I cant seem a way to figure out how to lock my keys in my AT4 without my doors auto unlocking.  I

 

do this in my other SUV and use the app to unlock so I cant lose my key.  I do this when I go places like amusement \ water parks so there is no chance I can lose my key and be stuck 100+ miles away.

 

Anyone know what setting im missing to accomplish this? 

 

Thanks

I believe an electrostatic bag might work. You should be able to put you keys in it and lock the truck. 

Anyone else have any knowledge on this?

I'm not sure on the new ones since the keys are setup as a keyless fob but on the older trucks you could go into the radio and turn off the safety lock that unlocks the door if you have the door open and hit the lock button. I think it's auto unlock or something like that in the radio.

I'm not sure how but it can be done. I will take a look at my settings. I lock the key fob in my truck all of the time. Also a point of interest, GMC has an accessory keypad (a knockoff of Ford's) that I had mounted on my door. ($250 installed at the dealer) that works great so far. You can lock or unlock the truck and therefore the tailgate without the key fob. I lock my keys in the truck all of the time and dont even need a phone to unlock.

I can lock my keys in my AT4 with my phone, sometimes the button on the door works. There is a setting to turn off the 3 horn honks that tells you you locked your keys in the car, I turned that off maybe that has an effect.

2021 GMC Sierra 2500

I need to be able to lock both key fobs inside the truck. I had a touch pad installed so I could reenter. 

 

The electronics will not allow me to lock the fobs inside. I surmise there must be a way to disarm the auto-unlock.

 

How can I do this?

It's on the settings section of your radio

Solution: 

I had a GM touchpad lock installed at a cost of $145 plus less than 1 hour labor. Still GM support and the service manager did not know what it would do. 

1. I purchased 2 "Faraday" pouches (9.95) for my fobs and hide them anywhere in the truck or the bed. The truck now does not sense their presence. 

2. I can open the doors with my custom combinastion. I can lock the doors with the touchpad command.

3. The big difference is that if someone enters the truck they cannot start it because the sensor does not know if the fobs are on board or not and the potential thief doesn't know either. 

4. If I have left fobs in the truck I can return from fishing or hiking and get in with combination. 

 

No one at two dealers nor at GM support knew any of this. If there is a disable command in the radio I could not find it or it would not address an on-board fob.

So, did you manage to accomplish this? I would also like to have this, but I don't know what I need for that. I thought I might need an electrostatic bag. Well, that didn't work. I tried to change some settings in it, still didn't work. I went to the dealer, they told me I should get a newer key that costs almost 1k!

You need the touch number pad for the exterior of the driver's door.  It's available via GM Accessories, and requires the dealership to do a computer programming for the touch pad.

The easiest non tec way would be to wear it around your neck via a neck chain. I use to keep a spare key on my tailgate post tied to a wire. On one truck I could slide it behind the gas cap lid bracket. So these high tech trucks still have keys? If not then sentence one.

Go camping outside of cell range and accidentally close the door with the keys inside while packing up.  Regardless of the owner's manual saying it won't, it's sure-fire way for the vehicle to lock itself for some reason.  Ask me how I know.

I've had that happen too.

yeah i had that happen too, that's why i always leave a window down just enough to get my arm in to open the door.. a smart guy would go to a locksmith and get him to cnc a nonprogrammable key to hide somewhere.

      Roll up bed cover experiences

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.

      Thanks to the convenience of Amazon, I was able to get a few things done to the truck today.  I installed Carquest Premium oil and air filters with five quarts of Mobil1 High Mileage 10-30 along with a quart of Pennzoil Platinum 5w-30 I already had.  The latch for the flip up center console lid was broken so I replaced it along with the power mirror switch.  I found my push retainer assortment this morning and reattached the plastic under the bumper and it was only held on with a few screws and retainers.  Then I programmed a new remote keyless entry fob so I can lock my dog in the truck when I take her out with me (I've got to keep the air going for her since it's been in the 100s).  Finally, I ordered some LED interior bulbs and replaced the reading lamps.  The front lights are working fine while one of the back lights only works intermittently and the other not at all.   While under the truck, I found the source of at least one of the noises: the sway bar links need replacing.  I ordered a set of Suspension Dudes links with Code Red bushings.  Never heard of them, but they're made in the USA and have decent reviews.  While making yet another Amazon order, I went ahead and added a set of front tow hooks.  I went with red, since that's the color of the sway bar link and bushings and it should look decent enough on a black and chrome truck.  Speaking of which, it doesn't bug me much, but the passenger side mirror has a chrome cap while the driver side doesn't, so eventually I'll make them match one way or another.  Oh, and I ordered a $20 TPMS reset tool.  No idea if it will do anything for my sensors but it was cheap and will work for the Ford Transit Connect as well.     For tradition's sake, I ordered a new oil change wrench.  I kept the Snap-On 9/16"x15mm GM wrench I bought when I was 18 in the 2006 GMC from the time I bought that truck until the truck was lost.  While I was tempted, there's no need to spend $80 for a new SO wrench, or even $50 with shipping for a used one on Ebay.  I just bought a Duratech 15mm extra-long ratcheting wrench to do the job as needed.  It works, and if I like that wrench enough, I'll buy the set.

      Multigate electrical problem

      By Another JR · Posted

      The recall is for exactly this issue - those drain holes combined with the limited environmental capability of the tailgate electronics card inside the tailgate were a problem. The “safety issue” was the potential for the tailgate to spontaneously open, but all kinds of tailgate misbehavior can occur from water contamination of that control card.    There is no real fix yet. The initial recall just disabled the tailgate. Later, when parts became available, they would replace bad parts with new parts of the same bad design. My dealer is going nuts because the few times I let them get their hands on my truck, my tailgate is off due to a slide-in camper installation. They really want to cut my tailgate wires, but I won’t give them the chance. I will let them get their dirty hands on it when a real fix (redesign) is available.  My tailgate, which works just fine with sealant plugging the drain holes, will remain safe in a dry storage crate until then.

      Yes your absolutely right, I been looking at the 4 inch BDS one and it acutely states you can use the stock 20’s just not the 17’s or 18’s, I also didn’t realize that with my 275/60r20 stock wheels I’m already running 33 inch diameter wheel setup lol so I can just run my stock wheels and tires atleast to start.

      I would expect that to be lift-kit dependent.  If the kit has interference issues w stock wheels, then the kit/manufacturer should indicate that somewhere.
