If you haven't already done so, go to the garage door motor manufacturer's website for their instructions. I've had several WK2's that never took more than a couple of minutes to program 2 garage doors.

 

OK thanks, i'll try that if i can find their website as I lost the door opener's Owner's Manual.

The initial problem i had was step 1, resetting the system.
By simultaneously pressing the I and III buttons there's supposed to be an orange indicator that the system did reset.
Never got that indication and tried it a few times.

Gonna try it again today and hold those buttons longer.
Maybe the sunlight from the pano roof obscured the orange LED?

 

Find your manual online with a quick google search. My door's manual had explicit instructions for Homelink programming.

 

I had a horrendous time trying to get my 2014 programmed. Followed the confusing instructions in the owner's manual over and over. After half a dozen tries it finally seemed to work. By contrast, I just got a 2003 Accord with what appears to be the same built-in homelink system. The Accord owners manual instructions were far clearer and it only took me one try to get that car programmed to the same garage door opener.

I think the Jeep manual has mixed up the instructions for old and new types of systems causing you to include not only an unnecessary step when you have a new system but a step that screws it up. But I was not able to figure out where it was going wrong, I just kept trying different variations one what to do and when. below is Link to the Accord instructions, try them. Go to page 198. There are two systems in the instructions, read both and proceed based on what you have. It says to unplug door opener. That's for safety. You don't need to unplug it if it won't hit anything when moving.

Also.. I found the range was very poor, nearly had to be on the driveway for it to receive the signal. I made the antenna on the door opener longer. Measure its length and then add additional wire to make it twice as long. That tripled the distance it would receive from.

Horrendous! That was also my worst fear after just glancing over that voluminous procedure in the Owner's Manual.
I'll check out that Honda link.

 

I programmed one of the three opener buttons in my 2018 GC to work with my garage door last year. I don't remember the specific steps involved but it was rather easy. I think the majority of it had to do with the garage door opener TEACH or LEARN buttons and all I did on the GC was press the button I wanted to use and held it for a few seconds.

Yep, that's how mine was. Old style opener. Hit the LEARN button on the opener and slide down the ladder, rush to the car, and push and hold the remote button a few seconds. Can't remember if the button LED comes on solid and you hold it until it flashes or if it comes on flashing and you hold it until it turns solid.

 

I have several stand alone remotes, and programming the Homelink in my GC didn't affect any of them. As I said in an earlier post, your garage door opener manual is a great source of instructions for programming. They are available online. What brand and model opener do you have?

 

Took a long time but finally found the Owner's Manual.

Its a LiftMaster, Premium Series Door Opener.
www.liftmaster.com

Thanks all for letting me know their is another source for programming these things other then the GC Owner's Manual.

Its good to know the manufacturer has hopefully clearer instructions on programming Homelink capable vehicles.
And that programming my GC probably won't affect my other remotes.

Gonna look over the manual and their website sometime this week when i get time.

On another note really a LiftMaster rant,
one negative thing i will say about the LiftMaster is that it uses infrared or laser beam sensors as a safety feature to keep the door from closing on someone's head.
Problem is certain times of the year when the sun hits those safety sensors just right, the door refuses to close falsely detecting someone is in the path of the closing door.
Unfortunately my garage door faces the South.

 

Just did our 2015 Limited with brand new Liftmaster opener without issue. Just followed the instructions in the Jeep owner's manual. Not as complicated as it looks. Did the same with an older Craftsman opener.

If you have a learn button on the opener's wall switch plate, don't use it for this. Use the one on the opener.

 

Interesting. I use the learn button on the wall switch for my Liftmaster and three cars with Homelink every time I change something. Also, I periodically clear all memory in the openers (two doors) and resync them with the cars because it seems when relatives come, my wife likes to have them sync their openers with our garage door if they will be here for a while. I like to get rid of that stuff.

 

I'm gonna try this maybe sometime this week and will update.
My worst fear is i'll somehow screw up the remotes that came with the LiftMaster.

What could possibly go wrong!

Its not my idea of fun opening that heavy garage door of mine manually.
Been there done that more times than i care to remember during power outages.

 

When you push the "Learn" button on the power unit, only push it for ONE second. If you push it for several seconds you'll roll the existing codes and be starting from scratch.

 

One thing we found was that the system seems to be sensitive to distance. We couldn't get ours to program when it was right up against the garage door but it worked the first time when we moved the Jeep back down the driveway a few feet.

Also, the infrared safety beam is designed to go straight across the door opening. If sunlight is affecting it, you can add a shield to keep light from the side from reaching it. Some soft dark plastic rolled in a cylinder and held with an elastic band will do the job nicely - kinda like the light shields they put on some traffic lights.

 

Thanks, i'll keep that tip in mind.

Back a few years ago when i first encountered the sunlight door refusal to close issue, i contacted LiftMaster for any fixes.
They sent me free of charge a rube goldberg origami sunlight shield.
It didn't work. Waste of shield folding time.

What seems to work at least so far was to jury rig the sensor brackets so the sensors themselves were re-located further back into the garage maybe an inch or two.
Then i re-focused the sensors.
Hadn't noticed the problem since...so far that is.

IMO i would not recommend this door opener for garage doors facing the South.
Might be OK for far Southern States where the Sun doesn't set low in the horizon certain times of the year. Just a guess.

 

I had problems with linking my Jeeps to the Liftmaster units.

Ultimately, I was not waiting long enough after pressing the learn button on the Loadmaster for it to flash the ready code led. Previously I just assumed that the learn led was burned out.

Once I learned that step (two months later) everything linked easily.

 

I had a difficult time programming mine until I realized that every time I got off of the ladder and ran to my Jeep I crossed the infrared safety beam which would stop the programming. It worked when I carefully stepped over the beam on my way to the Jeep.

 

Thanks for that tip.
Would of never thought of that.
Thats one thing i'll definitely keep in mind.

 

My 2014 programmed easily and since I only have one garage door, I programmed all 3 buttons for it. Very easy to just push one of the 3 buttons instead looking for just 1 while the other were not being used.

 

I’ve never had any issues adding new garage doors... as a tip, park in the garage just under the opener if you can so you can stand on the door sil to reach the button on opener.

But wait there is more... I programmed the gate remote to the community to the car by using the other method in the manual. Holding the old remote near the homelink in the car and pressing and holding the old remote while holding the homelink program combo. That also worked... took a couple of try’s as I recall but worked fine

Thats the exact method the guy in the video used as i mentioned when i 1st started this thread.
Thats why i thought this would be a breeze.

I tried it briefly today.
Reset by pressing both the I and the III buttons.
After a few seconds the red LED blinked and then went solid on and i seem to remember off, i forget.
Then pressed the I button while transmitting from my LiftMaster's remote.
Didn't work. But gonna try it again.

I really don't understand why the LiftMaster unit needs to be involved at all.

The Homelink system in the Jeep should be able to interpret the remote's transmitter's format and code, copy and store it into memory and walla.
Gonna try it a few more times. Might take some trial and error.

 

this thread is awesome

 

The reason the Learn button on the door opener head must be used is because newer openers using rolling codes. With the old static code systems, it was a simple matter of getting the Homelink to produce the same code as an existing remote. Rolling codes are somewhat like Bluetooth where you have to pair the transmitter with the receiver.

I never had any trouble with the first step of the programming (holding the old remote next to the Homelink buttons), it was the second step with the Learn button that was frustrating. I eventually found that the "press the button twice for two seconds each" instruction was the problem... the two second time was wrong. It's been a while so I can't remember if it was too short or too long. Try it with pressing and releasing the button for less than two seconds each time and if that doesn't work, try it with holding the button longer each time. One of those should work.

The "2 second" thing in the instructions did NOT work for me either. I used my watch and was letting go of the button at exactly 2 seconds. Finally watched the Homelink video and they said "about 2 seconds" or until the Homelink LED (either quit flashing and turned solid or started flashing). Can't remember which way it went. It actually took about 4 or 5 seconds.

 

I had a newer Chamberlain unit with the 2.0 'rolling codes' technology. I could NOT program my '15 Grand Cherokee. I'm sure the Homelink system has been updated in the new models but I had a hell of a time figuring this all out.

I ended up buying this. My GC paired right up and works fine now.

Well i'll be danged!!

As i mentioned a few days ago, i used the method of placing the original remote next to the I II II pod while pressing both the original remote and the I button.
It didn't work back then.

Fast forward to today.
While sitting in my garage ready to pull out of my garage something compelled me to push the I button.
For kicks i tried it, what do i got to lose.
What the hell the garage door opened!
Shocked the hell out of me.

Once out of the garage, i pressed the I button to close the door.
NO GO. Didn't work.

Later when i returned back home tried the I button again to open the door.
NO GO! Didn't work
BUT, i tried again by pressing the I button for a couple seconds and Urika!
The dam door opened.
Once in the garage, pressed the I button for a few seconds and the dam door closed.

Don't know what to make out of all this.
Maybe my door opener is of the earlier variety but it was installed only 2 or 3 years ago.

There's one thing however, whatever's going on , it appears the range is VERY limited when it did work.
Maybe i'll try increasing the antenna length on the opener.
If that don't work then i'll just settle on using my original opener's remote.

Some progress at least.

 

Well i'll be danged!!

I've always had to hold the Homelink button in for a quick 3 count to open or close the door. It works out to at least 120 feet.

 

I didn't have any problems with two different Liftmaster openers, but I did have to push the learn button. On my old Craftsman opener, all I had to do was hold the remote next to the buttons (it has a learn button, but I didn't have to use it).

On a side note regarding the laser and sun issue, I have all my lasers screwed to the top of each opener about 8" apart. Not hard to initially adjust, and haven't touched them since. Although, it's not very effective in reversing the openers if something's in the way of the door closing.

 

What I do is put them at bumper height so that the door won't be closed and hit the back of my cars. Before I set them up like that I had two cars get their bumpers dinged because they were not quite in that last inch. I also took the grab handle off the inside of the door which gained another 1.5 inches of safety clearance.

Holding the LiftMaster's remote while pressing its open button near the Jeep's I II II pod worked for me.
Maybe i lucked out somehow and it didn't affect any of my LiftMaster's OEM remotes which i use in my other 3 vehicles at times when i need to get them in the garage from my pole barn.

I did have an initial problem where i had to be close to the garage door for it to open with the Jeep's HomeLink.
When i looked at my LiftMaster, its antenna was coiled up inside the unit.
When i dropped the almost foot long antenna wire the Jeep's HomeLink can now open/close the door i'd estimate 50 to 75 yards away.
My long driveway from the street to my garage is roughly 50+ yards.

 

I just programmed the opener in my new 2019 GC Limited. I watched the Mopar youtube video

I have an older rolling code Craftsman opener and had to use the 2 step procedure. After clearing the Homelink by holding the I and III buttons I had to hold the original Craftsman opener a couple of inches from the Homelink unit press the button on the Craftsman remote AND the I button (or whichever you want) on the Homelink at the same time until the Homelink went through the learning process. Then I had to push the Learn button on my door opener and, within 30 seconds, get back in the car and push and hold the I button until fast flash. Worked first time when I did the full procedure. I had already tried just using the Learn button on the opener and holding the I button but it never synced. So I did the two button "clear" and used the old Craftsman remote "clone" and then the opener "Learn button" and that worked. I believe that same 2 step process is what I had to do on my 2015 Chevy truck.

When I first programmed mine, I was able to program I for the left hand garage door and III for the right hand. Then, to be quirky, I programmed II to work both of them by programming first the right and then the left into the II button (actually, I believe the data is stored in the openers). That way, if I wanted to open both, I just pushed II without the risk of erasing everything by pushing I and III together.

I later changed this so I could program my daughter's garage door in for when I visited her.
