You will need to purchase another from VW.
These keys are programmed to the car.
however you can purchase an aftermarket key set, but you will have to reprogram the car ECM to the new key set.
I alway recommend a set from the dealer, it keeps up the value of the car, and you don't have an issue returning a aftermarket key set if you have issues. The dealer will take good care of you.

Try locking and unlocking the rear tailgate lock with your key. That should turn off the factory security system. As for the keys, if you no longer have a key with a 'chip' in it, the vehicle will not stay running, until you replace the 'chip' key. The immobolizer system needs a key with a 'chip' to work.

They key has a compter chip that inplanted in the key. A dub key wouldn't work. Take your title or registration with some form of picture id to any GM dealer and the would be able to make you a key. It will cost a few bucks, prices vary.
