1. Check the Owner's Manual: Your owner's manual is the definitive guide. Look for sections on door locks, security, or power locks. There might be a description of how to change this feature, though it's not guaranteed.
2. The Ignition Switch Method (Most Likely): Many vehicles from this era automatically lock the doors when the vehicle reaches a certain speed (usually around 5-10 mph). This is often *not* controllable. The only way to prevent this would be to manually unlock the doors after you start driving.
3. No Adjustment Option: It's quite possible your 2002 Chevy Venture doesn't offer an option to disable this automatic locking feature. GM vehicles of that era weren't known for extensive in-car customization of this function.
4. Dealer or Mechanic: If you're determined to disable the automatic locking, a Chevy dealer or experienced mechanic might be able to help. They could check for hidden settings or even potentially modify the system (though this might be expensive and may void any warranty). They would be your best bet to determine if it's possible.
In short, expect it to be a feature you can't turn off directly. Your best option is manually unlocking the doors once the vehicle is moving if automatic locking is a problem for you.
