Like I'm sure many of you have, my remote garage door opener on my new Telluride is programmed to a button on the rear view mirror. Just for grins, I unlocked my car from within the house and went out without the key fob to see if I could open the garage. I could! That is not a good scenario! Most of the time, my wife parks in the garage with her BMW and the Tele is parked out side.

I could envision that, while wife and I were away with her car, someone could potentially smash the Telly's driver window, reach in and open our garage - then rob us blind.

I wonder how hard it would be to re-fuse that circuit to a fuse location that requires the car to be on for that button to function? Any thoughts?

I might have to look into that.

They could also break a window to your house and get in. I have had both scenarios you speak of with different cars and the garage door opener working/not working when car not on. Personally I prefer it when I can use when keys not on car, have had to use more often than not. Not sure if you could change it.

You peaked my curiosity with this. I just went out to my Telly and locked myself in it, without the key, using the app. Waited about 5 minutes with the doors locked and pressed the button garage door opener. It opened. Not happy about that needless to say. :mad:

That would be difficult on my house. Bars and very nasty yucca plants below windows. Also, if they did get into the house they would be met by a very protective dog.

This would be a simple fix too - just wire the mirror buttons to a fuse that is only on when the car is running.
 
This concern has been raised before.


Majority of car owners leave their OEM garage remotes in the car at all times too, which also work regardless of the car being off. If this were a huge problem for all garage owners, it would have been addressed by now.

We only leave our OEM opener in my wife’s car which is in the garage, I agree it’s probably not a big problem, but depending on where you live it could be a concern. If not a concern for you then don’t worry about it.
 
Most garage doors have a button in the garage for you to operate the garage door. There is a feature that all you need to do is hold the lock feature for a few seconds and then the garage door will not open no matter the method attempted.

I mean, if you got the dog, isn't it the same scenario if they broke in through the garage vs. a window?

If you're worried about this, then you'd probably want to remove any garage remotes from the car, and deprogram your Homelink. Problem solved.

No, the dog is in the house. If they got into the garage they could steel literally thousands in expensive tools and never encounter the dog (car restoration is one of my past times). BUT, I’m not actually worried- just having a discussion about a design factor I think they should address, if not now then in future designs. It would be an easy fix. Speaking as an engineer (EE), I would not have tied that circuit to an always on power source.
 
Question would be whether the memory on the mirror is volatile or non-volatile. Assuming it was non-volatile, you should be able to just re-route the pin for constant power in the mirror connector to the ignition keyed power. That is either solder, tap, or jam in the mirror's red wire to the turquoise pin out.


Personally, I just never program the mirror remotes due to the extra security risk. I use little keyfob remote clickers with slide covers.

Good idea

Too funny...over on the Jeep Wrangler forums, members complain of the opposite. The HomeLink buttons only work in the Jeep when the ignition is in the "on" position. That is the first vehicle I have owned that works that way and years later I have still not been trained to hit the button before I shut it off. It is frustrating.

It makes more sense on a soft top Wrangler that most folks don't even lock....thought process to break a car window just to try opening the garage seems pretty convoluted for most thieves.
 
My 2015 Sonata would open the garage door whether the ignition was "on" or not. My 2021 Sonata requires the ignition to be "on" (regardless of whether the engine is actually running). I have to say I prefer the ability to open the door regardless of the ignition status, although I, to, have a garage full of expensive things. No dogs though. :)

Hmmmm - I have a 2021 EXP - I purchased the auto dimming mirror separately and had the dealer install it before I picked up the car. I can only open my garage door with the Homelink button when the Telluride is running. If the car is not running, the garage door will not open.

Boo (or yay depending on your viewpoint). Sounds like your dealer had different ideas from the factory when they wired it up.
