I CAN NOT PROGRAM MY BUILT IN CAR REMOTE ON MY NEW 139.53985DM

Stacy, get a ladder and climb up to the opener. The directions are there, but typically you press a button for x seconds, and then press a button on the remote. This handshakes the two units. continue for other remotes.

Push the learn button on the opener
an then hold the remote under the opener an hold the button on the remote till the lights flash on the opener you have about 10 sec. to do this

If you didn't, try programming the remote this way.

Press and hold the button on the remote and then press and immediately release the smart/learn button on the motor unit. If this doesn't work you need to make sure you have the correct remote for the model opener you have. Your model number doesn't bring any results from Sears Parts.com.

I don't trust batteries even when they are new. Try taking the battery out of the remote that is working and install it in the remote that isn't. If that doesn't work you need to purchase a new remote.

If your keypad is the same age as your door and worked before it has probably just quit. If it is new and you have programmed it and it still doesn't work it may be the wrong one for your model opener.

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

You have a remote or keypad that has reverted to an earlier technology. You need to eliminate the bad unit and the others will program. Sears is made by Chamberlain which also makes Liftmaster and several privately branded openers.

GOTO HOMELINK.COM

THEY MAKE THE SYSTEM AND HAVE INSTRUCTIONS YOU CAN DOWNLOAD.

PLEASE NOTE: NOT ALL BRANDS/MODELS OF OPENER WILL WORK WITH THIS SYSTEM.

HOPE THIS HELPS

sounds like you are doing keypad ok. is battery good. as far as homelink in car. follow directions for rolling code/security plus.

having all the remotes you want programed with you, find learn button on back of opener. hold button until little light goes out- no remote will work now, with each remote Press learn button once,Press big button on remote-light bulb on opener will blink on/off if bulb is working-do this each hand held-keyless is same way, put you 4 #'s in HOLD enter button-light bulb blinks on/off you have 15 sec. for each time you hit the learn button. also best to start off with new 9 volt battery before you start programing
