Is the ignition key and door same in a 2007 Chevy silverado?

No, the ignition key and door key for a 2007 Chevy Silverado are not necessarily the same. While they *can* be the same key (meaning one key operates both), it's also common for them to be different. Many Silverados from that year had separate keys for the ignition and doors, especially if the truck had additional locking features or aftermarket additions.
