The lock is used.. it works perfectly but its fingerprint is unknown.. I rented an apartment and found it installed.. I installed a AAA battery, the same battery as the receiver remote, and it works 100%. It fits on wooden doors directly in place of the cylinder without any drilling. It needs a factory reset, but I don’t know how to do it.. There is a QR code sticker on the inside. I searched for it, and its new price is around 340 Riyals.
