All of the flats have a box like this one outside the front door. This one, outside my door is newer than most and I assume was installed by the former owner of the flat.

The purpose being that a carer can open it up to get a key so they can let themselves into the flat to help their client. It saves having to give out keys to carers / workmen, etc.

I don’t have the code for mine. I reached out to the Estate Agent (Realtor) asking him to get it from the former owner’s son. The son didn’t know the code. Makes me wonder how much the former owner trusted her son.

As I don’t know the code, I’ve begun the long winded process of cracking the code by starting from 0 and trying a few numbers every time I’m in the mood to give it a go. It’s a good job that I don’t need to use it as it’s going to take a long time to get to it.

Any of you burglars have any ides on how I can crack it quicker?
