Can't Figure Out How To Program New Key Fob 2013 Tahoe LS

[t_bergman]

After 2010 GM removed the ability to add new keys and program the remotes via the dash controls. You might think that sucks but you did get redesigned door mech, double layer glass in the D/P side windows just like the windshield and a steering wheel lock.

There’s a product call AutoSync worth it’s weight in gold that’ll allow you to do the programming from in the truck. All the other features are bomb digidy.

2007-2014 AutoSync-G2 (GMT-900)

IMPORTANT NOTE EFFECTIVE JANUARY 15th 2023. All AutoSync's now include the torque converter lockup controller feature as standard equipment, however it will only be active/function on 6.6 Duramax diesel vehicles. The new second-generation AutoSync-G2 is now available...new features and...

I'm guessing that AutoSync needs to stay in the OBDII port?

2013 Tahoe LTZ Key FOB Info:
I recently watched a YouTube video where you can program a newly purchased FOB using the buttons on the dash. Step thru your dash buttons to see if the dash LED readout provides the programing function. Apparently, some older Tahoe's allow you to program the FOB this way, others do not. My 2013 did not.
I ordered a new FOD from Amazon (Brand name: Dorman 99156 Keyless Entry Remote 6 Button). Comes with the programming device that plugs into the OB2 outlet under the dash. Cost $63. Looks simple. It will be delivered tomorrow. I'll let you know.

UPDATE:
I received the Dorman 99156 Keyless Entry Remote 6 Button (FOB replacement kit) I ordered from Amazon. It included a new FOB and the FOB programming device that plugs into the OB2 outlet. It was very easy to program the FOB and the FOB works perfectly.
One Note-I bought this so that I would have an extra FOB, so if you have existing FOB(s), you must re-program all of them them at the same time and using the same method as you programmed the new FOB.

Wonder where the OP went - not a peep after folks chimed in with details.

Can the Dorman dongle be used more than once after it’s done its programming?

Can the Dorman dongle be used more than once after it’s done its programming?

I think I've read that it only allows 3 uses and stops working

That’s cool. I was expecting just one. Can’t wait for someone to hack it to unlimited and continually resell it to the next guy.
