Tightening the bolts on the cylinder so that the existing door pull around the external face of the lock gripped the door made turning the key from the outside a bit stiff but seems to be getting slicker with use. You can trim the length of the fixing bolts with a hacksaw so perhaps mine are a fraction longer than they should be. **Q: Lock fitted but the night latch wont move even when key is used it will push in with your fingers but does not seem connectedfrightened to shut door a** A: It seems to me that the unit must be defective. I have fitted 2 of these and had no problems! Send it back! **Q: Can you confirm dimensions of the actual lock please.** A: HI,Width is 60mm, Height is 80mm, Thickness 25mmKind RegardsAhmed **Q: Is this chrome or brass as 2 different colours shown** A: If this was the site I ordered from they had the option for either. I wanted the chrome and it arrived within 2 days, excellent service. ## Frequently Bought Together - Yale B-2-BLX-PB-40 Double Locking Nightlatch, 40 mm Backset, Brass Finish, High Security, can be Locked from Inside with Key, Brasslux - Yale P-110 Cylinder Pull, for 3.2cm cylinder diameter, Polished Brass Finish, Standard Security, Visi Packed, suitable for Wooden doors --- ## 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.hk/products/216168292-b-2-blx-pb-40-double-locking-nightlatch-40-mm](https://www.desertcart.hk/products/216168292-b-2-blx-pb-40-double-locking-nightlatch-40-mm) --- *Product available on Desertcart Hong Kong* *Store origin: HK* *Last updated: 2026-10-16*
