Can locksmiths change new locks to work for an old key???

I need to buy a new ignition switch and a new lock on the glove compartment for a car.....



But when i get these replaced i dont want to carry around a seperate key just to turn on the car...



so my question is...

can a locksmith or someone else change the key settings of the new locks to match my original car key?.....



the car is a 1994, so it doesnt have those micro chip keys.....Can locksmiths change new locks to work for an old key???
