what is a keypad? I need to do the same thing with my 2023 yukon. thanks
Once you purchase keypad, you have to take to dealership, give them the card and they have to request a file from GM. Once the vin specific file is built, gm sends to dealer. Took 8 days for GM to send file to my little dealership. Once they got the file, they loaded it up, downloaded it into my suburban, and we stuck the keypad on the window door frame. Programming/downloading to the subruban took less than 5 min. Works great. I put my own code in, took about 2 min following instructions.
No instructions on use were given.
This is what I have learned playing with it
Touching 7/8 & 9/0 (bottom two buttons) locks doors when you get out shut door, engine running. Will run as long as it has fuel I guess. I have left my for several hours and didn't turn off. You don't have to take key fob out of pocket. To unlock you can enter code or just touch the handle button to unlock.
Entering your code unlocks.
Entering your code and pressing 7/8 button 4 times opens rear door. Press 7/8 4 times will close door.
Entering code and pressing 5/6 button 4 times opens the rear glass hatch.
So far that's all I can remember.
I use it daily, getting out and locking doors to go in places. Leave dogs in there with A/C blasting, and wifi is still running, so I can view my web cam to check on things, while out and about
