You'd better hope that the local thugs don't carry a code grabber. Some of the newer system are encrypted or scrambled. Some thieves make the rounds clicking a code grabber as they stroll down the block hopeing that someones garage door will open. In the meantime, make sure your new garage door system default is changed out using your own personal ID.
Edit: I own pg. 2, hehe.

Dave, since you've already did this, does the Homelink unit lose it's programming if the 12v power is removed? Just curious.
John, your right about the 84's and a bunch of other GM cars, it seems to be pot luck sometimes on how a car is wired up, it varies from year to year. (In his best Forest Gump voice) It's like a box of chocolates............................................
I have mine wired permanently so I don't know for sure. I am pretty sure they have a memory chip or they would have to be reprogrammed every time you changed a battery or had a dead battery.

Well next time you work on the car and unplug the battery, let us know if the opener still works. I'm tempted to do this myself, and my mother could really use one since she can't find clickers for our door opener.
Here is some information from a Homelink webpage so you will not loose memory if you connect to a key powered wire for security.

This sounded like a great idea so I stated looking on Ebay to find a Cadillac module and noticed that the early model modules had a two wire connector but the later model modules, that are "rolling code" compatible, have a three wire connector. Since my garage door openers use the rolling code technology, that should be the Homelink module that I will need to use. My question is, what is the third wire used for ?

I tried the schematic route but all I could find were sites that would sell the information for "interesting" prices. I had a few minutes today, so I went by my favorite yard and got lucky. I found a 1998 STS with the controller installed. Ten dollars later it was mine, including the whole mounting plate and wiring. It turns out that the circuit board has three contacts but only the outside two are used. The plug has only two wires, is not jumpered internally and there is no other provision to power the center contact on the circuit board. I still don't know what the center contact was to be used for but it makes no difference. The rest of the project will come when time allows.

O.K., anybody having problems programming their unit...?
I've got an Overhead Door rolling-code garage door opener that is HomeLink compatible, and I'm following the directions that came with the module, that are on the HomeLink website, and in my garage door opener manual... even though I'm cycling the button on the handheld transmitter like the directions say I should (it only sends the signal for a couple of seconds each time), the light on the HomeLink module just keeps flashing slowly for about 30 seconds at a time then just stays off.
Anybody know what I'm doing wrong? Seems hard to screw up just holding down two buttons at the same time... how many seconds did it seem to take before the HomeLink module started flashing rapidly, indicating that it accepted the code? 2? 5? 10? 20?
If I am not mistaken, you have to hold the garage door transmitter close to the homelink and program that first. Then press the training button on the garage door motor and then click once more the homelink to activate the programming. Hope this helps.

Yes, programming the HomeLink module is what I'm talking about having problems with... if I could get the module programmed, I don't think I'll have any problem 'training' the garage door opener.
How long did your HomeLink module blink slowly until it blinked rapidly and accepted the code from the hand held transmitter unit?
From what you have dercribed, it seems like your transmitter is not sending the signal long enough for the homelink to capture. Just to be sure, are you pressing and holding down the button on your transmitter until the homelink starts flashing rapidly?

Yes, I'm holding the button, but the red light on my handheld transmitter doesn't stay on steady - it blinks.
According to the directions, if that's the case (that the signal isn't one long, constant 'beam'), then I am to re-press the button on the handheld remote every two seconds while holding the HomeLink button steadily the whole time.
I'm not sure what's not working...

Well, sh*t... I dug out a larger transmitter, one that continued transmitting (according to the light that stayed on the whole time that I held the button down), and the HomeLink module still just sat there and flashed slowly the entire time.
I noticed that Skitime's has a red light and mine has an amber (which was why I got it - figred it matched the interior lighting closer than true red) - does that make any sort of difference? Is that indicative of a different model? The auction I got it from stated that it was compatible with 'rolling code' garage door openers...
I'm beginning to feel like I got ripped off for $60 on the auction...
Don't worry. I don't think the light makes a difference. Another ? Did you clear the codes that were in the homelink module already? If you have not, that would explain why is not doing anything. So, put you garage transmitter aside and lets clear the codes. On your homelink, press and hold the first and third button until the light starts to blink fast. Once you see that, it means that the old codes have been erased. Now, try the procedure again. This should work.

I am having problems getting mine to take a code as well. I've cleared the codes, and tried at least a dozen times using the instructions from the homelink website. I think that the one that I got might be incompatible with the newer rolling code openers.
I am debating on getting another one from a newer 2005 or up car.

I just read that the openers with the amber light are rolling code compatible, and the one with the red light are not. I have the one with a red light. I am not sure I wnat to spend money on another one if it might not work.
Perhaps I will go junk yard shopping and might get lucky . They go pretty cheap in the local yards.

I just went to my vehiocle to check the light since I had never paid any attention to it. Mine is amber in color. I would suggest that you buy the same kind as the one mentioned in the thread. That is what I did and had no problems whatsoever. Good luck.

Tried it again today, after clearing the codes out (by holding the two outer buttons until it flashes), then using my larger handheld remote (which stays on steady as long as you hold the button) - still won't program. ARGH!!!
So who in this thread has red lights on theirs, and who in this thread has amber lights on their HomeLink? And what brand of grgare door opener? Is it a rolling code or not?
Who has been successful, and who has had problems?
Let's get together and see if we can figure the details out so nobody else gets screwed buying the wrong module for their setup...

O.K., I was just reading in my garage door opener manual to retype the info here, because I *know* my opener is HomeLink compatible, and I figured out what I was doing wrong... whoohoo!
My handheld transmitters have two settings - 315MHz and 390MHz. In the manual, it says to switch the transmitter to 390MHz to program the HomeLink module. I had done that with my smaller keychain transmitter, but I had forgotten to make that switch when I tried programming the HomeLink with my larger, visor-mounted transmitter. I made the switch to 390MHz, and it programmed the HomeLink almost IMMEDIATELY.
I then pressed the 'Learn' button on my garage door openers and 'taught' it and the HomeLink to play nicely together.
One thing I noticed is that when I use the HomeLink, I have to hold the button for a couple seconds before the door responds and begins moving.
THANK YOU for your help!
I'll still write in the instructions so maybe somebody else can find their solution more easily.
(from the manual) Your garage door opener (GDO) features a unique dual frequency remote control system for reliable service in today's crowded airwaves. Overcrowded airwaves may intermittently interfere with GDO's remote control system. The dual frequency feature greatly reduces the possibility of unwanted interference.
The receiver in the GDO's powerhead can receive signals set at 315 and 390 MHz. The remote is factory set at 315 MHz.
Switch your remote control frequency when:
Remote does not have adequate range.
Remote works inconsistently with fresh battery.
Programming your car's HomeLink system.
To program a HomeLink device: (This GDO is HomeLink compatible.)
Use a small flat screwdriver to switch the frequency selector to 390 MHz.
Follow the HomeLink instructions in your car owner's manual.
Reset the remote frequency to 315 MHz for everyday use.
Cadillac HomeLink module (black rectangular three-button module with amber light)
(Note - unplug the power to your garage door opener before beginning this programming sequence to avoid motor burnout or other damage to powerhead or door mechanism.)
(from the General Motors Service/Parts Operations book)
If you have previously trained a channel on the Cadillac Universal Transmitter, proceed to Step 2.
1. Hold down the two outside buttons on the Cadillac Universal Transmitter until the light begins to flash, then release the buttons. This procedure initializes the memory and erases any previous settings on all three channels.
2. Decide which one of the three channels you want to program.
3. Hold the end of your hand-held transmitter and the Cadillac Universal Transmitter so that you can still see the light on the Cadillac Universal Transmitter.
4. Using both hands, push the hand-held transmitter button and the desired button on the Cadillac Universal Transmitter. Continue to hold both buttons through Step 5.
5. Hold down both buttons until you see the light on the Cadillac Universal Transmitter flash, first slowly and then rapidly. The rapid flashing could take up to a minute or more to start. It indicates that you have successfully programmed the Cadillac Universal Transmitter to adopt the new frequency signal. Release both buttons once the rapid flashing begins.
If you have difficulty programming your Cadillac Universal Transmitter, your Cadillac dealer can assist you or you can call toll-free for assistance: 1-800-355-3515.
EDIT - don't forget to plug the power back into your garage door opener if you unplugged it before programming.

(continued) If the hand-held transmitter appears to program the universal transmitter but does not open your garage door, and if the garage door opener was manufactured after 1995, the garage door opener may have a 'rolling code' system. A rolling code system changes the code of the garage door opener every time you open or close the garage door.
Rolling Code Transmitter Determination: Press the button on the universal transmitter that you have programmed already. If the light on the universal transmitter flashes rapidly for one or two seconds and then stops flashing, the garage door opener has a rolling code system. In a rolling code system, the garage door opener receiver must be trained to the universal transmitter.
Training a Garage Door Opener with "Rolling Codes" (if equipped): 1. Locate the training button on the garage door opener receiver. If you have difficulty locating the training button, refer to your garage door opener manual.
2. Press the training button on the garage door opener receiver for one or two seconds. A light indicator will begin to flash when the receiver enters the 'train' mode.
3. Return to the universal transmitter in your vehicle and press the button you have already programmed for two to three seconds and release. Press the button again for two to three seconds to make sure that the universal transmitter has completed the training process with the garage door opener receiver. Check that the training was successful - your universal transmitter should now activate the garage door opener, and the garage door opener receiver light should no longer be flashing.
I just read that the openers with the amber light are rolling code compatible, and the one with the red light are not. I have the one with a red light. I am not sure I wnat to spend money on another one if it might not work.
Perhaps I will go junk yard shopping and might get lucky . They go pretty cheap in the local yards.
Actually, the GM-printed instructions I have for the Cadillac system mention a red light, and it is rolling code compatible, so I think you're O.K. - I was concerned that perhaps the amber light indicated something different since I have an amber light and I was having problems. But I figured mine out and was successful.
