There is a “no fob” reprogram process outlined in the manual & it wipes out all the currently programmed fobs. That is the process you’ll need to complete. Of course you’ll still need to rekey all the lock cylinders. That’ll be the more expensive part of the two.

I had the exact same issue. Same messages on the screen, had WiFi but no internet connection, apps that require data didn’t work, etc. I was on/off with Onstar a few days. They had finally escalated my issue to a higher level of tech support. It was getting late in the evening & I told them I was done hanging on the line with them. They said they were going to continue to look into it & they would call me the next day to further troubleshoot the problem. By midday the following day, my problem was gone & they never called me back. Haven’t had an issue since.

It’s handy as hell. I don’t always have my fob on me when I need to access something out of my truck.

My 2014 Sierra Denali 1500 had a second battery tray. I had the compressor located there for my Air Lift air bags. Not sure if the newer 1500 models have a second battery tray though. Perhaps it depends on the options or trim level.

You’re fine. The sensors themselves are inside the tire. If they get wet, you’ve got bigger problems.

It is backlit. I don’t think that the battery is meant to be replaceable. The whole unit has to be replaced once the battery dies. Although where there’s a will, there’s a way. I’m sure it could be done.

I purchased two chipped keys for my 2020 GMC HD as a hidden spare key. It was $15 for both from Amazon. I had them cut at a local dealership for $12. Mine is push button start so the mechanical key allows me to open the door & then I place the key in the transponder pocket & I’m able to start it. I realize your truck doesn’t have PB start but I think a similar set up would work for you. I did the same thing for my 2014. I also bought a spare FOB & had the integrated key cut at the same dealership. The FOB I learned to the truck myself.

I get that error all the time. Sometimes shortly afterwards, I’ll get a message saying that the brake controller has been recalled. Even if I don’t get that second message, when I confirm the controller setting, the preset output is always at the correct setting anyway. I just associate it as one of the numerous glitches that this system had.

I use Bullring tie downs. They retract when not in use. https://www.bullringusa.com/product-category/tie-downs/?gclid=EAIaIQobChMIrdL2-82H6gIV6cuGCh1tjAW0EAAYASAAEgLcPvD_BwE

Have you done a search on the forum? There’s a bunch of topics discussing the trailer camera.

Yes, the dealer needs to perform the program.

I ordered the straight 2020 style for my 2020 HD but received the earlier slanted style. Doesn’t look as good but it works well. It’s a nice backup to access your truck. I keep a chipped key programmed to my truck inside. In the event your keys/phone are misplaced or stolen, you’re not stranded.

SOLD!

I bought mine from 1A Auto. I know there’s other vendors also. https://www.1aauto.com/search?q=Tow%20mirrors&year=2014&model=1719

I did the 2x6 thing and sprayed it with bed liner in a can. I also made moveable pieces to use as dividers.
