If you are always on the go, the Do-It mini 3-button remote control is a miniature version of Di-It's 3-button remote control, and just as powerful.

It can fit almost anywhere - in your purse, your pocket or 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 five-year 3-volt battery is included.
