Check to make shure the battery from the second unit is good because it was stored for a period of time ,make shure it,s installed correctly . and after installing battery press any of the buttons you should see the keyboard light up , if you have a hard time seeing it because of the daylight just cup your hand,s around the display ! If that is all good then before installing the keypad on the outside jam ,go to the machine and locate the srt button or the smart button , after you located it just press it once and the yellow indicator light will turn solid , at this time you can program 4 digits into the keypad and hit the enter button on the keypad , At this point after pressing and holding the enter button ,you will see the machines lightbulb turn on and off once , that is telling you that the machine has just accepted the code ,for your other machine do not use the same code because the two doors will open togeter for example 1234 enter.................2nd machine 1235 enter you should have no problem programming the machines , theese are the easiest machines to programm and only take litteraly a few swconds each ....it takes me less then 5 seconds to do each ! also another way to check if your keypad is sending a signal back to the machine is find the srt button or the smart button (,they are the same button) look at the yellow indicator light next to it and then press the enter button and hold it down on the keypad you will see the light on the machine blinking rapidly , That is telling you that the machine is recieving a signal ! Good luck and hope this helps you , if your keypad still don,t work bring it back to sears for a replacement , sincerely Glenn

Transmitter Programming
Important: Up to 4 transmitters can be programmed. Do not operate or program the transmitters in the vicinity of other vehicles that are in the keyless entry program mode. This prevents the programming of the transmitters to the incorrect vehicle. The order in which the transmitters are programmed is important. The first transmitter programmed will be transmitter #1, and the second transmitter programmed will be transmitter #2. Use care to program the transmitters correctly.
The scan tool must stay connected until all of the transmitters are programmed.

Why Can't I add another remote to a merlin mt60p


If you purchase additional transmitters, the garage door
opener must be programmed to accept the new remote
code.
Program the Receiver to Match Additional Transmitter
Codes:
Using the orange "LEARN" Button:
1. Press and hold down the transmitter button you wish to
program to the opener. The orange LED will flash to
indiciate it is receiving signal from the transmitter.
2. Press and release the "LRN" button.
3. The sourtesy LEDs will flash once.
Ensure the door is clear of obstruction, then test the
transmitter.
Using the Motion Detecting Control Panel
(optional accessory):
1. Press and hold the button on the hand-held remote that
you wish to operate your garage door (1).
2. While holding the remote button, press and hold the
LIGHT button on the Motion Detecting Control Panel (2).
3. Continue holding both buttons while you press the push
bar on the Motion Detecting Control Panel (all three
buttons are held) (3).
4. Release buttons when the opener light flashes. It has
learned the code. If the light bulb is not installed, two
clicks will be heard (4).
Now the opener will operate when the transmitter push
button is pressed. If you release the transmitter push button
before the opener light flashes, the opener has not learned
the code.
To Erase all Transmitter Codes:
To deactivate any unwanted remote, first erase all codes:
Press and hold the orange "learn" button on opener until
the learn indicator light goes out (approximately 6 seconds).
All previous codes are now erased. Reprogram each remote or keyless entry you wish to learn.

Seems you've done everything right. Press and immediately release the smart/learn button and then walk over and key in a 4 digit code and press enter. If you are sure the battery in the keypad is good then I think your keypad is on the fritz or the wrong one for that opener.

Moved to a place with a 139.53975SRT1 Garage Door and Keyless Entry. Keyless entry stopped working and I cant get code to operate door. All remotes stopped working. Reset codes with Learn button,...


Try this method for programming. Press and hold the button down on the remote while you press and immediately release the learn button. Do this for each remote.

Have you replaced the battery in the keypad? Try this:

Locate the smart/learn button on the rear of the motor unit near where all those white wires go. Press and immediately release this and then walk over to the keypad and key in any 4 digit code you like and press enter.

Post back with your results.

Opener will not recieve programing instructions from the keypad.


There should be a button on the back of the door opener that says "teach" or "learn". Push that button, a light comes on and you have about 30 seconds to program the control by holding it near the unit and holding the remote button down. The opener will then learn the code from the remote.

Wireless key pad and remote openers for the cars work intermittently have tried re-learning


Your remotes and your keypad are small transmitters that send a signal to the receiver. If all your units are intermittent then it is the receiver that is bad. The receiver is part of the logic board.
