To properly utilize a bike lock, there are a few key steps to follow. First, you should lock your bike to an immovable anchor point, such as a bike stand or railings, and make sure the bike and lock cannot be lifted over the anchor point (source: [Bikeradar](https://www.bikeradar.com/advice/skills/how-to-lock-a-bike/)). Second, you should use a high-quality lock, such as a D-lock, which is hard to attack (source: [Cyclingnews](https://www.cyclingnews.com/features/how-to-lock-a-bike-tips-on-proper-practice-to-prevent-bike-theft/)). Third, you should size the lock so that it goes around the things you’re locking with as little gap left as possible (source: [REI Co-op](https://www.rei.com/learn/expert-advice/bike-lock.html)). Finally, you should make sure to lock both wheels and the frame of the bike to the anchor point, or at least one wheel and the frame if you can’t lock both wheels (source: [wikiHow](https://www.wikihow.com/Lock-Your-Bike)).
To utilize a bike lock, you need first to look for a stationary object like a pole or a bike rack and then wrap the cable around it.
Insert the lock cable into the hole on the lock cylinder. Attach the lock through your rear wheel. Make sure to lock it to a hard object.
