disabling homelink with ignition?

I was wondering before I attempt to program my homelink button, is it disabled when the key is not present in the vehicle?

The reason I have not programmed the homelink in my 2006 honda is that it continues to function even when the vehicle is off and key is out of the ignition. This presents a huge security concern for me because I frequently park my vehicles on the driveway. My garage houses my motorcycles and tools which could be easily stolen. There has been a string of thefts in the area lately where thieves are doing exactly that, breaking into vehicles and using the remotes to open up garage doors/gain access to valuables. For that reason I am careful never to leave my garage door opener in my vehicles parked outside overnight.

I posted this in another forum but got a lot of smart alec responses along the lines of "just park your vehicle in the garage". This is not an option since half the garage is outfitted as a workshop and I have 2 vehicles. Is there a way to program the homelink so it only works when the SKS is present?
