Black and Decker garage opener not working, changed batteries and still not opening garage. How do you code a Chamberlain Universal Remote Control? What are the steps?

Do you have the Chamberlain 248735S garage door opener? Chamberlain doesn't have a 2487355 garage door opener; there are the 248735 and 248735S openers.

Most of the Chamberlain remotes are simple to open. Use the visor clip or a flat blade screwdriver to pry the two parts of the remote housing apart. There should be an open space on one edge of the short sides of the remote where you can insert the blade to begin separating the remote housing. Once started, you may be able to separate the rest of the housing by pulling the two sections apart with your hands. See page 32 of the user manual to see a picture of the separated remote or http://support.chamberlain.com/articles/How_To/How-do-I-remove-and-replace-the-battery-in-my-remote-control-1484145519292/?q=change+battery+in+remote&l=en_US&c=Brand%3AChamberlain&fs=Search&pn=1 for the procedure. Replace the battery with a 2032 coin cell battery, if you have the 248735S. Replace the battery with the correct replacement coin cell battery for other garage door opener models. Make sure that the side of the battery with the + faces the section of the remote housing with the buttons. The manual for the 248735S is currently here: https://www.chamberlain.com/CatalogResourcesV3/en-us/shared/files/tucmanuals/114A4256.pdf . Support and manuals for other models of Chamberlain garage door openers can be found from their support page: https://www.chamberlain.com/parts-and-support .

I hope this helps.

Call Chamberlain and ask if the handheld opener is compatible with older syster

If the wall control opens the door but all the remote units have quit then your logic board has failed.

Sounds like a faulty receiver or interference on the same radio frequency, try turning off any other wireless devices nearby to isolate the possible source of interference. If this does not work it might be worth fitting a universal remote control on a different radio frequency universal garage remote control

WHEN YOU CHANGE THE BATTERY NO NEED TO REPROGRAM THE REMOTE.
THE FLASHING LIGHT TELLS YOU IT IS SENDING A SIGNAL THAT IS BEING RECIEVED IT IS JUST NOT THE CORRECT CODE TO OPEN THE DOOR.
REPROGRAMING THE REMOTE SHOULD SOLVE THE PROBLEM

HOPE THIS HELPS

Posting your garage door model would help, but there may be a button close to the LED on the garage door opener that you have to depress to allow the two to pair up. Assuming that this is the similiar to my garage door control mechanism, if you have the dip switches set correctly you need to depress the button mentioned above and then depress one of the buttons on the remote.

first step can you change codes in one of the openers, or try the smart button of one

Does it work from wall button? Hit learn button for 10 seconds. Hit again for 1 second and code keypad.Opener lights should blink 2x. Hit learn again for a second and hit button on a remote (Any button you chose). Again, lights should blink. Now should work. Repeat for any other remotes.

THE NEW REMOTE MAY NOT BE THE CORRECT SYSTEM FOR THE UNIT YOU HAVE.
THE ONE THAT DOESN'T WORK MOST LIKELY NEEDS A NEW BATTERY.
NOTE IT MUST BE REPROGRAMED AFTER CHANGING THE BATTERY

HOPE THIS HELPS
