Just go wrench on your own car, like OP. You'll be amazed at all the funky ways you can gain access without a key. Not really secure, but difficult enough to prevent the casual shenanigans. This stuff predates the automotive IoT crisis too.
Makes you reflect on how, most of the time we rely on a baseline trust placed in most of the people around us.
Literally all of civilization is built on the back of that, and if it erodes then We're doomed.

If you mess with your front door lock, make sure to do it with the door open, to prevent locking yourself inside when the pins get jammed into the keyway as you turn the lock 180° (don't ask me how I know this).
or sometimes, even just shim it open.
That's because in nice places, locks are vestigial. There are no criminals around, so they'll never be tested. And few criminals try to pick locks. They just smash a window or kick a back door open.
No wonder the ratbag kids these days are running around with them - they're only like $400 on Aliexpress and Temu. The world of "all keys lost" shenanigans is a wild one.
