Peace be upon you, I have a smart door lock that I bought for my house for 400 SAR. I haven't installed or used it at all. It's new in its box and bags, as shown in the pictures. I want to sell it for 300 SAR due to no need. Its most important features in brief: • Opens in 5 ways: (fingerprint, passcode, card, regular key, and mobile app). • Works with regular batteries (AA), not an internal rechargeable battery. This is an advantage so it doesn't get damaged or worn out over time; you just change them when they run out. • Temporary passcode feature (excellent for guests or delivery workers). • Withstands high heat and is resistant to rain and dust. • It has a charger port (Type-C) for emergencies if the batteries run out, and you can lock it from the inside with a safety lock.
