I think I figured out much of the cause of my MobileKey frustrations - baby got back!

I have a '25 Touring and use (or have been trying to with great frustration) MobileKey exclusively with passive lock and passive unlock both enabled. I keep a Valet card in my wallet as well as a backup.

I have been very frustrated with the performance of MobileKey for me and I think I have figured out why. To date I have been leaving my phone in my rear pocket as I approach and use the auto entry or door handles. It's a force of habit from my Tesla where it never caused issues. The auto entry would rarely work and I would sit there pushing the door handle like an idiot with my family trying to get in the car and nothing would happen.

I just did a bunch of testing, simply by standing next to the car (as you would approach it), using the door handles to lock and unlock the car with the fob in my front left pocket, my iPhone (iPhone 15 Pro Max) in my right rear pocket, and then my phone in my left hand (I'm right handed)

Manual lock/unlock (via the door handles) with the Fob in my front left pocket (and bo phone near) has a 100% success rate.
Manual lock/unlock (via the door handles) with the phone in my rear left pocket (and no fob near) has a low 30% success rate, it is incredibly buggy, does not work most of the time and laggy if it works at all - this was the frustration I was experiencing - totally reproducible
Manual lock/unlock (via the door handles) with the phone in my left hand between me and the car (and no fob near) returns the success rate to almost 100%

Clearly, for my car at least, the Lucid MobileKey does not like my 180lb butt (it's not a huge butt) between the phone and the car? Putting the phone in my hand as I approach seems to clear up many of the issues.

I wonder if this is a common theme for the frustrations with MobileKay and passive unlock expressed here. Just a recommendation for others, take your phone out of your pocket (especially if it's a back pocket) and see if it improves your experience for passive and manual entry/locking, It makes a big difference for me - apparently the big bag of water in between (me) is a particularly bad issue for this car/bluetooth antenna/radio.

Looks like I need to get in the habit of taking my phone out of my rear pocket and having it in my hand as I walk up to the car.

Maybe everybody already knew this, in which case I would be the "Butt" of everyone's jokes.

I think if most people did this regardless of rear or front pocket you’d probably find the complaints about Mobile Key not working would be few and far between.
 
Doesn't work for me. I have the phone in my hand (with the Lucid app on-screen just for good measure ....), and I still have to yell at the car to get the doors to unlock.

Maybe if so it should be suggested here to people having problems as step #1. I have literally never seen it - everybody seems to immediately go to pair/unpair/re-pair, reboot, reset etc, or they say "works fine for me, never have an issue".
 
Also I should have mentioned - all of my testing above was done with the Lucid app closed.
 
I don't think it's the fact that it's in front of you vs behind you, it's the fact that the phone is asleep in your pocket vs awake in your hand. This has been talked about a lot here on the forum. If you did another test with the phone face-down on a cart or something such that it isn't waking up I think you would see a return to the same 30% success rate.

This is correct. You don’t even have to unlock the phone. Literally just take it out of your pocket and shake it for a second. Or just shake it in your pocket, or tap the screen.

If you wake up the phone, you wake up the Bluetooth radio, and it will unlock.

Also, if you’re wearing AirPods or another Bluetooth device that is in active use, you may find your car also unlocks faster… since the Bluetooth radio isn’t asleep.

Nope - phone locked, lying face down on a kitchen cutting board in my left hand - success rate = 100%. Phone then moved to my back pocket, still locked - rate is 30%
 
As soon as I place the phone between me and the vehicle even with the screen off, hit rate goes to 100%. Shaking seems to make no difference. I should probably stop testing this before my wife calls the padded wagon/white long sleeved backwards jacket people on me, LOL.

For me it's definitely having it in my back pocket that kills it. Very reproducible.

Do you line your back pocket with tinfoil?
