CodeDodger Access Security System is a digital coding system used by Overhead Door garage door openers to prevent someone from "grabbing" a radio signal that openers your door.

• Prevents illegal entry from remote controller access code signal duplication.
• Eliminates need to set security code when opener is installed.  Each remote controller comes with its own continually changing access code.
• Automatically changes access code each time remote controller is activated.  Each new code is selected from 4.3 billion combinations.
• Prohibits opener from responding to the same access code more than once.
• Recognizes access codes from up to seven remote controllers used to operate the same openers.
