I got a Kwikset deadbolt lock (has key hole on both sides instead of key hole externally with latch internally). This lock uses SmartKey technology so you can rekey the lock to use a new key rather than having to replace the lock itself.
After I installed it, I wanted to rekey the lock to use my hold house key until my roommate got home so I could then give her the new key, after which I would rekey the lock to use the new key. While rekeying with the SmarkKey in the hole, I found that my old house key was too big for the Kwikset lock and would only go in half way, so I pulled it out. I then tried using the key that originally came with the lock and now it doesn't work on the inside where I was attempting the rekey, but it does work on the outside.
In order to rekey these locks, you have to insert a working key, give it a quarter turn so the key is horizontal, insert the SmarkKey, take out the current key, then insert the new key. Since no key will work with the inside lock, I can't get it to turn at all.
Am I going to have to disasseble the lock to fix this or is there another way?

take the lock to your local home store that carries this line of locks. they will remove the core and put it in a SmartKey Reset Cradle. this returns the lock to an unprogrammed state.
there is no way to do this yourself without disassembling the lock core, and there's about a bazillion point 2 pieces in there.
