Cr1632 battery for key fob urgently needed

[Hollis]

Hi Oak! Happy almost Thanksgiving!

Sadly, in my car the key only opens the door, but doesn’t work to start the car. Hopefully, all is well now and I’m going to have a backup stash of the little batteries for the future.

Make sure your interior dome/room lights are off, those can kill a battery overnight, depending on the battery's state of health and charge.
You can charge a battery and the car may start, once, or twice, but if it goes dead again, the battery may not be capable of holding a charge due to age, lack of use, or a handful of other contributing factors.
Best recommendation, read your owner's manual. Knowledge is power, within reason :O)
