Another Model 3 owner was able to unlock mine

You still need to be within a couple of feet from the car to unlock it. I can be connected to my car from 30 ft away with my phone showing "Phone Key: Connected" but someone cannot open the car if the phone is that far away. Before posting I reconfirmed this by leaving my phone on the 3rd floor (still showing as Connected) and tried to open the locked car in the garage to no avail.
Irrelevant, the car COMMUNICATE via bluetooth, even if the address is the same, the phone need to reply with some sort of token to grant you access, so it doesn't matter, you simply can't have another phone unless he has the app opened WITH YOUR LOGIN!Pretty sure you are missing like four 0s on that number

I confirm. I just tried it.

Phone key may show connected, but the car has a number of radios to determine how far away you are and allow unlock. This is very easy to test.
The most likely situations:
1) door was not fully closed when he exited
2) used key card to unlock car, didnt lock when walking away
3) trunk or frunk slightly ajar
The chances of keycards having the same 'code' is next to impossible.

Yeah so just because the car locked doesn't mean you're out of range. Even after the car locks, if you're close to the car and someone to tries to open the door, it's going to unlock and open. And it could be like other people said, maybe something wasn't completely closed and it never locked in the first place.

Kind of related, When I press the charge button on the cable, my other model 3's charge port opens as well... Is that just a bug? I have never figured out why both car's charge ports open.

That makes sense. It would be hard for the cars to differentiate which one should open
I wouldn't rule out a SW glitch as in this case it seems likely that the phone was still connected, but far away. So I think there is a possibility that something went wrong with the proximity detection code.
But, it would still be less likely than those 3 things.
I tend to be a bit OCD about my car locking, and I haven't had any case of my car not being locked except for #2. That used to happen a lot at Valets, but hasn't been happening recently. I think Tesla changed the coding of it, but I haven't had a chance to test it.
A similar thing happened to me when picking my son up from soccer practice in May of 2019. There was a Dad and his son getting out of my car when we walked up. He was surprised to find it wasn't his car as his was 4-6 spots down. We were both needing to go so we didn't do any additional testing as I now wish we had. I have walk away locking and the fields we were walking from were 100+ yards away. I do have pin to drive enabled since I am in IT and understand every layer of security helps. It was definitely strange and concerning.
This. To stop a phone from working as a key, all you have to do is delete the app, not remove the bluetooth connection. At least on iOS (all I have to test), deleting the app does not remove the bluetooth connections but the phone key stops working. So in the very unlikely event that "the wires got crossed" with the bluetooth connection (which didn't happen) the wrong phone still wouldn't work as a key.
Since it sounds like this other Model 3 owner works in your building ; I would wait by their car for them one day and talk to them, ask them to test someday and see if what happened can be replicated. I am sure as an owner of the identical car would be curious as well and might be someone good to know.
My first thought was to dismiss this as I know for a fact, as others said, that Connected status does not mean the door opens. You have to be really close to it.
However, you and OP have similar stories. Two separate owners parked close to each other, and both owners in range to be connected to their cars via phone keys. Can one of the owners walk up to either car and unlock it? It would be an interesting experiment. If it doesn't work then your door probably just didn't close correctly or something.

The car does NOT rely on the Bluetooth ID for security. That would be ridiculously easy to clone. The car does a key exchange with the Tesla app installed on the phone. If you disable or force quit the Tesla app, then go to your car, you will be unable to unlock it until you relaunch the app.

You're right. I must have mis-counted when expanding out from my calculator's scientific notation. The point of it being a big enough number for an accidental duplication remains valid, though -- in fact, more so.
This happened to me on a couple occasions. It would be nice if the car would beep to let you know it was unable to lock.

In need of a shrinking gun to zap a plaid with.
I try to listen for the honk, but usually also look back at the car to make sure the mirrors are folded. Gotta agree though, it would be nice if the car would notify you (via the app would be simple I think).
You can see if it's locked in the app. But you have to open it. A nice feature would be to add an option for an app notification when the car locks.
