Upon first use, the lock will have a default master code (refer to the quick programming manual for the default code). It is highly recommended to change this immediately for security purposes. Follow the instructions in the quick programming manual to set your new master code.
5.2 Adding User Codes
The master code is used to add or delete user codes. You can program up to 50 unique user codes for family members, guests, or staff. Refer to the quick programming manual for detailed steps on adding user codes.
