Are there two sets of keys on a 1993 Chevy Silverado C1500 V6?

Just bought a 1993 Chevrolet Silverado C1500 truck, But the key doesn't seem to work for the door locks, Is there another set that came with the truck originally for the door locks?

My buddies 91 had separate keys for the door and I believe The gen changed in 95 so yeah I think u hav two sets of keys
