What is the code in the key from the intercom?

So. The question is asked incorrectly.
Let's start with what I know. The plant fits in the key access code. This code fits into the intercom. When you contact key intercom key intercom sends some kind of code. Actually a question: what is the code (numbers and letters)? Unfortunately, this is all I could dig up on the Internet for this reason.
