The key fob has been a disaster since day one. I’ve had mine replaced twice and every technician has commented on how frequently they replace the fobs. Why Lucid hasn’t addressed this issue is disappointing. I have had batteries last as long as 4 months and as little as 2 weeks. Just keep extras in the glove box for safety. The low battery in key fob signal does come on but literally stays on for like 2 seconds so if you aren’t looking you’ll miss it.
