Mobile Key no longer recognized / detected - can't lock car with mobile key or by pushing in handle on door

[Demosthenes]

Except for two times for valets, I have not carried the fob with me for over a year. Mobile Key, at least on the iPhone, works very well.

Sounds like it’s working well for some, but not so well for others and no clear answer as to exactly why that is . But regardless of what the concerns are at this time, I’m definitely going to move back to mobile key only as soon as I possibly can because I very much preferred that (it happened to work very well for me too). And if it so happens that it takes 100-300 seconds to get into my car from time to time, I hope and trust that I’ll greet such events with a wry smile on my face, like an old friend

I suspect some of us might have differing expectations when we talk about how reliable the mobile key is, but would be happy to hear otherwise, so I'll be more specific.

Mine always works... eventually. It almost always works quickly if I actually take out my phone and wake it (my iPhone 15 PM) up. I'm assuming it's the iPhone's job to signal the car, and iOS power saving just doesn't think it needs to do that very often when it's in my pocket.

I almost never have to actually open the Lucid app to unlock the car, but that definitely happens sometimes. I don't think I've ever had this issue getting into my car for the first time in the morning, but if I have to make multiple trips to load things into my car, the second or third time it will often sit there with the handle depressed making uncertain car noises as it ponders whether to let me back in or not. I've taken to leaving a door cracked open if I'm just stepping away for a moment. One time that also turned out poorly, as the car decided to lock anyway (all except the open door, which I've never seen before), and then sounded the break-in alarm when I opened the cracked door again.

I never have to enter a pin to drive with the mobile key, and I have only seen the "no key detected" message once or twice in the months since I stopped carrying the fob in addition to the mobile key.

Note - I have automatic unlocking off, automatic locking on. Like many, I'd turn automatic unlocking back on and probably have a better time if it could be geofenced to avoid constant unlocking at home.

It amazes me the gyrations some go through to get the mobile key working. The fob is so light and so small, I have no idea it’s in my pocket…and it works every time in just the manner you expect. Used with the right battery, it should last 6-12 months. Proactively replacing the battery once or twice a year is, IMO, a small price to pay for reliability & peace of mind…but that’s me.

YES. FOB 4 life

It's likely I did myself a disservice by trying to use both for the first month or so with my car. That was absolutely worse than sticking to just the mobile key. I asked when I picked up the car and the Lucid SA said that shouldn't be an issue, but clearly that's less than true. Maybe at some point I'll try removing the mobile key and using only the fob.

One or the other is definitely the way to go. My testing with the iPhone is that it's slightly more reliable that the Android Mobile Key in that with the iPhone I can take the phone out and shake it and that will trigger the mobile key to open vs Android needing to unlock the phone and open the app. This is only for the first drive of the day however. Subsequent openings work the same.

My iPhone mobile key stopped working after the latest iOS update (as did my hearing aid app's ability to control the aids), so I suspect there was some Bluetooth issue with Apple's update. I deleted the mobile key and then re-paired, and it seems to be working OK now.

I have not carried it for well over a year as well. In fact, I had to put the key card in my wallet because I realized that I had no way for the last valet to take my car lol - luckily he let me self-valet that once, but from that point I now carry the card.

Correct. You don’t even have to wake it - just move it. I sometimes just walk with great swagger lol - if you trigger the accelerometers, it will also begin transmitting.

I have no other keys. Front right pocket is wallet, left pocket is phone and chapstick.

My butt pocket don’t have stuff in them anymore due to the way my wallet affected my back.

But yeah, no other keys - house is electronic, and no office to go to at the moment. If I end up needing an office fob, I may carry the car fob again.

For me, I carry all three all the time (Fob, Key Card in my wallet, and mobile key). Probably due to the fact I my profession is in technology, and so always have two backup plans

Same. I have all three almost at all times. Never caused an issue for me.

Mobile key and key card for the win.

Gotta say having to jiggle the iPhone to get mobile key to recognize is more annoying than carrying a fob

I might soon be able to divest all my physical keys once again and go back to just carrying mobile key so I’m following this thread with keen interest.

That this thread is still relevant is telling.

For those of you who are mobile key exclusive; what is your process for opening the frunk? Is it different when you have a cart full of stuff to load on a rainy day?

You just demonstrated why I still carry the fob. There is no other good way to open the frunk reliably.

Is there a feature somewhere to see what the fob battery level is? I had a case recently where I gave the fob to a mobile detailer and the weak fob battery locked him out of the car. (FWIW, I had put a fresh battery in 3 weeks prior and there was no warning from the car that it was low.)

Unfortunately, no.

I have accepted that the mobile key is hit or miss when I push the door handle to unlock. I thought it was a bluetooth connection but I'm beginning to rethink that. When parked in my garage with strong wifi, it always works. When I'm at the store, it seldom works and I have to wake the phone to get it to open. re: trunk - I have to unlock the car first to get the trunk to unlock. I'm disappointed the trunk button doesn't work to unlock at least the trunk. In inclement weather, I'm standing out there trying to get the car unlocked so I can put stuff in the trunk - PITA.

Mobile key does not use WiFi.
It does suck to have to walk around to the side of the car to get the doors to unlock in order to use the trunk. I also consider it a safety issue that I must unlock all doors and can’t select to unlock the driver’s door only.
