Locks and Security CHILDPROOF DOOR LOCKS Childproof door locks prevent opening of the rear doors from inside the vehicle regardless of the state of the main locks (locked or unlocked). The childproof locks are located on the rear edge of each rear door and must be set separately for each door. Setting the lock for one door will not automatically set the lock for both doors. Move lock control up to engage the childproof lock. Move control down to disengage childproof locks.
