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 ### ⭐⭐⭐⭐⭐ Great product! *by J***W on 29 November 2022* This is so easy to install and makes life so much easier. I wish I’d got this sooner. It took me less than 10 minutes to install and the app works perfect. There’s also a back up mechanical unlock feature which works perfect. I wish it was a bit cheaper as I’d fit one to our garage door too. Hopefully they’ll come down in price. The quality is fantastic and feels well made. One slight issue seems to be when my partner and I return home together, the lock won’t automatically open but does when we arrive home separately. ### ⭐⭐⭐⭐⭐ Super secure *by T***N on 18 August 2023* I was worried about buying one of these, but after a few days im blown away how good it is, walk up to my door with nothing in my hands, and the door activates for 10 seconds, enough time for me to open and im home. You can set timer for longer if needed. Very easy to operate and never use my phone, no need. Press inside button when I leave so I can lock as I leave and just walk to enter. Soooo good !! ### ⭐⭐⭐⭐⭐ Works perfectly *by B***. on 10 March 2024* Had this installed for 2 weeks now works perfectly, geo is brilliant, and very easy to install ## Frequently Bought Together - Bold Smart Lock - Keyless Smart Door Lock - Silver (SX-43) - Bold Connect Bundle - SX-33 Bold Smart Lock Cylinder --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pt/products/339948183-sx-43](https://www.desertcart.pt/products/339948183-sx-43) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-30*
