This is a brand new never been used key pad for outside garage door. Go for a walk and you don't need your keys. Would you like to be able to have a loved one come in and check on you? This is a great way for them to get in. This is for a garage door opener with a purple learn button. Also has a temporary learn code for workers that may need to get in your home.Tv guy, plumber etc. Just put in temporary code.
