The right smart lock matches your door’s measurements and existing preparation. Start with mortise options for a 4585 body, a cylinder retrofit when replacing the cylinder, or a rim lock for surface mounting. Confirm thickness, pocket, backset, handing, and outdoor exposure before ordering.
Start with your door
Door material alone is insufficient; complete this checklist:
- Measure door thickness at the lock. Guardian G1 supports 35-55 mm; Simplex V1 adjusts for 60-90 mm doors. Do not transfer either range to another model.
- Measure the lock body or mortise pocket. Record its height and depth. Treat 4585 as a body designation, then send the pocket, backset, and centres measurements to Lumive for confirmation before ordering.
- Measure the backset. Record the distance from the door edge to the handle or cylinder axis, then send the measurement to Lumive for confirmation before ordering.
- Identify cylinder length and installation type. V1 is an adjustable cylinder; G1 and G12 are mortise locks; SafeGuard is a rim lock. Measure an existing cylinder’s full length and its split around the fixing screw.
- Record handing and material. Note hinge side, inward or outward opening, and whether the door is wood, metal, or glass. For glass or metal doors, send photos and measurements to Lumive for confirmation before ordering.
- Check outdoor exposure. G12 is IP55 and rated from -25°C to 60°C. V1 is indoor-only; confirm SafeGuard’s outdoor suitability with Lumive before choosing it.
Send Lumive measurements and photos of both faces, the edge, and current lock. Browse the smart door lock range, but obtain fit confirmation before purchase.

FAQ
Is door thickness enough to choose a smart lock?
No. Thickness can eliminate options, but it does not prove that a lock body or cylinder fits. Measure the current pocket, backset, cylinder length, material, and handing. For G1, check the 35-55 mm range and 4585 body, then send the backset, centres, measurements, and door photos to Lumive for confirmation.
What happens to the lock during a power cut?
Power details are model-specific. G1 uses 4 AAA batteries, while V1 uses 3 1.5V AAA batteries. Before ordering G12 WiFi or SafeGuard, confirm the power arrangement with Lumive, and do not assume that a battery type or count from one model applies to another.
How do I enter if the battery is empty?
The emergency route depends on the model. G1 lists an emergency power port and mechanical-key fallback. G12 WiFi and V1 have Type-C emergency power, and V1 includes 2 backup keys. Before purchase, confirm SafeGuard’s emergency route with Lumive. Keep the relevant key or external power source somewhere accessible outside the locked room.
Which lock suits heat and an outdoor door?
G12 WiFi has IP55 and a -25°C to 60°C operating range if the door measurements and direct exposure match your use. That does not replace pocket and thickness checks. V1 is explicitly for indoor use; before placing SafeGuard outside, confirm its outdoor suitability with Lumive.
What works for a rental or Airbnb unit?
Start with the door, then the management method. V1 offers app access over Bluetooth and needs a separate gateway for remote unlocking; G1 supports app remote unlocking over Wi-Fi; and G12 WiFi uses the Lumive App. Choose only after the measurements match, then verify that the available access methods suit your guest handover without assuming unlisted functions.
Who can install the lock?
You can book Lumive’s paid installation service in the listed cities. One lock costs SAR 199 as a standalone service or SAR 150 with a product purchase under the store policy. Before booking, send photos of the door, its edge, and the current lock, and mention if the door is metal so the technician can review fit and required work.
What if the lock does not fit my door?
The store states a 14-day return policy, but prevention is better than discovering a mismatch after delivery. Do not cut the door or alter the lock based on a guess. Keep the packaging, check the return terms, and contact Lumive with photos and measurements. For a new order, obtain fit confirmation for thickness, pocket, backset, and handing first.
