No way to stop the thefts completely, but I feel like using multiple deterrents to make it so you aren’t the east target is your best bet to keep most thieves looking elsewhere. 
I plan to relocate my horn, add some sort of tracking device (AirTag or old cellphone) and a version of what Jimmy07 is suggesting.
The problem won’t stop until the thieves are no longer able to program new fobs, requiring a code that you must call into a tech line for like many radios over the years have required would be a good option.
