Leaving Your Vehicle - GMC 2000 Sonoma Owner's Manual

Power Door Locks (If Equipped)
If your vehicle has power door locks, the switch is
located on the armrest. Remove the ignition key and
press LOCK to lock all the doors at once.
To unlock the doors, press the raised area next to the
key symbol.
Lockout Prevention
To protect you from locking your key in the vehicle, this
feature stops the power door locks from locking when
the keys are in the ignition and a door is open.
If the power lock switch is pressed when a door is open
and the key is in the ignition, all the doors will lock, and
the driver's door will unlock.

Leaving Your Vehicle

If you are leaving the vehicle, take your keys, open your
door and set the locks from inside. Then get out and
close the door.
Keyless Entry System (If Equipped)
If your vehicle has this feature, you can lock and unlock
your doors from about 3 feet (1 m) up to 30 feet (9 m)
away using the remote keyless entry transmitter supplied
with your vehicle.
Your keyless entry system operates on a radio frequency
subject to Federal Communications Commission (FCC)
Rules and with Industry Canada.
