When it comes to security, older garage door openers are considered to be more at risk to theft attempts, as opposed to newer models. This problem relates to the fact that older model remote controls can operate with a “fixed code”. There are now devices that can be used by thieves in order to “capture” these codes and use them to create their own remote. Modern remote controls operate by using random codes that they produce each and every time the control is used. Because of this, thieves are unable to duplicate the code needed to open your garage door.
