Well in that case the only solution may be to keep an extra battery in your wallet I suppose.The key slot does not always help, like in my case. It’s gotten me a bit worried. All our CR-V over here were modified by the dealers to prevent Lithuanian car thieves (we have a real infestation of them) from stealing every single one. The key slot was disconnected from the actual lock mechanism leaving just the fob to operate the locks. I was just preparing for winter last week, greasing locks in all my cars when I remembered it.
Which is why I never keep my vehicles locked in our garage.. which honestly is where most of my "failure to start" events have happened.Yeah, I'm more worried about the main battery going flat.
