I would think that is a great question for Homelink. My guess is that you need the opener system to pair it with, that is, the actual garage door mechanism.

I believe any of these openers that don't have a pairing mode are vulnerable to having the codes harvested out of them with a simple learning remote.
Is the opener disabled in valet mode? That would offer at least a small layer of protection.

I always thought it would be a good idea if you where a dishonest person to get a job at an auto dealer and for cars kept overnight get the keys, in the Nav choose "home" and open the garage door. Now you are inside a garage and can pack many items. Many people leave the door leading to the garage to the "mud" room unlocked.
Many car dealers do NOT lock up the customers keys.

I lived in McAllen, Texas for 4 years in the 90s. This occurred quite often. My neighbor has their car stolen after a visit to a dealership. As a co-worker would say quite often "the bad guys stay up at night trying to figure out a way to rip you off, because that is their job".

There are "code sniffers" out there used by pros that can clone fobs or garage door openers.
But - I would be more concerned about leaving a house key attached to the fob. Your address is on the work order.

I can't imagine leaving my house key with a business. I've always used those detachable keychains.

I use a simple method. I have the remote clipped to the visor.
When, i leave the car at the dealer, i take the remote and the house key with me.

Fob and garage door openers are totally different then they were back in the day. They all use rolling code technology, so the code is changed after a one time use. Cloning a code gets you nowhere because it will have changed before you can use it. Door openers have used Security+ Rolling Codes since 1993, and in 2013 the openers were upgraded to Security+ 2.0, which supports smartphones. If you still have a 40 year old opener that still uses dip switches, then the code can be obtained. But I doubt the opener in modern cars will even work with those old systems.

Sorry, this is for the Liftmaster and Chamberlain line of openers, which most other opener manufacturers also used the same technology. The majority of companies were using the 390 Mhz system that had Security+. I just looked up the 315 Mhz system you have. The 315 Mhz system moved to Security+ in 2005. You can update it by buying a $30 390 Mhz module that connects to the two wires that go to the opener, and deactivating the the old frequency. That way you don't have to replace the opener to be more secure.

One can use a local intersection programmed as 'home' in my NAV but that doesn't keep a thief from learning your home address by looking at your car registration if you keep it in the car (as required by some / many states). I've got mine on the floor of the cubby behind the display where it is hard to find.

How would a thief get a hold of your vehicle to drive to your home?
