Is an ignition lock reuseable?

Thank you for the information, Directions are very helpful, I was going to order from Dante's Mopar Parts, heard good things about them. As far as trouble shooting, this is a none OEM ignition, I am using a Pertronix dist., and there matching coil, no resister block used, I have the Igni 1 and Ign2 hooked together, When I crank the car it seems to want to fire up, but when you leave the key go to the run position is just dies, that is what makes me think I am losing Igni 1 or Igni 2 from the switch.
