・Qrio Lock Body ・Optional Remote Control ・8 unused batteries included This is a total of 3 items. I was using it without any problems until recently, but I am selling it because I switched to a different lock. I was using it without any particular problems, but when I attached it to the door before, the adhesive of the double-sided tape weakened, and the knob part came off when it fell off, so I repaired it and used it. After the repair, it worked without any problems and did not come off. Also, after that, to prevent it from falling off, I used double-sided tape and sealant together to prevent it from falling off, so there is some sealant residue on the mounting surface, but it can be removed by rubbing. When installing, you can use double-sided tape as usual, and it can be used without any problems. For the above reasons, I have lowered the price a little, so please purchase only if you understand. #Qrio Lock #Qrio Lock #Smart Lock #Smart Home
