A rekeyable lock includes a lock cylinder, a plug, a pin assembly and a stopper, the lock cylinder comprises a plug hole, a plurality of upper pin holes and a lower-pin-replacing hole, the plug is disposed at the plug hole, the pin assembly comprises a plurality of upper pins and a plurality of lower pins, the lower-pin-replacing hole selectively reveals the lower pins, the stopper is utilized for plugging into the lower-pin-replacing hole. When the stopper separates from the lower-pin-replacing hole, the lower-pin-replacing hole reveals the lower pins so as to replace the lower pins rapidly. When the stopper plugs into the lower-pin-replacing hole, the width of the stopper equals to that of the lower-pin-replacing hole. Otherwise, when the stopper separates from the lower-pin-replacing hole, the width of the stopper is larger than that of the lower-pin-replacing hole. |
