For the first couple of months I had trouble with the key fob = it kept waking up the car, flashing the lights, flapping the door handles, any time I went into the garage. Then after a month or so it stopped: the battery was dead. So I bought a dozen replacement batteries and a key fob Faraday pouch. Problems solved.
Then on Bobby's endorsement I switched to the mobile key on the app. Now the lights flashed and handles flapped from a much greater distance; pretty much anywhere in the house or within 30+ meters in any direction. I thought I had to sign out of the app on my phone to stop it, but my kid showed me that my Lucid app was "on" in the background, even though it wasn't on the screen. He showed me how to "silence" the Lucid app by touching the line at the bottom of my phone (Pixel 5a) screen and dragging it up about 3 cm, then lifting my finger, and it showed all the apps that are running in the background. a slow swipe to the right exposed the "clear all" button, and by pressing that, the Lucid app (and all the others that were active in the background) "closed".
Now I can be "near" (range is about 30 meters or more) the car with my phone without the car "waking up". Neat.
So I put the key fob (in the Faraday pouch), and the spare batteries, in the glove box, for the service people, and use the phone exclusively.
It's important to practice using the wallet key card, and the dead (battery-less) fob on the "B" pillar sensor. The dead fob works the same as the wallet key card = by holding it above the camera on the driver B pillar. It's important to remember your car sign-in code.
But if you are doing valet parking, I give them the fob I keep in the glovebox (in it's Faraday pouch), after checking that it works.
I have to emphasize that the fob eats batteries if you don't use a Faraday pouch. That was the reason I was having "short range & delays" issues = weak / dead battery (or with the bitter coating ).
Anger issues over the key fob is part of the Lucid experience. Enjoy it.
