Is it standard practice to carry around the keycard? Most owners I know don't bother. So this could potentially strand them unexpectedly but I suppose that's the same for any other car if you lose your keys (but at least not losing your physical keys is in your control).

I personally carry my key card at all times. It's the size of a credit card in my wallet so it's no bother. Regardless of how good their network services could be, I would never want to depend only on my cell phone to drive. You know, the thing I own that's most likely of all things to run out of battery, break, get stolen, be out of service range. All things that would strand me.

I can't speak for every owner and I'm sure some don't, but I certainly carry my key card in my wallet 100% of the time. It just makes sense; what if your phone dies? You are already required to have your driver's license while driving, so it's not like you can avoid carrying cards around, and carrying one more card is not as much of a burden as a giant key fob.

Yeah, they're credit card sized so I usually carry one in my wallet. Mostly to give to a valet if I need it. Some people have melted them down into fun key chain fogs. My gf has it as a ring.

I am a fan of a minimal wallet. I don't carry stuff I can do with my phone.

The card is a millimeter thick. It will fit in a minimalist wallet.

You can say that about 20 different cards individually and suddenly your minimal wallet isn't very minimal anymore

But since Tesla's app can spontaneously stop working, might be worth sucking it up and carrying the card anyway

For sure, IDK if my dad broke me, but I always try to have a backup for everything. Keys included.

[twiceaday]

Two is one and one is none!

[brokenmachine]

Your dad fixed you and is smart.

[polishdude20]

Wait.. people melt the cards down into shapes? And they still work?

[xeromal]

Yeah, you dissolve the plastic in a solution then take the antenna and form it into the shape you want.
