Fermax opens doors

The Fermax Memokey System City 100 Codes is a door opener with a keypad. When we renovated the house, I wanted a system like this so we could grant/revoke access to people (babysitters, cleaning lady) without handing out keys. As an additional benefit, when you lock yourself out without a key, you still can get access. After installation, the electrician explained the system and handed over the documentation. All things set, this worked as it should for 3 months and then this thing happened with halloween. Someone rang at the door while I was changing the diapers of the baby. So nobody answers the door. Suddenly, I hear kids singing in the hallway! Nobody could have opened the door because I was upstairs. So how did they enter? I rushed downstairs and asked how they managed to open the door. One of the kids explained that his older brother followed a course as an electrician and they are trained on these type of access systems. His brother told him that these systems come with factory default codes like "1111". So he tried one of the default codes and entered and started singing with his friends. Imagine my surprise. After reading the documentation, I managed to reset the system and remove the factory defaults. Now, what can we learn from this? Fermax forgets that electricians are busy people and sometimes forget to reset factory defaults creating a potential security risk. Not a good thing for a company selling security related products! Unfortunately, this happens too often. For convenience, manufacturers ship their products with default codes that stay active after installation.
