I keep getting a notice that my Key Fob battery is low on my dash. I have replaced 3 times in the past 2 weeks. Is this a known issue or are all my batteries drained? Is there a way to check FOB battery levels?

Might you be using bitterant-coated batteries? These can cause problems. You can remove the bitterant by wiping the battery with rubbing alcohol.
 
Ensure that the fob is far enough from the car to prevent the two from communicating; I'd estimate 20ft. A stronger measure for this is to purchase a faraday box [Link]. The distance will no longer matter, and you'll get the added bonus of anti-theft via RF boosting. Since I started using this in Dec 2024, I haven't changed the battery once; but that's just my anecdote.

The other suggestion of removing bitterant is also valid, or finding batteries without the "child-safe" logo on the packaging.

Another thing to check:
  • Purchase Panasonic (Lucid recommended) or Energizer (I trust the brand) batteries from another store. I once had 4 bad batteries in a row, all from the same batch.
