Locked inside

[Smallblock454]

Hm,

i would check the control unit alarm system below the drivers seat and the door lock modules. Can be a microswitch or bad wire connection. Can also be corrosion in the control unit alarm system - water damage.

If the car relocks, i would question if the alarm system is still active while you're driving. So do you open and close the car with the key fob and does the key fob work properly?

I had a problem once where doors would lock and unlock on their own after starting the car. It turned out the electronic door lock mechanism on the passenger side needed replacing. Once done, I've never saw this odd behavior again.
