Toyota Repair: Trunk lock, 2007 toyota camry, toyota camry

Question
I have a 2007 Toyota Camry. The manual told me how to set the luggage security system so that the inside latch and key would not work. It does not tell how to undo this process. Now the lock on the trunk is in the horizontal position, I cannot use the key in the trunk lock and I cannot utilize the latch on the inside. How do I undo this feature?

Answer
You should have two keys, one master key and one valet key, the master key locks/unlocks all locks, the valet key will only work on the doors and ignition. The master key is black, the valet key is gray, make sure you are not using the valet key to try to open the trunk.
