I can't sync my new Lexus RX350 2015 with my garage door opener manaras

You won;t need the original openers for the newer garage door openers. There is a button on the back of the opener that you have to push to get the universal remote to sync with the garage door opener. The instructions that come with the universal remote are pretty good in explaining the setup.

You probably need to program the garage door opener,not the car.I have only had to program the Craftsman opener in my garage once(our 2005 Grand Caravan has a built in opener)The opener should have a programming button(my Craftsman opener's button is under one of the light covers).It will probably have the programming instructions near the button(in TINY print).You will want to have ALL of your garage remotes handy(to make sure they all still work after adding the car's remote-some openers have a maximum number of transmitters allowed.

Hold the sync button on the garage door opener located on the roof on the garage. Hold it until the light bulb on the garage dor opener blinks. Hold the remote until the garage door opens or closes. Here is a link to help you out. http://www.ehow.com/how_4614761_program-garage-door-opener-remote.html hope this helps! Please give me 4 thumbs up!

Make sure you have a fresh battery in the garage remote. Drive away about a block and park. Press the two outer buttons on the IS for about 20 seconds , they will flash 10-15 seconds and then go out,erasing any old codes in the car.
Then select a button position, 1-2-or3 on the car for your garage function. Hold your garage remote to the car's button pad and depress the garage remote button and the cars button (1-2 or3)continually. The LED in the cars touch pad will flash slow, then fast then go out. Once these steps are completed the car and your hand held are syncronized...thh car has recieved the remote function. That is step 1 for all vehicles.

Now you need to return to the garage and "introduce" your car to the garage door opener's receiver. Depending on the brand there will be a "learn" button on the garage door opener. You will climb a ladder and push the learn button as per instructions in the opener manual or on the stickers on the opener motor itself, if it is a Chamberlain, Liftmaster or Craftsman....
These buttons will be pressed to erase old opener codes or program to add new devices...which is what your car is.
Each opener has its own series of functions but generally after initial set up of the ceiling unit, you will depress the learn button and hold for several seconds. Then within 30 seconds , you will depress the cars button for about 2 seconds and release, the lights will flash on the ceiling unit in the garage indicating success and the next time you press the cars button the system works.
For complete detailed instructions go to the HOMELINK web site. It covers most cars by model and openers by brand with VERY detailed instructions.
Nice car! Enjoy and post back with results

The buttons inside the vehicle are syncronized/programmed with the operatus that physically opens and closes your garage door, not the operner... The garage door opener needs to have a "programming" feature switch that must be set to "programming" before you can program the buttons inside the car...

There are step by step instructions in your owners manual... This could be a 2 person operation...

I have a 2004 RX and had the same problem, simply because I didn't follow the instructions precisely..

Good luck...Oz

The process is simple but too lengthy to post here.

Check out the Homelink Website. I found instructions for my wife's GS300 there. I haven't tried it yet, so I'm not 100% sure this will work.
