The Lion Head Rathdowne is a compact digital entrance lock with a doorbell function. It opens by fingerprint, PIN code, card or fob, the phone app over Bluetooth, or a backup key. WiFi is not built in, so remote access through the app needs a Lion Head WiFi gateway. It suits hinged doors 35 to 65 mm thick and works with a tubular latch or a mortice. Locksmiths Perth 24/7 supplies and fits it anywhere in Perth, Western Australia.

Who the Rathdowne suits
The Rathdowne is the short one in the Lion Head entrance lock range, at 193 mm tall. It suits a front door where you want something neat rather than a long plate, and Lion Head lists a doorbell function on it.
It holds 200 fingerprints, 150 PIN codes and 200 cards. That is plenty for a busy family, or for a holiday let host who hands out a code to each booking and wants the app working from home with a gateway.
What we check before we fit it
- Backset. On a Lion Head 85 series mortice it can be set up at 45, 50, 60 or 70 mm backset, so we measure from the door edge to the centre of your current lock.
- Lock body. It also works with Lion Head tubular latches and its 5050 and 6050 mortice locks. It is sold without a lock body, so we choose the one that suits your door.
- Old holes. Because the plate is short, it may not hide the marks left by a long old handle. We check that before you choose it.
- Door thickness. 35 to 65 mm.
- Weather. IP55 on the outside part only, so a door under a porch or verandah is best.
Living with the Rathdowne
- Batteries. 4 AA batteries, up to 12 months depending on use, according to Lion Head.
- Flat batteries. Use the USB C port with a power bank for emergency power, or the backup key.
- The app. It works by Bluetooth up close. Away from home you need the Lion Head WiFi gateway.
- Hot days. Lion Head rates it from minus 25°C to 60°C.
Rathdowne or Nicholson?
Same ways to open, same door thickness, same user numbers. The Rathdowne is shorter, at 193 mm tall against 234 mm, and has the doorbell function. The Nicholson has a bigger plate that hides more of an old lock. See the Lion Head Nicholson.
