand Prix GTP and 1999-2002 Grand Am GT
UPDATE #3: This only works for some GM vehicles from 1996-2005.
what car did you try this on?
2001 Pontiac Grand Prix GTP
Tried it on a 99 silverado……….Worked great! Thanks!
Just reprogrammed an old fob from the wife’s Pontiac that she wasn’t using, for my 03 Chevy Avalanche. One thing to remember is when you program one you must do all at once, as the old one looses it’s program when you do the new one. Works great. Thanks, JoeW.
that was quick and simple, thanks andrew
After half a day coordinating to drop my 2008 Trailblazer off at a dealer, arrange a ride to work (allowing them all day to do what they say takes an hour) your instructions came up first on the search engine…ten minutes later, my new key fobs work!!!! So if you’re keeping track, this procedure worked on my late ’08 Trailblazer…first attempt! Thank you!
PS the directions weren’t in the manual for this ’08TB, but I do remember reading them in the manual for my ’02 TB.
WORK GRATE ON MY 03 TOHOE THANKS !!!
bought an 08 impala (auction repo) no key fobs dealer wanted 119.00 (ea) for new one’s ( because of factory remote start ) and 45.00 to program. bought fob on ebay 15.00 ( no not joking ) use info found here. workes great …. 15 dollars for fob… 0 dollars for programming….screwing the dealer out of 149.00 dollar profit PRICELESS
And now we all know why GM Went Bankrupt…
tsk tsk tsk!
Its to bad that it don’t work on a 2008 G6
This worked on a 99 olds. You don’t get the queues (doors locking/unlocking) till you’re done. Then it honks once for you to let you know it worked.
Programing the GM Key Fobs worked, I had asked the Chevy dealer how much to reprogram my key fob, they told me $50.00, because I had to have the chip rescanned, They must think everyone is stupid, there is nothing in the fob to hook up to to rescan. So I found your instructions and It worked fine on our 2001 Chevy Blazer. Thanks guys. I really don’t like being lied to….
once its programed will it also work the trunk on models where thats an option?
yes
I tried this on a 2002 Grand Am and was not able to enter the programming mode. When you say to cycle the key On/Off/On/Off is that all the way to ignition, Accessory, etc?? Not sure what I am doing wrong
Unfortunately the 2001-2002 Grand Ams need a dealer to program the fobs. Sorry 🙁
went to the dealer today with 2 fobs from an impala I have an 06 grand prix they told me after they charged me 60.00 that the fobs are incompatable and that i need new transmitters for the old ones at over 200.00 each are they trying to sell me something I don’t need any help or suggestions would be appriciated
I would get on ebay and purchase the fobs from there. They are usually $20-$30 per fob. You can actually program new fobs in your Grand Prix info center. Those fobs should work IF they are from 04-08? Impala. Good Luck!
What about 2002 Bonnevilles?
I just purchased a fob for my 2005 pontiac g6 Gt on ebay for 19 bucks (dealer wanted $130 plus $54 programming)…
will these instructions work for my car?
thanks
Check the owners manual. I think you can add it without any special programming. I think it is located in the “driver information center”. Good Luck!!!
Sorry; Dealer only.
Will this work on a 2008 Grand Prix? I am trying to help my girl get the new fobs to work….thank you.
Check the owners manual. I think you can add it without any special programming. I think it is located in the “driver information centerâ€. Good Luck!!!
All done in less than 3 minutes on 2003 Suburban LT
for 2 fobs. “Time is closer to 20 seconds for response to each programming authentication/confirmation locking. When you exit programming by turning on key switch the horn beeped once”
Thanks Andrew
2000 blazer with no success and i dont have a manual so ill have to get one
how about a 2003 Chevy venture. Nothing in the owner’s manual
how about an 01 Olds Aurora????
Couldn’t get it to work on a ’98 k1500 silverado. Any ideas?
Hey,
I will this work for an 08 Sierra with auto start?
Thanks
Don
BOUGHT NEW PHOB FOR 2005 CHEVY MALIBU MAXX FROM DEALER,95.00.HE SAID HE WOULD HAVE TO GO OUT AND PROGRAM IT .WHEN HE CAME BACK IN SAID EVERYTHING WORKS BUT THE AUTOMATIC START .DO YOU HAVE THE ANSWERS FOR ME .
will the start function work after doing this
FYI guys, when they say that a given car & fob must be “programmed by the dealer”, I believe what they are really saying is, “on this model, instead of the on/off/on/off trick, we designed it so that you must jump 2 pins on the ALDL/DLC, and we don’t want average morons messing with that.”
On my ’97 Riviera, you simply make a small jumper wire (even a paperclip would probably do) and jump Pin 8 to Pin 4 on the Data Line Connector under the left side of the dash, where scan-tools are hooked up… Then you turn the key on, hold down your buttons on each transmitter, and remove the jumper.
I can’t guarantee it, so no warranty is implied or granted, but given the limitations on the pin assignments by the OBD-II standards, I would think that all the GM’s that need the jumper wire trick would use the same two pin numbers…
Do the #’s on the back of the FOB’s have to match? I purchased them from Ebay but the instructions above are not working for my 05 Chevy Uplander. Has anyone else tried to program an 05 Uplander?
Many thanks!
Ron
it works great on my 03 Sierra less than 30 seconds thanks
I bought GM fob from ebay for 07 Chevy Cobalt do I have to have mine programmed at the dealer??
The car might not have auto start enabled. I would check your owners manual.
Correct
On the 03 Venture, you will have to go to the dealer.
Check the “Vehicle Center” while the truck is in park. There should be an option for it.
You can do it yourself.
Depends on your vehicle.
Has to be programmed by the dealer.
Dealer only.
Easy fix:
1. Locate the Data Link Port. It is located under dash drivers side. Be sure you know which pins are 8 and 4.
2. Make sure there are metal contact pins in terminals 8 and 4. Connect 8 to 4 with a suitable
jumper wire (leave the jumper wire connected throughout the programming procedure). Make
sure you know which terminals are 8 and 4. The vehicle will respond by locking and unlocking the
doors to signify entering of programming mode.
3. Press and hold both the LOCK and UNLOCK buttons together on the first transmitter to be
programmed. After about 15 seconds, the vehicle will respond by locking and unlocking the doors.
Release the buttons on the transmitter.
4. Within one minute, repeat the previous step on the remaining transmitters to be programmed.
5. Remove jumper wire applied to the OBDII Port.
Will a newer gm truck fob ’07-’10 program to an older model ’03-’06? Has anyone tried doing this with other models?
no
It worked on my 03 Silverado, but there was one additional step that I discovered accidentally. After cycling on-off-on-off, the doors locked and unlocked but the fob wouldn’t program until I put the key back into the on position. Hope this helps, thanks for the great tip!
You need to remember it isn’t GM that is charging you $150. to reprogram it is the private Business you elected to go to.
Find a dealer you can trust not to rip you off or dont complain.

Steve – did you ever find out how to do this with that vehicle?
Thanks,
