Are you always on the go? Our mini 3-button remote control is a miniature version of our 3-button remote control, and just as powerful. It can open and close 3 garage doors or gates, turn opener lights on/off, and/or turn on lights and small appliances in your home. And the best part is that it can fit almost anywhere – in your purse, your pocket, or even on your keychain. It features Security+® rolling code technology that sends a brand new code every time it is used, keeping you, your family, and your belongings safe and secure. One 5-year 3-volt battery is included.
