High Security = Low Security

I certainly do that with my 4 digit CC PIN that was the one originally provided by the bank.

So what's the patentable element then?

The provision of "security" by restricting of copying because of the patent seem to be a circular argument that doesn't justify the patent ;-(

Since starting this I have checked with the company who are authorised to make copies and their website tells me that they require a letter of authorisation to prove that I am entitled to ask for a copy.

It doesn't say how I find out who is the authorised person that provides the letter (nor how they keep their records up-to-date when that person changes - which in this case of this property it almost certainly has, not necessarily to someone who knows that they have this responsibility)

Which is fine for a small number of offices but as the number of codes goes up the chance of randomly guessing a correct code goes down.

With a six digit code, you have a million possible choices. Even if there are 100 flats, it is going to take a lot of random guesses to find one code. Then you need to find which of the 100 flats that opens.

The flats I have worked on have a remote fob and a keypad for the main gates (if applicable) and the for the communal doors. The actual door to each flat has a "normal" key.
