When I bought my 2001 Porsche 911, the seller only had one key for the car. It’s not comforting knowing that you only have one key for your 996. If you lose your one and only key, you’ll have to suffer the inconvenience of being stranded, but also with getting your car towed to the dealership where you’ll be forced to pay whatever they charge you to get you a new key. So, consider getting a spare replacement key.
If you own a 5th generation (2018-2023) Honda Odyssey and you don’t own any CR2032 coin batteries, you should probably stock up as it will only be a matter of time before the batteries in your key fob remotes run out. At that point, you might be stranded if you’re trying to start your vehicle because your key fob’s immobilizer chip is not being detected by your vehicle.
