You have to have a key with the chip. Shut the hood and trunk, lock all the doors. If you have a key fob, try it first. That should disarm the security. If not lock it again and unlock the passenger side door with the key. Reach in and unlock the drivers door by the handle. If this works then your key switch on the drivers side is bad. That's why the security sets. Some times they just fall off the lock. They're made of plastic. If all that fails, your looking at a reset. That would be a locksmith or the dealer.
