I decided that I need to keep the keyfob in my pocket every day, just like every other keyfob I ever used, and I don't want to walk around with a Faraday bag. Hence, I am starting to build my much smaller keycase based fob holder. Here is the battery I just ordered - a CR2477. It will have over...

Thanks. Good info!

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...

I was not able to find the exact protocol, but did find this: "Advertising and discovery BLE devices are detected through a procedure based on broadcasting advertising packets. This is done using 3 separate channels (frequencies), in order to reduce interference. The advertising device sends a...

B.B. Others have also reported success with the Fraday shield, but in my tests far away from the car fob, battery drain continues above standby at a high pulsed level. I had assumed that the Fob sends out a (battery draining) burst every second or so to see if the mothership responds. That...

As I have said in the past, in my opinion, the Lucid Air Keyfob is stylish but as poor in any other aspect as one can name, especially including battery life. In an effort to fix mine, I made conversion Model #1 shown in the figures below. It utilizes the original keyfob with an external CR2...

Same issue, but no big deal.

If my guess is correct, the Farady shield will have no impact. My guess is that the fob is advertising itself too often for the size of the battery. My hope is that the RG1 or RG2 will fix it. RG = Rube Goldberg. Stay tuned for next week's adventure.

Progress Report: I emailed the fob manufacturer with questions, but no answer yet. Parts of my 'Rube Goldberg' solution (leather key case, larger CR2 battery and holder) are starting to arrive. I estimate about 1 week before I can build that. Meanwhile I looked up the BLE (Bluetooth Low Energy...

I garre - it a great car, especially after I learn more about how to drive it. The fob issue is like a stone in an expensive shoe that we love. I wish that Lucid would offer us or sell us an upgraded fob or tell us more about the technology so we can find somone else to fix it.

I odered all the parts for my Rube Goldberg solution: CR2 battery and holder, leather key case. Total cost about $10 + $10 shipping. Will arrive in about a week. I'll keep you posted. Meanwhile, I know Lucid tech folks are litening to this board. They should have the specs on the chip and...

That makes yours 5 1/2 months old. Please have a fallback. I think that yours will fail vey shortly. if you have a way to meaure the battery voltage of the old battry, plese report.

DeaneG: How long does your key battery last? What year is your car? Thanks!

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...

Here some 'Rube Goldberg' type solutions I may try. A CR2 battery is larger (15.6 x 27 mm) but has a capacity of 850 mah, about 3.7 X that of the CR2032 in the Lucid key. That should give about 1 year of service. Just wire it in to the Lucid key in a larger leather key fob case. The CR123...

I had previously disabled the Lucid feature that unlocks the car when the key is near. Also, measurement # 1 was taken very far from the car. The current shown was caused by a feature of the key itself. I'm thinking about either a higher capacity battery or a switch in the case.

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...

I measured the battery voltage with a high impeadance Voltmeter, after it failed at 2 months, as 2.7 V. (VS 3.3 V for a new battery) Bitterent should have nothing to do with this, UNLESS it is across the terminals causing additional drain. We need to measure the residual current drain by the...

2025 Air Pure 2 months old. 600 miles. I went into my garage today and pushed door handle to open car - Nothing! 100% dead. I was in a rush so had to borrow wife's Lexus. Upon digging, I found my non-working key fob CR2032 battery was at 2.7 V and the other working keyfob was at 3.0 V. I...
