Their customer service SUCKS (as does their product) but their toll free number is 1-800-521-5262 and their e-mail address is firstname.lastname@example.org. If I were you I would just go out and buy a REAL garage door opener. I have been waiting 33 days for someone from Innovative Home Products (the company that makes Stanley garage door openers) to call me back for warranty service on my garage door opener that is only 9 months old. They are probably hoping if they sit on their butts and don't return my calls, that I will go out and buy a new opener and then they won't have to honor the warranty ! Good Luck. . . I hope you get better service from them than I have gotten.
