You have to look inside the opener motor suspended from your garage ceiling for the color of the "learn" button.

This article explains the differences in technology, and when they were introduced for sale, for openers with red, yellow and purple "learn" buttons:

Funny I bought a new liftmaster wifi unit 2 years ago. I could sync up my 2010 Lexus and my kids 2015 Audi A4 but my 2012 XKR would not work. I had to call the liftmaster hot line and complained about it and they sent me one of their converters. Got everything working and it's all good to go.

 

The service bulletin from Liftmaster was in September, 2011. See the attached document.

I wonder if 2012 XK has Security+ 2.0 or not.... I'll check the website

 

My liftmaster unit is 2 years old and my 2012 XKR will not make it function without the special receiver unit from liftmaster.

 

 

The only way I could get my 2015 XKR to work with my Chamberlain 2015 garage door opener was to purchase the HomeLink bridge repeater kit 855lm. Amazon Prime for about $25. Fought with the car and the garage door opener for about 3 hours attempting to program without the bridge. With the bridge the car was synced and operating correctly in less than 5 minutes. Home link indicates that any opener with a "yellow" wire antenna hanging from it (mine has yellow) will need the bridge. You find this in the small print after answering all the questions on the HomeLink web page told me I shouldn't need the bridge. I thought $25 was worth a roll of the dice. Works perfectly. Hope this helps.
