Can any other than the dealer program a key? How much?

 

I already have a key that's cut and a working FOB. I just need the ignition key programmed.

You can do it yourself if you have an original key to the truck still. If you are replacing a lost key, different story.

 

Adding a new key to original keys already programmed (must have at least one original):

 

Take the current learned key, turn the key to the ON position.

 

Turn it of and remove it.

 

Take the new unlearned key and turn that to the ON position.

 

You will see a message with "(number of keys) programmed." You will leave the new key in the ON position for about 10 seconds to make sure it learns it.

 

Start the truck with the new key!

 

If you are replacing a lost key(s) and have no other spares already programmed:

 

With an unlearned master vehicle key, turn ON the ignition, with the engine OFF.

 

Observe the security indicator, after approximately 10 min the indicator will turn off.

 

Turn OFF the ignition and wait 5 seconds.

 

Repeat steps 1 - 3 two more times for a total of 3 cycles or 30 min.Start the vehicle. The vehicle has now learned the key transponder information.

Thanks much. It worked first time. I had asked the dealer for a 3rd set of keys when I bought the truck. They mailed a fully cut key to me with a new FOB. I had programmed GMT800 and 900 keys, but not a K2. I thought I had read where the K2 couldn't be programmed without dealer equipment, so it sat in the drawer for 3 years. Now, I've misplaced a set and need a second set. Thanks again.

BTW, the dealer I bought the truck from is 100 miles away and a local dealer wanted $133.

Just an FYI. This exact process will not work on a '17. There is a process but requires 2 "known" keys to learn new keys. GM has upped security for '17.

Correct. I found that out the hard way even after I read the updated procedure the month before LOL.

I realize this is an old thread but im in a bind. I just bought my truck and i only have 1 key and 1 key fob. What are my options to have 2 working keys in my truck? I read about the 30 minute procedure but if i understand correctly that will only program 1 key so again trying to add a second key wont work correct?

Ok guys I just dropped my truck off at the locksmith and he actually told me how to program the key myself. I have a 2019 Silverado 1500 legacy and he said that after the 30min procedure there is a 9min window to program the old key back in and more keys. You actually have to program the second key or the truck wont start. I went ahead and let him do it and a remote for $50

I just got this to work on a 2018 Sierra using this process - worked great and total cost under $20.   Key B119 from car and truck remotes and Ace cut for $10

 

 

Thanks to  car keys express for info:

Adding Gm Basic Transponder Keys Must Have 2 Working Key (Manual Procedure) Up to 2017 and Up

  • Insert a master/working key and switch the ignition on. (I waited for security light to go out)
  • Insert the SECOND master/working key and switch the ignition on.
  • Wait for the security/immobilizer light to go out. Switch ignition off and remove key.
  • Quickly insert a UN-programmed key and switch the ignition on.
  • Wait for the security/immobilizer light to go out. Switch ignition off and remove key.
  • The key is now programmed.

DIC also showed that I had 3 keys programmed.

Happy Camper now!!  Hope this helps someone.

Wow Ace cut it for $10 that's cheap. Do you know if they cut it by code or copied one you had using a tracer type setup? Also does it matter if the door is open or closed?

      Tonneau cover that does not leak water

      By cherryred21duramax · Posted

      Thank you.  I really appreciate the well wishes.  I'm an engineer in the telecom industry, I know hardly anything about marketing.  Over the years I did some videos for nonprofits and web sites for small businesses and the seed was planted.  Agree with over-buying, I started shooting on an iPhone before I got my first DSLR and tripod.   I'm looking at trucks with potentially 150,000+ miles to keep the cost of entry low while focusing on the client experience and equipment.  Good wireless mics for interviews, the right lenses & lighting to look professional.  But I don't want to be late or break down, the stress of emptying a trailer & securing a rental truck right before a gig would negate any savings from buying a junker.  So anything that leaks water, has extensive rust, or generally unreliable I'd like to avoid.   Does GM/Chevy overbuild these trucks for upfitting?  I talked to a local upfitter, they sometimes tie lights & other 12V into existing circuits, which I always thought was bad.  Which is why I enjoyed the AUX upfit switches on previous trucks (odd they mostly come with off-road or work truck packages).

      Looking at ordering a '26 WT because I want a std cab, std bed

      By Atlas · Posted

      GM's are stainless and have a fairly robust powder coating, although, still not worth $850 in my opinion. They will hold up a lot better than their cheaper steel aftermarket counterparts.   What I like about the GM step bars is dealers will often equip their dealer stock with them. Lots of margin. Which means a lot of people end up buying them because they're already on the truck, even if they don't like them. So it's pretty easy to find brand new takeoffs with hardware on Marketplace and Craigslist for about $250.   That's what I did for my crew cab. I wanted ZR2 rock rails for the look, but with the ability to bolt up GM's assist step package. From GM it's about a $2500 accessory all in. The old folks in my life can't get in the truck without steps. I found the whole package on marketplace for $180.

      Forward collision and lane keep assist still a problem on 2022 refresh?

      By kr477 · Posted

      I am really glad I found this post and this site... We have a 2022 1500 refresh LTZ that has these problems: - forward collision avoidance warning light - lane keep assist unavailable - adaptive cruise control unavailable   The truck was bought as a new leftover in 2023, so it was still under the 3/36 B to B when it went in for these problems earlier this year. It has been at the dealer on and off now for about 110 days now. These are some of the things they have done that I can read on the service tickets. - replace/add ground straps (4) - check all battery cables and vlts - replace serial data gateway module - replace front view camera - numerous reprogramming - a few calibrations (apparently ending with 'learned') Last week when I had it back the truck had those 3 warnings every time we used it except for 3 times. On three separate occasions the truck started and ran perfectly with no (zero) warning messages or warning lights lit - everything worked perfectly. Over that same time period the truck did not work on every other 'key' cycle which I would estimate at 60+ cycles. On those estimated 57 cycles it had the same 3 problems each and every time.   It is back at the dealer now - can anyone help at all with what the true problem might be?  Or possibly what can be ruled out leaving a lower number of possibilities? Thank you very much for any help you may be able to supply....

      As for the step bars, friend did just that, bought some cheap ones and we are in Michigan and they turned to rust in less than a year.  In 3 yrs he had to replace one of them because they rusted out from the inside even though he kept after them cleaning and polishing etc. Had to drive 300 miles (to Chicago area) to find a reg cab wt, he ordered one and dealer never got it and with winter approaching (plow truck) he needed fo find one ASAP.  Furd dealer found him one but he choose to drive to get a GMC.    Just what you can expect with cheap stuff, LOW quality.
