So if your FOB battery dies, how do you open the doors?

I actually had a scare with this last month. FOB battery died, but key would not unlock drivers door (apparently something is not right inside the door). Fortunately was at a WalMart and ran back inside to buy a battery.

if your battery is dead in the fob, just hold it as close as you can to the push start button. the car should still sense it and start. Read that in the manual but the guy in the finance office explained that to me as i was signing the paperwork on my 15 EX.

Part 2 of this exam question. What if the battery in the crv is dead. Fob is fine. How do you open the tailgate? Example: kids left the lights on over the weekend. Now car battery is dead. Your booster cable is underneath the trunk cover by the spare. And the tailgate won't open.

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.

Well in that case the only solution may be to keep an extra battery in your wallet I suppose.

Yeah, I'm more worried about the main battery going flat.

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.

Then again.. I also run a full maintenance check and trickle charge top up on my vehicle batteries every month or two as well. This has enabled me to see a failing battery early in it's failure slide.... rather then getting surprised by it one morning in winter season (even though our winters are very mild here).

If parked out somewhere while out for the day... that is why I have HondaCare.... because if the vehicle ever fails to start .... even well after the factory warranty is expired... I know I can get it towed to the nearest Honda dealer and they can deal with why it won't start, and perhaps might not unlock either.

For the keyfob battery... I believe that when the battery is low, the fob will tell the vehicle and the vehicle will give the driver an alert message.. so you can change it before it actually stops working. But since you can unlock the drivers door manually, and start the car even with a dead fob.. I don't see a big issue even if the vehicle does not alert the driver of a low fob battery.
