Will home invaders be able to enter my home through the electronic PlexiDor? The PlexiDor Electronic is difficult to force open and not a likely point of entry for potential burglars. It would be easier to break a window. The door only responds to certain RFID codes, and in order to be reprogrammed to open for another key, a person has to already be inside the house, remove the cover, and access the circuit board. When it comes to breaking through, the door has an interior stainless steel locking bar and the panel is shatter resistant. If someone were to kick the panel – or hit it – they would bounce off. The frame is made from sturdy aluminum. The manual PlexiDors come with a lock and key and a steel security plate that screws onto the frame.
