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?
