    It may be that the original key has something in common with the key that should not have been called, the outline of the original key should also have this key, and the second key should lack some hope in addition to the outline on the original key.

    There are two keys when decorating, and the decoration key can not be used after the slot is opened. Your two keys are the same teeth.

    One is reserved for the use of decoration workers, when the decoration is completed, the owner uses the normal key, the previous one is invalid, saving the owner to replace the lock!

    One is for decoration, and your lock is not adjusted after the decoration, so it can still be opened. After getting it, you won't be able to use the decoration key!

    I don't know what to say, so I'm going to ask someone else!

    Give the slotted to the decoration team, and you can use the slotted one after the decoration is completed. As long as you have used a key with a slot, you can't use it without a slot, remember.
