The information below is based on Apple's support article: How to generate a recovery key - Apple Support with quoted excerpts.

A recovery key is designed as an alternative to Account Recovery ( https://support.apple.com/kb/HT204921) which is where Apple helps you regain access to your account. However, "when you generate a recovery key, you can't use account recovery." You can try to contact Apple (see: Contact Apple for help with Apple ID account security - Apple Support ), but to me the previous statement implies that setting up a recovery key excludes Apple from being able to do anything. Apple says: "Using a recovery key is more secure, but it means that you’re responsible for maintaining access to your trusted devices and your recovery key. If you lose both of these items, you could be locked out of your account permanently."
