How to program doors to automatically lock at certain time?

We have had a rash of break-ins and thefts from our neighborhood vehicles, and of course — it did not matter until I became a victim. Apparently, thieves come along late at night, check your door handles, and if they are unlocked — help themselves to your property.

I know, LOCK YOUR DOORS. Deterrent #1. Also, I know I can have flood lights, surveillance, car alarms, and all of that. However, there is also the human element that may forget to lock those doors and activate the alarm one night with an armful of groceries, and kids in tow.

That said — the lazy engineering side of me believes there MUST be some security system or custom method to program your car/truck doors to LOCK at a specific time each night (if your keys are not inside). Does this exist?

With home automation, I can have lights turn on or off when I come home or drive away, I have a robotic vaccum that cleans my floors every night, and I have Amazon/Google Home which do tons of automated things for me — not to mention, we have auto locks when cars reach a certain speed. Makes sense that the automotive industry has this time-based automation possibility as well.

Any leads would be great!
