Bike stolen, lock snapped apparently without any tools needed. See german reviews. DO NOT buy this. **Q: Hi, please help! I have tried to set new password according to instructions, set it at 00000 (original password) turned know to the right but no luck** A: Don't worry, if you forget your code yu can simply snap the lock with your hands. An excellent feature to unlock quickly, not so good if someone wants to steal your bike. Do NOT buy this lock. **Q: Is this lock bolt cropper proof?** A: It will not even withstand someone snapping it with their hands. See video in german review **Q: I changed the password and now cannot open the lock? where am i going wrong** A: I am afraid that your first mistake was buying the lock. If it is stuck shut you can snap it open with your hands. See the video in the german reviews for how to do this. It is how my bike got stolen. This lock is not good value when your bike gets nicked. ## Frequently Bought Together - SPGOOD Bike Locks Heavy Duty/Bicycle Chain/Cycling Lock (14 Colors) 5-Digits Codes Resettable 100,000 Codes for Bike Cycle, Moto, Door, Gate Fence 830mm Length(Black) - Favoto Bike Helmet Bicycle Helmet Lightweight Cycle Helmet for Adult Men Women Cycling Road Mountain Bike MTB Helmet Safety Protection Adjustable Size 58-61cm - Glangeh Bike Lights Ultra Slim, Rechargeable Bicycle Lights Front and Rear, 4+6 Modes Bike Light, Waterproof IP65 Cycle Lights for Road Safety, 1.5 Hrs Fast Charging Bike Light Cycling Headlights Set --- ## 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.jp/products/174364706-spgood-bike-lock-with-combination-bicycle-lock-with-hardened-chain](https://www.desertcart.jp/products/174364706-spgood-bike-lock-with-combination-bicycle-lock-with-hardened-chain) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-16*
