The usage is very simple. The user just needs to hold the coin horizontally and turn it around the "screw" a few times, insert the key, and then tighten it again. (After knowing the specific position of the key, the person opening the door won’t have to try one by one, right?) Additionally, this product isn’t limited to keys; depending on the user’s preference, it can also be used with USB drives or RFID chips.
1. The inner diameter of the column is 4 millimeters. Please ensure that the inner diameter of your keyhole is greater than 4 millimeters; being much larger is fine.
2. The standard inner column is approximately 11 millimeters high (it can hold 4–5 ordinary keys). If you have special keys, please measure them in advance.
3. The cross-shaped key can be installed (with a thickness equal to that of 3–4 ordinary keys). The black rubber head key can also be installed, either directly or by melting the plastic with an soldering iron.
