It's possible you need key coded keys to start engine. If key is not coded security system will not allow engine to start. You need one original key that works to get others made.

What I suspect is the previous owner lost a key and had a regular key cut without knowing a programmable key is required to start the truck. Since you lost the main key, you have to have the vehicle taken to a dealership, or find a locksmith, who can cut a couple of keys, program them, then possess the proper electronic equipment to reprogram the computer within the vehicle.
