I want to lock my keys inside…

Locking fuel door?

Open fuel door. Lock truck. Toss keys in the fuel door and close. Unlock truck with app, then unlock the fuel door.

 

I agree with @sandiegosteve - I have a 2022 Tundra, albeit it's in the shop now. I surf also.

CANNNOT get the alarm to not activate when I use the valet key. I asked the dealer about this, and they said it's just how it is. Not sure I believe them, but I couldn't get it to keep the alarm from activating. Turning the key fob off-and-on isn't the issue. It's the alarm of the truck setting when the manual key is used to lock the doors.

Is there a "hack" someone knows about?

NOTE: For those who have tested it, if you unlock the door within around 30 seconds (could even be a minute but not longer than that), the alarm isn't activated yet so the horn won't sound. But if it's more, it's time for the honking. I usually warn whoever is around that my car is about to honk. My old 2016 Tundra didn't do that, which was a nice feature.
