With automobile manufacturers building code copiers directly into todays cars, it's easy for a supposedly "secure" RF transmitter code to get into the wrong hands. This can't happen with MicroPLUS RF controls. MicroPLUS RF controls provide you with the highest level of security available with RF access controls. Our coding and encryption schemes are not shared with other producers, resulting in transmitter codes that cannot be duplicated or copied. With MicroPLUS controls, you are assured that only the original intended transmitter will activate your access system.
