Many homes have been broken into and burglarized by thieves using universal controls that open the garage door by reading the access code in the opener. Rolling access code technology is one way to protect your home, family and belongings against thieves and intruders. Rolling access code technology changes the code of your automatic opener after every use, so the thieves' universal controls are rendered useless. All new residential garage door systems which we have installed in the Chicago, IL area have been rolling code since 1997. If you have a Lift-Master or other Chamberlain made opener it is rolling code if you have "Security+" designated on the system (or remotes). For Genie / Overhead brand units if it says "Intellicode" it is rolling code.
Although it is possible to purchase a universal receiver and transmitter retrofit kit to make your system rolling code it is usually better to invest in a new garage door opening system due to the age of the non-rolling code systems (usually over 12 years old).
