A guy I work with went into a store, did not find what he wanted, came out, and his 2006 F-250 was gone. Friends that live in Phoenix tell me that it takes a car thief 30 seconds to 'own' a Ford Thooper Duty. Holy Feces!!!!, made me think twice about leaving the truck.
I know the 2011 has a transponder key... so I checked.
•Engine Immobilizer: To help protect the vehicle, the mobile hub for all this personal information, Ford depends on SecuriLock. This patented passive anti-theft system prevents the engine from starting unless a coded ignition key is used. With SecuriLock, a wireless radio-frequency transmission is required to transfer an electronic code between a transponder in the key to the vehicle's ignition system. There are 72 million-billion possible codes so every Ford vehicle sold worldwide for the next 10 billion years will come with a unique code.
Soooo.. without 'THE' key, the thief is limited to stealing contents...the vehicle remains immobile...
(not sleeping in the truck anymore

at least for 9.99 billion years..!)
(
personally...I understand why they hung horse thieves...)
