My car’s #2 key fob is dominant, so my car defaults to that fob when both keys are in the car. My husband has to stand 20 feet from the car until I start it with my key. Not a problem ordinarily, but we’re planning a cross-country trip and need both keys in case one is lost or not working.

I don’t know if this would work. Wrap one set of keys in aluminum foil.

Can you remove the battery from the key fob?

That’s what the dealer suggests, but they’ve never tried it. We’re going to test the aluminum foil today. When I had to exchange my I-Pass, I was instructed to wrap it inn foil so it didn’t register every toll between Wisconsin and Chicago. Thanks for the suggestion.

The dealer says I could remove the battery, but that it’s not easy and I could find myself far away with a non-functioning key fob. The dealer is stumped. They can’t understand why I would want both fobs in the car at the same time, but we’ve experienced the lost-key scenario and don’t want a repeat…

I’m a little lost on why what key it thinks is dominant is an issue. You can still set the seat and mirrors to your settings by pressing the appropriate memory button. When my wife drives my TL, it sometimes picks up on my key, but she just hits memory-2 and everything’s configured for her.

I have a 2018 Acura RDX and have had several other Acuras with the same fob. When i am with my Wife, we have learned to have the driver approach the car first as the seat may adjust to the closer key fob. I believe the key fob recognizes the driver when the door is opened, or when it is close to t…

If you unlock the car using the button on your fob as you both approach the car, does this avoid the issue?

I’d go the foil route or the small metal box (maybe an Altoids-type box?), not the battery removal. Maybe a foil-lined glasses case?

Thanks for the suggestion. My Key fob #2 actually overrides the #1 setting unless the car has been turned on. We think it is a defect in the fob or in the way the fobs were initially programmed (by the salesman, since we’re older and technology challenged). When we discovered the issue, we found th…
