Door fit
Lumive Simplex V1 is an adjustable replacement cylinder for 60-90 mm doors. Nuki Smart Lock Pro (5th Gen) clips onto the existing cylinder inside the door instead of replacing the cylinder or mortise. Compatibility depends on an existing Europrofile or selected Swiss Round cylinder, not a published thickness range.
Nuki Smart Lock Pro (5th Gen) measures 57 mm by 70 mm, but module size is not cylinder length. Use the manufacturer’s checker; confirm the Simplex V1 measurement and replacement format with Lumive.
Measure first:
- Measure the full door thickness at the cylinder position.
- Photograph both door faces, the door edge, the current cylinder, handle, and surrounding hardware.
- Identify whether the cylinder is Europrofile, Swiss Round, or another profile.
- Check inside clearance for the selected hardware and handle movement.
- Use the manufacturer’s checker for Nuki Smart Lock Pro (5th Gen); confirm Simplex V1 measurements with Lumive.
Send measurements and photos to Lumive before ordering. For product-specific fit confirmation, use the smart door lock range.

FAQ
Will Lumive Simplex V1 fit my door?
It is an adjustable replacement cylinder intended for 60-90 mm door thickness, but thickness is not the only fit check. Measure at the cylinder position, identify the existing profile and surrounding hardware, and photograph both faces and the edge. Send those measurements and photos to Lumive before ordering so the replacement format and clearance can be confirmed.
Does Nuki Smart Lock Pro (5th Gen) replace the cylinder?
No. Nuki Smart Lock Pro (5th Gen) is an interior retrofit module that clips onto the existing compatible cylinder. The manufacturer lists Europrofile and selected Swiss Round cylinders and provides a compatibility checker rather than one door-thickness range. If mechanical-key fallback matters, confirm that the existing cylinder has the required emergency and danger function.
Are fingerprint and keypad access included with both locks?
Lumive Simplex V1 includes built-in fingerprint and keypad access, along with 5 RFID cards and 2 mechanical backup keys. Nuki Smart Lock Pro (5th Gen) uses its app and Auto Unlock as built-in methods; PIN and fingerprint entry require the separately purchased Nuki Keypad, and push-button access requires the separate Fob.
Can I unlock either lock remotely?
Nuki Smart Lock Pro (5th Gen) has built-in Wi-Fi for remote access without a separate bridge and also offers Nuki Web after account setup. Lumive Simplex V1 lists Mobile App and remote among its six access methods, while its stated connection is Bluetooth. Confirm the exact remote-use requirements with Lumive before ordering.
What happens when the battery is low or empty?
Lumive Simplex V1 uses 3 pre-installed 1.5V AAA batteries and provides a Type-C emergency-charging port plus 2 backup keys. Nuki Smart Lock Pro (5th Gen) warns below 20%, uses a built-in non-removable lithium-ion battery, and charges magnetically. Confirm a working fallback, especially the existing cylinder’s emergency function, before relying on mechanical-key access.
What capacity and weather rating should I expect?
Simplex V1 is specified for indoor use, but confirm its fingerprint, password, and total user capacities with Lumive before ordering. For Nuki Smart Lock Pro (5th Gen), check the manufacturer’s page for user, PIN, fingerprint, and weather-rating details. Do not infer either lock’s capacity or environmental resistance from a related model.
