I have a Stanley garage door opener model 8500. I replaced the door and now my operate button doesn't work. Is there a reset?

My best advise to you is get the brand name remote for your opener. I know it sounds like a pain but click brands are not super great because there supposed to work for many different kinda. For the most part you can call your local garage door dealer and pick one up for your opener. They may sell you a lift master brand opener which is find sears/liftmaster/chamberlain are all the same. Should only be about 35 bucks if you pick it up

This web address came from the Chamberlain site. I also needed to relearn my remotes due to a newer car that has a built in garage door opener that needed to be set. I also needed to reset my keypad remote, those instructions I was able to get from the same site. Good Luck

I just found the solution for my 'ancient' Sears garage door opener, model # 139.655000, and I figured I'd share it.

There's a separate radio module, wired to the main opener. This module is small, has a short wire/antenna, and plugs directly into an outlet.

There's a manual open/close button on this module (I didn't realize this until I got up on a ladder). This button is also a removable cover; underneath it is a "smart actuate" button -- this is your learn button.

What I did was: unplug the radio module. Pry off the cover. Plug the radio module back in. Hold down the button on the remote. Press the "smart actuate" button. This programmed my remote successfully!

This is the most complicated way I know of coding a remote and I am a tech. who does this all the time.
Turn power off. Wait 3 sec's & turn back on. Quickly press program button on back of box twice. Lights will flash, bottom light will stay on. Press program button twice, & No. 3 light will start flashing. Press and hold your remote button until light stops flashing. Code will be accepted.
