Digital password residential dead bolt lock

This is our SDBD-BC2000 dead bolt lock. You have a master passcode. From that, you can create up to 20 user passcodes. You can add and delete passcodes individually or all at once. You can also create a 1 use passcode. The master code offers the ability to do all these functions. This is a brushed Chrome finish and is tested and used in residential applications.
