where in las vegas can I find a key lock for the passenger side of my colorado. on 2006 Chevrolet Colorado

It only locks and unlocks from the inside and cannot be opened from the outside. Dumb, but true

No that isn't it. It came this way. Others have said so too. It has no way to open it as it has no place for a key in the handle.
