Why will my garage door opener not open with remote?

If the garage door opener worked ok the last time you used it, maybe the battery inside the remote has just gone flat and needs to be replaced? <><><> Also, make sure the two are compatible. If either one is new, you have to make sure they code the same (dip switch or rolling) and that they transmit on the same frequency. If they are not compatible, think about replacing the remote as changing the opener is much harder. Just figure out the two things mentioned earlier for your opener and find a remote that matches those. For further advice see web sites such as the Related Link below.
