A push-pull lock opens the way a door should: authenticate, then push to come in or pull to go out — the handle itself is the release, so there is no turning a knob with a hand full of shopping. The DG 400 takes a fingerprint from any angle, a card, a PIN or a mechanical key — four ways in, with up to a hundred fingerprints and cards on file.
It runs on ordinary AA batteries, so a flat set is a trip to the shop rather than a service call, and a drained battery is revived from outside for the moments it takes to get in. Dual authentication can ask for two credentials at once.
Every model raises an alarm on a forced door, a fire, a flat battery or a lock left disengaged, and offers an auto-locking mode that secures the door behind you and a privacy mode that keeps the outside handle dead while you are home.
