Older model Allstar garage door openers were originally equipped with varying types of radio receivers and remote controls most of which are no longer made. We recommend that you install a new radio receiver/transmitter. This radio gear features the new rolling code technology for added security. The one we recommend is our Universal Remote Control Kit (this includes the new receiver and one remote control).  It is quick and easy to install. Since it is an add-on receiver, you can continue to use any remote controls and keypads that are currently working with your garage door opener. You can add additional remote controls at any time and also a wireless keyless entry keypad if you desire.
