    Configuring garage door opener - LED doesn't flash rapidly

    I first cleared any previous programming by pressing and holding the two outer buttons. I then simultaneously pressed button 1 along with the button from the craftsman garage door opener keeping the remote once a few inches away and once as close as possible to the mirror.

    The LED flashes but it never does so rapidly to indicate the programming is successful. I have the same issue with the other two buttons as well.

    Any thoughts are really appreciated.

    I've had the same problem with mine.. but I got the door that I wanted coded so I quit.

    I was thinking that maybe that particular garage door has too many other devices attached to it that it can't handle all of them.

    Surprisingly, I had trouble finding concise instructions in one spot for programming the BMW Homelink Garage Door Opener (GDO) in my 2002 BMW E39 so I re-wrote what I found out here as a GDO DIY.

    Programming information can be found in this generic Homelink video.

    BATTERY:
    'They say" it is best to have a strong battery in the remote before you program your Homelink transmitter in your BMW overhead. The reason 'they say' this is because it's a recording; weak signal in === weak signals out ('they say'). Anyone with proof ... or logic ... please advise.

    RESET PROGRAMMING MODE:
    You do not need to reset but you might wish to erase all buttons when you obtain the car or sell the car.

    To reset all three Homelink buttons at once:
    1. Set the ignition with your key to the ACC2 position (no need to start the engine).
    2. Simultaneously press and hold the two outside buttons (#1 and #3) of your Homelink control unit
    3. Keep holding both outside buttons until the Homelink LED flashes rapidly (this will take about 20 seconds).
    That's it; the old settings are now wiped out for all three buttons.
    Note: Do not repeat this step unless you wish to wipe out all existing settings!).

    RE-PROGRAM PROGRAMMING MODE:
    0. You can program the Homelink after a reset or you must put the Homelink into "programming mode".

    1. To put the Homelink buttons into programming mode, press the desired button that you would like to reprogram and keep it pressed until the LED starts to flash slowly.

    2. Let the LED flash slowly for about 20 seconds.

    3. Only then (after the LED flashes slowly for about 20 seconds) should you release the button.

    The Homelink system is now in programming mode.

    Note: You will have five minutes to carry out the re-programming.

    PROGRAMMING FOR STANDARD CODES:
    This first procedure assumes a fixed code GDO (not rolling codes - instructions for which will come later).

    0. Position your hand-held remote transmitter 1 to 3 inches away from the HomeLink surface (located on your overhead sunroof panel), keeping the HomeLink indicator light in view (the closer the better in most cases).

    1. Using both hands, simultaneously press and hold both the desired HomeLink button (e.g., button #1) and the hand held remote's transmitter button.

    2. DO NOT release both buttons until the HomeLink indicator light flashes slowly and then rapidly.

    3. When the Homelink indicator light flashes rapidly, both buttons may be released.

    That's it (if you have a simple GDO); the rapid flashing indicates successful training of Homelink.

    Note: Apparently "Canadian Instructions" are slightly different; go figure.

    HOW TO TELL IF YOU HAVE ROLLING CODES: (i.e., encrypted codes)
    1. Press and hold the now-trained HomeLink button and observe the indicator light.

    a) If the Homelink indicator light is solid and continuous, training is complete and your garage door should activate when the HomeLink button is momentarily pressed and released.

    b) If the indicator light blinks rapidly for 2 seconds and then turns to a solid and continuous light, proceed with the following training instructions for a rolling code device.

    Note: A second person may make the following steps quicker and easier. Please use a ladder or other device. The Homelink people warn "Do not stand on your vehicle to perform the next steps" (duh).

    PROGRAMMING FOR ROLLING CODES:
    0. Apparently, you have to do the non-rolling code stuff above first; then, if you find you have rolling codes (based on the indicator light action described in 1b avove), then proceed as described below ...

    1. At the garage door opener receiver (aka, at the motorhead unit) in the garage, locate the "learn" or "smart" button (usually near where the hanging antenna wire is attached to the unit). If there is difficulty locating the training button, reference the garage door opener's manual or contact Homelink at +1-800-355-3515 .

    2. Press and release the "learn" or "smart" button (the name and color of the button may vary by manufacturer but a black button with a red LED is common).

    NOTE: Once the button is pressed, you generally have about 30 seconds in which to initiate the next step.

    3. Return to the BMW and firmly press and hold the previously trained HomeLink button for three seconds & then release.

    4. Do step 3 again (they actually told me to do this when I called for help).

    5. Do step 3 yet another time (just to be sure).

    6. HomeLink should now activate your garage door with rolling codes.

    Note: You can re-program any button at any time. If this procedure fails, you can call Homelink at 1-800-355-3515 for help (which is what I did and where additional steps above were added and a lot of my description was improved).

    PLACEMENT:
    1. To train, some remotes must be placed directly in front of the transmitter.

    2. Others at a distance of up to 30 centimeters

    3. In my case, I placed the remote transmitter right next to the BMW Homelink roof panel, actually touching the panel (that's what the Homelink Customer Support guy said to do - and it worked).

    Note: Make sure your battery in the remote is good. This may be an old wives' tale but 'they say' it's like a tape recording'; low-volume in, low-volume out.

    TESTING:
    1. Press the Homelink button you have now programmed.

    2. If the LED is constantly lit, you have successfully concluded the programming.

    3. You also should see the garage door opening (duh).

    Here are some more details on programming and troubleshooting the Homelink system on the BMW:

    RANGE PROBLEMS:
    Poor range can be caused by interference around or near the vehicle or due to the use of older batteries in the original transmitter during programming.
    Put a new battery in your hand-held transmitter. Training the HomeLink takes more power from the battery than when you push the button to open the door. Sometimes by putting a new battery in the hand-held transmitter, it does help pick up a better train and increases the range.
    Retrain the HomeLink at different lengths and angles. Start by holding the hand-held transmitter 3-4 inches away then 5-6, even 6-8 inches from the buttons. Sometimes this helps pick up a better train to HomeLink.
    Try a second transmitter with new batteries.
    Straighten the antenna wire that hangs down from the garage door opener motorhead.
    FREQUENCY:
    HomeLink is an integrated transceiver (a transmitter and receiver) that can be programmed to activate radio frequency (RF) devices such as garage doors, estate/community gates, entry door locks, home/office lighting, or other RF devices.

    HomeLink is compatible with radio-frequency devices operating between 288 and 399 MHz (exclusive of the restricted 322-335 MHz range). Select 2007 and newer vehicles are compatible up to 433 MHz (exclusive of the restricted 400-410 MHz range).

    COMPATIBILITY:
    Please contact us by email or phone ( 1-800-355-3515 ) to verify vehicle compatibility.

    TROUBLESHOOTING:
    You can either call our customer service number ( 1-800-355-3515 ) or contact us by email for complete programming assistance. First try the following troubleshooting tips:
    Check the frequency of the device's hand-held transmitter (usually found on the back). HomeLink is compatible with radio-frequency devices operating between 288-399MHz (some 2007 and newer vehicles may be compatible up to 433MHz. Please contact us for vehicle compatibility).
    Put a brand new, store bought battery in the hand-held transmitter. During the programming process the battery's energy tends to drain (more so with an older battery). A new battery will increase the speed and accuracy in which the hand-held transmitter sends its signal to HomeLink.
    Retrain HomeLink holding the hand-held transmitter at different lengths and angles from the HomeLink button you are trying to program. Try 4-6 inches away at a different angle.
    Cycle the hand-held transmitter during programming: Press and hold the HomeLink button while you press and release the hand-held transmitter every 2 seconds until the indicator light changes from a slow blink to a rapid flash.
    To verify HomeLink has programmed, press and hold the HomeLink button and observe the indicator light:
    If the indicator light remains solid, it has picked up the signal and should operate the device.
    If the indicator light blinks rapidly for two seconds and turns solid, HomeLink has successfully picked up the rolling code signal. Please follow the rolling code instructions outlined in the "programming a garage door opener" section to complete the process.
    If the indicator light remains a slow blink, HomeLink has not picked up the signal from the hand-held remote. Try programming the button again or choose another button to program.
    PROGRAMMING FOR A PRE-1982 GARAGE DOOR:
    As long as the garage door opener is in the same frequency band (288-433 MHz*), HomeLink can be programmed to this older unit. However, frequencies of some older openers can shift outside of the HomeLink operating band, and become incompatible. The best way to program an older garage door opener is:

    1) Put NEW batteries in the original transmitter and
    2) Hold the original transmitter between one and three inches away from the HomeLink surface until HomeLink learns the signal (refer to our programming section for complete instructions).

    If HomeLink has not picked up the signal within a few seconds, position the original transmitter at different lengths and angles.

    If these suggestions do not work, you may have a problem with the garage door opener itself. If you chose to contact a garage door opener service technician, be aware that, under FCC regulations, they or anyone else are unable to service the device if it was manufactured before 1982. Many garage door openers manufactured before 1982 do not have the safety stop-and-reverse feature which is now required by law. Some states (NY, IN, CA, MN) require service technicians to totally disable the opener if they find it to be malfunctioning.

    WHAT IF I DON'T HAVE A HAND-HELD REMOTE GDO?
    You have to have a hand-held transmitter to program HomeLink.

    KEELOQ-based Rolling Code Garage Door Openers:
    The HomeLink unit uses Microchip's KEELOQ rolling code technology to access some brands of garage door openers. Every KEELOQ-based HomeLink transmission includes 5 parts:
    Serial Number
    Button/Function Code
    Status Code
    Counter Value
    Discrimination Bits
    In a given message to be transmitted, these portions are organized as follows:********>********>*******>********>******* >********> *******> ********>
    Unencrypted Encrypted
    Status
    Code
    Button
    Code
    Serial
    Number
    Button
    Code
    Discrimination
    Bits
    Counter
    Value
    The HomeLink unit transmits an unencrypted portion and an encrypted portion. The message is transmitted starting with the bit furthest to the right in the above figure and ending with the first bit furthest to the left.

    Unencrypted Portion of the Transmission
    The unencrypted portion of the transmission includes the status code, the button code, and the serial number.

    Serial Number (24 or 28 bits).
    Each HomeLink unit has a serial number which the garage door opener reads to distinguish the HomeLink unit from other HomeLink units or other transmitters. The serial number can be 24 or 28 bits long, depending on the garage door opener system, and the lower 8 bits are used to form the discrimination bits. The serial number is loaded from memory for each transmission.

    If all else fails, call Homelink at 1-800-355-3515 for help - and write back here what you found out.

    This was very confusing, but is KEY to making it work!

    You must do the first part of the programming (non rolling code steps) and then do the rolling code setup.

    Thanks bluebee & Martin for this write up!

    The right BMW Homelink instructions

    below are instructions from the previous post,,with the correct modifications in bold,,

    RESET PROGRAMMING MODE:
    You do not need to reset but you might wish to erase all buttons when you obtain the car or sell the car.
    To reset all three Homelink buttons at once:
    1. Set the ignition with your key to the ACC2 position (no need to start the engine).
    note: the ignition switch must be either in acc/2 position or engine running position for the Homelink to operate.
    2. Simultaneously press and hold the two outside buttons (#1 and #3) of your Homelink control unit
    3. Keep holding both outside buttons until the Homelink LED flashes rapidly (this will take about 20 seconds).
    The error here is that you must keep holding the two outside buttons down when the light is flashing rapidly , until the light stops flashing and goes out completely ! Now the unit is clear of old programming and ready for new programming,,, !
    That's it; the old settings are now wiped out for all three buttons.
    Note: Do not repeat this step unless you wish to wipe out all existing settings!).
    RE-PROGRAM PROGRAMMING MODE:
    0. You can program the Homelink after a reset or you must put the Homelink into "programming mode".
    1. To put the Homelink buttons into programming mode, press the desired button that you would like to reprogram and keep it pressed until the LED starts to flash slowly.
    error: when you press and hold the desired button the light starts out as a solid light (no flashing) then as you continue to press and hold the desired button it changes to a slow flashing light.
    Without releasing the desired button, (while it is flashing slowly) press and hold the garage door remote key and hold it until the Homelink light flashes rapidly, now you are really done ! It works !

    the entire rest of the previously posted instructions are no good if you want to open your garage door from your BMW and not even Homelink got this right ! I will send them the proper instructions,, I have not done any engineering on the roaming code operation,,, yet,,

    I've been trying to get this working in our 2013 X1 since early October with 0 success. I've called BMW and I've called Homelink with no success. It's really one of the, if not the most frustrating thing I've ever dealt with in a vehicle. I tried 3 other cars, Lexus, Ford, Hyundai all programmed with no issues in less than a minute.

    I can't even get the first step to work in the X1. The Homelink light never goes from a slow blink to a fast blink when I have the remote close to the buttons. I've read hundreds of posts and tried everything. Why can't BMW get this right like every other car manufacturer?

    If you are having that much of an issue with it, then I would buy a used on ebay. I got one a few months ago for about $45. If not, then I would see if a neighbor/friend would let you try on their door.

    Buy a used what on eBay?
    I've seen a few people said they purchased a cheap keychain remote, sync that to the opener and then sync that to the Homelink.

    Sorry, you are in the e46 section. I skipped over the part where you said 2013 X1. e46's have the module up by the sunroof switch that can be bought on ebay for around $45.

    As for your situation, I would try holding the remote in different locations next to the mirror/ module. One guy had to touch the mirror to get it to work in his e90.

    Without releasing the desired button, (while it is flashing slowly) press and hold the garage door remote key (Hold to the left side of the mirror right next to the button) and hold it until the Homelink light flashes rapidly, now you are really done ! It works !

    the entire rest of the previously posted instructions are no good if you want to open your garage door from your BMW and not even Homelink got this right ! I will send them the proper instructions

    Roaming Code Instructions:
    • On the back of your garage door opener press a button until it blinks (auto-sensing)
    • You have 30 seconds to run to your car and press same button you just programmed three times
    • GARAGE DOOR WILL Close or Open

    Thank you for your previous instructions .. took me forever to get this working !!!

    I got a 2012 335i for my son a high schooler, and it took me forever to make the Homelink to work.

    Here is what I did: basically the combination of different steps (posted by dpmaui and bezerker77------------THANK YOU!!!).

    Reset programming mode
    1. Start the engine.
    2. Simultaneously press and hold the two outside buttons (#1 and #3) of your Homelink control unit.
    3. Keep holding both outside buttons until the Homelink LED flashes rapidly, until the light stops flashing and goes out completely !

    Put the Homelink buttons into programming mode
    4. This next step is what I did differently to make my Homelink to work: press the desired button (such as #1) that you would like to reprogram, the Homelink light starts out as a solid light (no flashing) and keep it pressed until the LED starts to flash slowly, then keep pressing the bottom until the light stops flashing and goes out completely (similar to step 3).

    Action mode
    5. Then, press and hold the desired button (such as #1) again, the light starts out as a solid light (no flashing), then as you continue to press and hold the desired button it changes to a slow flashing light. Without releasing the desired button (while it is flashing slowly) press and hold the garage door remote key (hold to the left side of the mirror right next to the button) and hold it until the Homelink light flashes rapidly (finally!!!!!!!!!!!!!!!!!!).


    6. Press the auto-sensing button of the garage opener (it then blinks), run back to the car, press the desired bottom (such as #1) three times (about two seconds each time), BINGO!

    I almost gave up, but I am glad I finally make it work. Thanks to dpmaui and bezerker77!!!
