My dad put the child proof lock on and now the rear door wont open at all help 2009 f 150

Hit the door lock with the remote or dr. side will lock all the doors so they won't open from the outside. If you open the rear doors, on the outside edge of the doors is a lever that will allow the rear doors to operate from the inside. Hope that helps

Open the rear passenger door and you will see a switch by the locking latch. Turn it off.

page 14 of your owners manual shows how to lock unlock the child proof setup on door -----open door and by latch will see the the lock move to unlock position ! CAUTION LOCKING WITH REAR DOOR CHILDPROTECTORS Turn the lock knob to the "LOCK" position as shown on the label. This feature allows you to lock a rear door so it can be opened from the outside only, not from inside. We recommend using this feature.... the link is a copy of your owners manual

Your Tempo is equipped with early child-proof rear door locks...(cannot open from the inside when locked) Open the doors from the outside and look near the door catch for a small switch that moves back and forth...if still labeled it should show "Lock...Unlock" marks...leave on unlock for normal opening from inside. Hope this helps.

If your back doors won't open from the inside then the child proof locks maybe turned on. Open the door from the outside and look at the edge of the door near the lock for a small lever or screw setting for the child proof lock. Tun off the child proof lock and then you can open the back door from the inside.

Open the door and look at the back edge of the door by the latch there will be a small sliding lever to enable/disable the child lock.

Your rear doors have a child proof safety lock above the lock linkage, there is a turn knob, open the door from the outside and adjust, then the door will open from the inside now.

Locking the vehicle will lock it from the out side.
If you are trying to child proof your rear doors, when you open the doors, on each of the rear doors there should be a little button you can move to lock the rear door from the inside.
Please let me know if I can further assist you.

I have a bunch of 94 rodeos, and the locks are normal, up and down type, The driver's door locks the whole car. The rear and passenger only lock themselves, from the inside, from the outside, you have to hold the handle up. The driver's door will lock the whole car but you have to hold the handle up to lock the door. otherwise they all open again.I always use the key on the driver's door. If you are talking about the child proof lock on the inside of the door, it just flicks up and down. The rear door is opened when the glass is up. You have to unlock the glass either from the dash or the key in the back. Hope this helps.

Took off inside door panel and flipped the child proof lock. Mechanism for entrance from outside handle broken. Replacing it.
