Peace, mercy, and blessings of God be upon you. I have one used, lightly used, for 150 SAR. And I have 2 new smart locks in their boxes. It only fits wooden doors and is not suitable for external iron doors. I can also explain how to operate it upon purchase and control adding a remote entry code via mobile. I will also provide you with a Pakistani person who will install it inside Buraydah. The sale is by offer within Buraydah.
