Doing so would ACTIVATE:
the break-in alarm, which would sound if one of the doors were opened
the optional interior motion and inclination alarm sensors.
Doing so would DEACTIVATE:
the sunroof and interior courtesy light controls.
the central locking buttons on the front door armrests, although the interior door handles would still function to
allow occupants to leave the car.
Disabled features would remain disabled until the remote were used again to unlock the car.
In addition, locking an occupied vehicle would hinder rapid access to the occupants in an accident or emergency.
Replacing the battery in the remote control
If the range of the transmitter is noticeably reduced, this indicates that the battery is weak and should be replaced.
To replace the battery
Remove the screw on the transmitter cover with a small screwdriver.
Remove the cover carefully pressing it rearward/upward.
Replace the battery with a new 3-volt, CR 2032 battery. The battery should be inserted with the minus side upward.
Avoid touching the contact surfaces of the battery with your fingers.
Reinstall the cover and tighten the screw to help protect the transmitter.
