How to lock a bike, 2 extreme cases
(f2.tchncs.de)
Pictured above: a bike locked badly to a good quality rack. Just a wrench, and a thief takes the wheel and bike away.
In the photo below: my solution to properly lock a bike to bad, low rack made wrong (to “dish rack”, outside Decathlon 🤦). Instead of inserting the wheel, I put the bike across the structure, so I can easily lock wheel and frame.

In the first photo, the lock is attached to the rack and to the bike's fork only. If you remove the front wheel, then neither the bike nor the wheel is attached to the lock anymore.
The second one has the bike placed "wrong" on a bike rack so that they are able to lock the wheel and the frame to the rack.
