Auto door lock after engine off and leave the truck? Not available?

It only took about 1 year to realize that after I turn off the engine and leave the truck, the door are still unlocked. I am used to have the doors auto-lock for safety and privacy.
Is there an option for that? Nothing in the manual and no option on the vehicle customization.
I did not lock the doors from the button or remote fab and when returned to truck without the fab the door were unlocked .
I must have done this forever and not realize Is there an option for our tacos for that?

 

We don’t have that feature. If you turn off the truck and don’t press the lock, it will not lock by itself.

 

Hmmm my 18 tundra auto locks after 60seconds

 

I just touch the handle after I shut the door, like mentioned above.

 

if you unlock the truck and do not open the door within a certain time frame it will auto lock. but not after shutting the truck off...you must lock it manually when you turn the truck off and leave it

 

Keep it off mine- nothing worse than driving out to a very remote place for over a couple hours, getting your stuff out, changing into warmer clothes and putting on your pack, and turning around and hearing your doors lock while your keys are still in the pockets of the shorts you just changed and left in the truck.

 

maybe a resident electronics guy can figure a nice mod out......

 

it only relocks if you unlock the doors and dont open any. think its set to 30 secods from factory but you can change it to longer or shorter or completely disabled.

 

Nope, these trucks do not have passive locking, my vette has it but I have it turned off.
