Went through 2 key fob batteries in two months. Likely issue is key fob stored too close to car (in my case, in kitchen drawer 33'4'' from car), which causes fob and car to continuously communicate. Solutions: (a) wrap fob in aluminum foil when not using (suggestion from Lucid Service Dept.), (b) get a Panasonic brand battery with lifetime replacements ($21.99 at Batteries+Bulbs; they'll replace unlimited number of times); and/or (c) buy a Faraday key fob pouch, which blocks all communications to/from fob (e.g., 2 Faraday fob bags available from Amazon for $9.99) for storing fobs when not being used. I've purchased the Panasonic battery for one fob and have ordered the Faraday bags from Amazon. I'll let you know if this resolves fob battery depletion issue. BTW, Lucid should put its logo on Faraday fob bags and give them to new owners when car delivered.
