## Questions & Answers

**Q: Does the lock use the home WiFi or is it solely based on Bluetooth?**
A: The device itself is Bluetooth but you can get the hub add on and connect it to the Wi-Fi so you can open the lock from anywhere

**Q: What is the width of the main unit on the inside? Our door handle is very close to the frame - most smart locks are too big to open the door!**
A: Hi,

The diameter of the inner knob is 47mm. You will need 23/24mm next to the keyhole to make the Bold fit.

Best,

Karim

**Q: Can you use fingerprint to operate device**
A: Only to unlock the App. Not on the device

**Q: Could someone please provide the measurements of outside knob? Thanks!**
A: Its a matter of trial and error specially with bold

Their measurements are inaccurate. I tried from the smallest SX35, 45 and even 55. 

It’s difficult as with bold its only one side you can adjust. I ended up returning all of them.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent Replacement Smart Cylinder
*by S***K on 3 May 2022*

The media could not be loaded. Great lock! The proximity feature is poor.... its only worked once since I've had it, and disabling notifications doesn't seem to stop notifications when re-entering the 200 meter radius to your front door, and you get notifications about "activate the lock now?" despite the door not even being locked as other people are already home. So it has minor "quirks", but overall I'm very impressed by it! I can give permission to anyone, and even state whether its permanent or temporary access. It's only the cylinder section so has no ability to auto lock the door for you, but that's fine for me. The Bold Connect optional add-on does allow for remote unlocking though!It was the only smart lock with SKG*** security rating (the highest possible) that I could find. This high rating is "lost" if you enable the cylinder pin entry feature (should you leave your phone at home, you could use the cylinder like a safe combination) but you're advised not to enable that for the extra protection/security.Installation was a doodle, but measuring or getting the right one was a little tricky. I first got the SX33 which just about fitted but was far too tight. I sent that back and got the SX45 and that's brilliant! Doesn't stick out too much, and freely turns with ease.I've contacted Bold customer support 3 times now with various questions, and they get back within a couple of days and all the answers are satisfactory and given me more confidence at the high security of this lock!

### ⭐⭐⭐ Very solid looking lock but the software isn't quite there yet
*by C***R on 4 April 2022*

The lock itself works fine although it cannot actually tell you if it is locked or not only whether it "could" be activated. The software has a bluetooth proximity function but this does not unlock the door, it just pops up a notification that it knows you are near the door, clicking on the notification opens the app and allows you to activate the lock which will then allow you to turn the outer knob to unlock the door. Most times for me, the app had stopped working in the background on my phone so the notification only appeared if I then opened the app (bit pointless by then). I like the lock itself and it looks very well made but in hindsight, I should probably have gone for something zigbee or z-wave enabled and probably fingerprint activated. There is a wifi gateway available but the price has put me off and I hate having ever more hubs when locks like this should just pick zigbee or z-wave and stop inventing proprietary methods of allowing remote access.

### ⭐⭐⭐⭐⭐ Seems good
*by E***N on 23 January 2022*

This was very easy to install, no different to any other euro lock cylinder. Software was easy to setup on both IOS and Android devices.We've had it a few months now and it seems to work very reliably. Looks OK, just a bit bulky, indoors. The outdoor side is unobtrusive.
