Does that work? When I did this with the delivery agent, it disabled the mobile key. It would only work with proximity enabled.You already can?
Set up mobile key and disable proximity lock/unlock in the car’s settings.

I haven't tried it in a while, but I used it like that for a few months without issue. The old iOS app / current Android app had a rather confusing warning message when you did that which looked like mobile key was disabled, but it worked anyway, that was just a UI flaw.Does that work?

Well hell, this whole time then I maybe thought this wasn't possible just because the app told me so - I always had the fob so I never actually tested it beyond that.I haven't tried it in a while, but I used it like that for a few months without issue.

I had service visit me at home in mid November 2024. Winston was the tech's name, and we discussed fob battery life. He told me that Lucid had lowered the fob advertising rate to extend battery life. He also told me that if I am near my car and its not sensing the fob, to shake the fob and that should then wake my Lucid,. Apparently, the fob has an acceleration feature to wake it up to send a signal to the car. I've not had to use this feature yet to wake my car, so haven't tested it.Thanks again Bob. The variabity we are hearing about may also be caused by a change in chip vendors. From the table I posted, different chips have different lives. I also wonder if they lower the advertising rate according to not hearing the mothership. That would be a terrific scheme to increase battery life (and justify the Faraday bag.) Fob battery SOC could be roughly measured from its battery voltage. FYI - I try to stick with Energizers from Amazon.
I wish we could hear from LUCID with real info and ideas.
"Tens of thousands?" Are we there yet?Sometimes I feel bad for these posters, because:
I can not think of any car, at any price, that I'd rather have....

Lucid: A wonderful car insulted by a poorly designed key."Tens of thousands?" Are we there yet?
But what is very annoying is that I could just breathe on the fob, and the car will wake up in the garage a million times.
But when I'm out, getting groceries or whatnot, I look like an idiot shaking my keys in the parking lot, just so the trunk can open.
Great job. Too bad Lucid doesn't listen to their owners...Being an Electrical Engineer I was curious about the key fob short life mystery, as it has hit me also. (New 2025 Air Pure). So I made some actual measurements
First, the Fob is made by a British Co. called Pektron. Their website has no Specs on it.
Next I took a microammeter and measured the current draw under the 3 conditions below:
1 - Qiesecent (far away from car): Very variable, changed about once per second in range from Approx 10 - 200 microamps.
2 - Pushing the button = 800 microamps.
3 - Sitting in car, with car on and in drive. Similar to #1 but seemed to peak at 400 microamps.
Let us reduce each of thse peaks by 1/2 to account for the duty cycle of the pulse in order to get an average draw. Thus, the averaege draw is about 100 - 200 microamps. More precise analysyis would require an oscilliscope.
The CR 2032 battery in the fob is rated at 225 mah = 225,000 micro-amp-hours. Thus, doing the simple math, at 200 microamp avearge draw it would last 47 days. At 100 microamp average draw it would last 94 days. At 50 microamp average draw it would last 188 days = 6 months. That is what many of us are noticing.
Conclusions:
1 - The fob must be scanning or has a high quiesent draw that is pulsed in some way to reduce average drain. A Farady shield is not going to fix this.
2 - None of my other cars have this problem. So better designs are possible.
3 - I am starting to think that Lucid owes us a new fob
A quick fix would be to add an external on-off slider switch in series with the battery.
Cheers,

The fob works as a nfc key card. That's why the fob is superior to the phone.I also faced the issue with one of my fob key for Lucid Air Pure 2025. The battery got discharged in less than a month and can't accept if something like this happens in a place where there is no internet/cellular connectivty.
Gravity key solves these problems. Air is stuck with these keys as I understand it, but my mobile key works great. Hopefully they can get it more consistent across the fleet but lately even having my backup NFC card in the wallet has seemed a bit superfluous… yet I know as soon as I take it out I’ll be stranded somewhere lol.I love that picture!!!! Thanks. I see at least 3 paths now:
1 - Live with it or use the mobile key. (Not for me.)
2 - Rube Goldberg. Fashion a new case or leather key case that would hold a CR2 or larger CR123. That method might include removing the electronics from the old Lucid key and putting it into the new shell or case - perhaps also including a proper new physical button. Are there any folks listening with access to 3D printing capabilities here? I'd glady pay $50 for a new shell.
3 - Pressuring Lucid for a proper key, including legal efforts. Are their any attorneys listening? Does the Gravity key solve this problem? It has nice needed physical buttons.
Every other car I have driven, including cheap barebones rentals, does not have this problem. I'm sure that Lucid could have found a key vendor to do a small run of generic keys with Lucid coding. Instead it appears that they picked a vendor that does high end stylish keys but ignored the power budget.
