yellowblue Door Locks CAUTION: Unlocked doors can be dangerous. Passengers -- especially children -- can easily open the doors and fall out. When a door is locked, the inside handle won't open it. Outsiders can easily enter through an unlocked door when you slow down or stop your vehicle. This may not be so obvious: You increase the chance of being thrown out of the vehicle in a crash if the doors aren't locked. Wear safety belts properly, lock your doors, and you will be far better off whenever you drive your vehicle. There are several ways to lock and unlock your vehicle. From the outside, use your key or the remote keyless entry transmitter (if your vehicle has this option). To unlock either front door from the outside with the key, insert the key and turn it toward the front of the vehicle. You can lock either front door from the outside with your key by inserting and turning it toward the rear of the vehicle. To lock either front door from the inside, push the locking lever forward. To unlock either front door from the inside, pull back on the locking lever. 2-4
