Re-keying SmartKey locks requires only three items and entails three easy steps. Users must have their functioning key, a SmartKey Learn Tool, and a new Kwikset key. First, insert the functioning key and turn it ¼-turn clockwise. Then, insert and remove the SmartKey learn tool. Follow by removing the functioning key, inserting a new key, and turning it ½-turn counter-clockwise. Your lock is then successfully re-keyed.
