The easiest way is via the app; however it can also be done manually on the handle. Please see the instruction manual or ‘How To Videos’ here for clear instructions.
App: Open the app whilst in Bluetooth range of the handle, touch your displayed handle, then touch ‘Users’ and choose which user you want to assign it to. You can see the fingerprints or Key cards already registered to the handle, simply click ‘Add’ under either ‘Fingerprints’ or ‘Key cards’. Follow the instructions and name the fingerprint/key card.
Handle: Push the set button (located on the inside handle under the bottom cover). Then either: press your fingerprint (at the top of the external handle) 4 separate times, in 4 different positions, OR; present the key card/fob to the reading area (just above the lever on external handle)
