That is why I always open the door and push the learn button on GDO so I can quickly go to the car. Also ignition should be on for the car. When code is learned door starts going down.

 

Both our 2018 and 2012 RX 350's have very weak HomeLink signals. We have to be right up on the garage door to make the car talk to the opener. But my Honda Ridgeline truck can open the door from 100 feet away. Is there a cure for the two Lexus cars?

 

Google something like "how to expand the range of a garage door opener". Do it at the garage door antenna - not at the vehicle.

 

likely interference by surrounding wireless systems.. they all broadcast within a specific range, I believe most garage door openers work in the 288 - 433MHz range, however there are a large number of things that can interfere with this range, from Wi-Fi networks to Cordless phones, Air Conditioning systems to Various lighting products.


we had an issue with ours as well until I switched my Wi-Fi to an alternate channel, I did this because I was having Wi-Fi issues with a neighbor who was using the same broadcast channel, and I had to switch mine to recover my Wi-Fi signal in one part of my home that his signal over rode, lightly because his router was closer to that side of the house, when I did this I noticed the homelink started working from several hundred feet away. As my Wi-Fi and Garage Remote smart home unit are close together I caulked it up to changing the channel on the Wi-Fi from the default channel 6 to something else less common.

 

 

Thanks to those who replied. These are ideas I never even considered...will give them a whirl.

 

I would also make sure when you program the Homelink in your car, make sure you have a fresh battery in your garage remote. If you program it with a weak signal, the Homelink will have a weak signal. Sounds weird I know but that's how it seems to work.

 

Lol....think of the fun you could have, driving down the street, holding down the garage button and seeing what happens!

 

I had this exact same thing happened with my IS350.... basically it turned out to be programming/sinking with opener. Look in youtube for proper way of programming homelink to the correct device opener that lifts up your door. I believe I had to put a ladder ready and had to press something at the opener motor and then come down to the car withing a few seconds to get it to work.

 

I had a similar problem that ended up being a neon light in my garage was interfering with my RX remotes. Once removed from garage everything was back to normal. Just my 2 cents.

 

Of all the RX's I've had this 2017 has had the weakest homelink signal. Wonder if it has something to do with the radar and automatic braking systems.

 

Mine works from at least 100 feet away, no different than other cars I have had.

 

I had the same issue. My range initially was about 200' line of sight, then it 'intermittently' dropped to about 30'. Turns out that when my LED landscape lights are on it diminishes the range substantially. I haven't figured out a way to reduce the impact of the LED lights, but at least I know that in the evening I must be in the driveway before the door can be opened.

 

more likely the transformer you use for the lights..

might try a different brand/model

 

I have a relatively new garage door opener. My older RX was able to use homelink on the auto. I am having trouble getting my new 2018 to "learn" to use the homelink.

I followed the manual, since opener has rolling codes. Pressed the learn button on the back of the opener until red light went on. Then quickly got into car and pressed and held one of the 3 homelink buttons for 2 seconds and did this 3 times. Now it still does not work. HELP!!
