Valet Keys?

I have a `94 Isuzu Rodeo and I need to know if the vehicle was sold originally with Valet Keys or if I have the original key which is supposed to work everything! I looked in the owners manual and did not see any information on such a thing but neither did my GMC!

Bare in mind the key I have does work the doors and the glove box and goes into the rear lock of the vehicle...

anyone know the answers?

Thanks in advance,
Perry

Nope, no valet key.
