You lost your key to dodge truck can the dealership make one from VIN number?

No, a dealership cannot make a new key for your Dodge truck solely from the VIN number. The VIN provides information about the vehicle, but it doesn't contain the key's cryptographic information needed to create a new one. Dealerships (and locksmiths specializing in automotive keys) need additional information, typically found on the key itself or a related key fob, to program a new key. They may also need proof of ownership.
