Decoding a Push button key cabinet

Decoding and opening of a pushbutton key cabinet. This cabinet is sold to use with a spare key. Giving multiple users access to the key, without the need for giving them their own key copy. But it is not really good made, and the locking mechanism offers low security. So keep in mind the risk of unauthorized access when installing one like this. The cabinet used in this video is a "No-Name", but equal cabinets is sold under varies names. They all have the same security flaw as exploited in this video...
