I can not get the car button programmed to the 971LM Professional. I press the orange button, jump into my car and hold down the remote button and my car button. The light on the opener flashed once but the car button doesn't engage the garage door.

    I just put in 2 new Chamberlain Model 995XDM garage openers. I cannot seem to get either car's universal remote to activate them using either static or the rolling code programming procedures. The cars are 2004 Chrysler Concorde and 2001 Chrysler 300M. Both have the 3 button remote built in. I've tried the 'learn' button on the opener and then holding one of the cars buttons to no avail. My question is do these openers even have the ability to be programmed to these car's built in remotes or am I just not doing some correctly? Many thanks.

All the cars are different check to make sure you don't use your remote to program your car button. Some cars are set up like this. You must hit the button in the car within 30 sec. from pushing the button on the back of the operator.

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.

Programming time warner remote to boston tvee volume


I had just about given up on programming my Time Warner universal remote with my Boston Soundbar until a mental lightbulb came on. This is a two step process. Step 1: Program your Time Warner remote (I have CLIKR-5, instructions available for other models at timewarner.com) Using Pre-Programmed 3-digit Code method -Turn on soundbar - Press device button (I chose AUX) and OK/Select simultaneously until device button stays lit. - Point remote control toward the soundbar and enter code (447 for Boston Acoustics) - Press the device button again to store the code. The TW instructions say you should now be able to turn the device off to verify that it works, but this is not true for the soundbar. Hang in there with me. Step 2: Program your remote from the Boston Soundbar. - Press the power button and the volume up button simultaneously until the indicator light flashes orange. Here's where the instructions provided with the soundbar fail to explain how to do this. Each button is individually programmed into the TW remote. What you have done so far is enable the remote to accept the programming. - Volume Up: press the volume up button on the soundbar while it is flashing, the light should become steadily orange. - While holding the remote steady about a foot away from the soundbar, slowly press the volume up button on the TW remote four times. The orange light should flicker each time you do, turning green when completed. - Volume Down, Mute, Power: repeat the steps for Volume Up, except press the button on the soundbar you wish program to the TW remote while the soundbar is flashing orange. It should become steady before you press the corresponding button on the TW remote. Good luck, I hope this helps. -Deidre.

I am trying to reset and synch a 971LM remote.


To program the remote do this:

Press and hold the button on the remote while you press and immediately release the smart/learn button. Should be programmed if all is working. The smart/learn button is on the rear of the motor unit near where all those white wires go.

I just purchased Liftmaster 971LM for my 139.53975srt1 Sears 1/2hp garage door opener. It will not program. I have only one working remote that was recycled from my father's unit - it says craftsman...


If the recycled remote is Security + there is no logical reason the new units should not work. If the old remote is a different technology and there have been changes to the opener or a different receiver that could be the problem.

Remotes won't program! Installed Viper 5001 on my 2007 Kia Sorento. Triple checked wiring..all is good. Remotes won't program...no power to main unit. Yet, tested main unit and it has power. Any...


There are two constant 12 volt wires at the ignition on this vehicle: blue and green. The red power (with fuses) wires from the Viper should be connected to either of the two. The ignition wire is yellow. The pink wire from the Viper should be connected there. The accessories are orange and white. The pink with white from the Viper should connected to one and the orange from the Viper should be connected to the other. Please note that the Pink with white should be programmed to act as an accessory (off during crank). The starter wire is red and the purple from the Viper should be connected there. Also check for a good ground connection.

For programming:
Press and hold "f" until LED lights solid (approximately 10 seconds), then press and hold remote starter button(circle w/arrow) until LED blinks three times and the amber transmit LED lights up.
Now you have to enter the remote control learn routine: Turn ignition on, within ten seconds press and release control button on antenna then, press and hold control button while pressing the lock button on remote. System will respond (horn/chirp/flashing parking lights) when holding control button and when pressing lock button on remote.

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.

Pres remote starter Model APS-901, the remote will start the vehicle but then it immediately shuts off


PLEASE READ THE ENTIRE POST BEFORE BEGINNING

There are several reasons that could cause the remote starter to shutdown immediately after it starts:

1. It may be the lack of a tachometer signal. Did you hook up the green/orange wire to a uncommon wire at a coil or fuel injector? If not, did you program the remote starter for tachless? If you didn't hook up the tach wire, no problem; let's program the remote starter for tachless:
Turn ignition on, press and release programming switch three times. The parking lights will flash one time. Turn key off, then on, then off, then on. You are now in bank three (remote starter programming). Press and release the programming button five times. The parking lights will flash the number of the times for the setting for this feature. If you have not attempted to progarm the unit, it will flash two times (default setting is for TACH). Press and release the start button on the remote once, it will flash three times; press and release the start button again, it will flash once. The unit is now programmed for voltage. Turn the key off. If you have not attempted to do any programming on the unit, the default setting for crank averaging is AVERAGING. This means that you will have to start the vehicle at least four times with the key to be effective. Test the system.

If the problem still exists, let's try this:
2. If you did not hook up the tach wire and you already had the unit programmed for voltage and, the remote starter shuts down (probably when the parking lights come on); the 901 is seeing a drop in voltage and you need to hook up the tach wire. Connect the green/orange wire to an uncommon wire at a fuel injector or coil. An uncommon wire is one that is a different color, at the same pin location, on each coil or injector. For example; compare two fuel injectors: if they are two pin connectors you may see an orange and a pink. At the next injector you may see an orange and a blue. The orange is the common wire and the pink and the blue are uncommon wires. You may connect the green/orange to either one of the uncommon wires. After the wire is connected, turn the ignition on, press and release the programming button three times. The parking kights flash once. Turn the key off. Press and HOLD the programming button, start the vehicle. The parking lights will begin to flash, continue to hold programming button for approximately 15 second. Release the programming button, the parking lights will come on then, go off. The tach is now programmed. Turn vehicle off. Refer to the above section for remote starter programming features in bank three. Test system.
Remember: If you did hook up the tach wire there is no need to program the 901 for tach. Tach is the default setting.

3. If the remote starter still continues to shut down, the problem may be with your need for an immobilizer bypass. You failed to mention the year/make/model of the vehicle so, try inserting the key into the ignition then, remote start the vehicle. If the vehicle starts and runs, you will need to bypass the "chip" in the key for the remote starter to function as desired.

Liftmaster 971LM opens but won't close correctly


Check the wiring going to the sensors to make sure it is not broken or disconnected. You have a problem with the sensors themselves or the logic board. Unfortunately the only way to be sure is to replace.

Sears Craftsman Garage Door Opener Wireless Keypad Model and a LiftMaster Chamberlain Professional Garage Door


Hello,

I had the same frustrating dilemma with my Craftsman LiftMaster garage door and Keypad, Model 139.53754-01 (dated 10/06; and has the # 315 MHz).

To resolve “the dilemma”, grab your keypad, climb up on a ladder to access the garage door opener’s motor unit. On the right side of the motor unit, remove the white plastic casing by pressing buttons on each side and pulling down. This will expose the programming area, and for our purposes, the “Learn” button.

1. On the motor unit, press and release the “Learn” button. The Learn indicator light will glow steadily for 30 seconds.

2. Within 30 seconds, enter a four digit personal identification number (PIN) of your choice on the keypad. Then press and hold the ENTER button.

3. Release the ENTER button when the motor unit lights blink. The code has been “learned”/stored/activated.

Good Luck, and I Hope this Helps!
Gail
For possible future reference:

How to change an existing, known PIN
(Changing an existing PIN can be done with the wireless remote keypad, and does not require access of the motor unit.)

From the keypad:

1. Enter the four digits of the present PIN, then press and hold the # button. The opener light will blink twice. Release the # button.

2. Enter your new 4-digit PIN and press Enter. The motor unit lights will blink once when the PIN has been “learned”/stored/activated. Test by entering the new PIN, and pressing Enter.
