The doors were designed not to lock by pushing the knob down and shutting them, keeps you from locking the keys in the truck.

You should be able to lock them by either, with the key or pushing down the knob inside.

Sounds like you have some internal issues that need to be checked. Also check your door alignment as the catch and latch may need adjusted to get the door to lock. Try pushing up on the door and using the key.
