＜What you need to prepare＞

- A "minus 2.4 mm" or "minus 3 mm" precision screwdriver set sold at 100 yen shops

<How to attach the key>

1. Insert the shaft from the outside of the metal fittings, and place the leather part, smart key, key, leather part, and metal fittings in that order.
2. Insert a precision screwdriver into the flathead screw hole and turn it.
3. Once you have loosened the screw shaft, insert the key and then tighten the screw again to complete the lock.

*Please be careful not to insert the screw too forcefully, as this may damage the tip of the screw or cause it to break.

＜！Caution！＞

1. Please be careful not to turn the screws too hard as this can cause the tips of the screws to chip and become loose.
2. If you are concerned about loosening during use, you can reduce the loosening by applying a small amount of thread-loosening prevention agent or, as a substitute, nail top coat, instant glue, or wood glue to the screw holes and then tightening the screws and leaving them for a while.
3. There may be scratches on the metal fittings, but these are a natural part of the process, called "Tsurushi", which is used during the high-quality plating process for domestic metal fittings. After that, we apply a polishing process.
4. If the screw part is blackened, this is due to seizure during the metal engraving process. Since the screws are tightened during plating, the plating is not applied to the base. This is not rust, so there is no problem with using the product.
