Frame lock that can lock without key inserted

I've seen these advertised recently:

You can lock them without using the key, and allegedly they are super mega secure.

Abus has several frame locks: https://www.abus.com/uk/Mobile-Security/Bike-Safety-and-Security/Locks/Frame-Locks

They distinguish between 2 variants. For one variant, you can remove the key when the lock is unlocked. The other variant does not allow you to remove the key when the lock is unlocked. However, I am not sure, whether or not you can lock it while you have the key removed. But maybe the variant where you cannot remove the key would already help you, as you can never forget to take your key with you.

You should note that non-key-retaining locks that don't involve a separate lock-actuating lever are susceptible to shimming.

Before buying a lock, you should always google or YouTube search to see if your lock can be easily shimmed or bypassed.

Ps I would not worry too much about picking unless it's a tubular lock, as most thieves will prefer to use physical force (cutters, grinder) as they are much faster (5-30 seconds) than picking (1-5 minutes in ideal circumstances; 3-20 in non-ideal).
