With the key. No key? Take your proof of ownership to Ford and pay them to make new keys.

I think the anti-lock system went on my truck ? How do we get into the truck ? Even though we put the key into the ignition, the truck doesn't want to start ? Is there a certain way to deactivated the truck ? The Anti-Lock system activated ?

You probably have a security system issue. Did you try another key? Are you sure it is a a security system issue and not another problem? Does the engine turn over or is the battery dead?

The key doesn't want to turn over ? There's no power, nothing ? Anti-lock system indicator lights is on flashing ? How can I restart the truck ? Need assistance ?

After entering the truck from the drivers, manually if needed, try to start the truck. If still nothing, cycle the lock and unlock switch a couple of times from the door panel then try to start. If it is a security feature you will have to bring it to Ford. Few outside shops want to mess with those features
