I bought 2 OEM Tesla Homelink kits on eBay for $169 each For my 2 2023 model Ys. Part number 1114984-00-B
The same seller “element1-7“ is now selling them for $189
Kit included module, bracket and screw. Followed YouTube installation instructions. It took less than 20 minutes working very slowly to do the hardware installation. Just needed A 10mm driver or socket and a flat blade screwdriver.
Activating it was pretty easy also. Only tricky part was I had to exit the car and close the door to allow a 2nd reboot for the Homelink to show active.
When within range of the activated garage door the icon pops up on the top of the screen. See screenshot attached.
I set it up to automatically open the door when arriving. I didn’t set it to automatically close because I want to verify with my eyes that is actually closed before driving away.
