2000 Chevrolet Suburban Owner's Manual - Page 79

Your vehicle has one double-sided key for the ignition and all door locks. 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. Use the keyless entry system (if equipped) or use the door key. You can also use your key. Your vehicle may also have a key that locks and unlocks the center floor console only (if equipped). If you ever lose your keys, your dealer will be able to assist you with obtaining replacements. 2-3
