1994 Chevy Silverado Door Key Needed

I recently purchased a 1994 Silverado 4x4 ext cab and the ignition key was broke off in the switch and I had to replace the lock and tumbler today as even a professional locksmith could not remove it. The previous owner(one owner, WOW) could not find any door keys. I was needing to know where to get one or if my truck is equipped with the keyless entry option and I could buy a key fob. Any ideas would be greatly appreciated.
