There are actually two "protection modes" in the ALP. Privacy Protection and Theft Protection. They are different service codes but work similarly. Both put a key file on the USB which is then required for the unit to function. The difference is how the unit responds without the key: in Privacy mode it'll only function as parking sensors, in theft mode it won't function at all, or power up without the key.

The Theft Protection isn't documented anywhere except in the FAQ on the AL site.

Once either of these are enabled there's no way to remove it, so I don't recommend most people use them unless they really need to.
