It was only a matter of time.

Thanks for posting. This method is nothing new though. The advice is the same as it has been for years with any kind of relay attack - faraday or disable passive entry and ensure you have p2d on. Passive entry and Bluetooth keys are a convenience feature not a safety feature.Just saw this - BLE phone-as-a-key vuln allows access to Tesla Model 3 so I guess BT is susceptible to relay attacks, I notice when you close the Tesla app the Tesla BT device disconnects on the iPhone so hopefully this is a workaround.
Keeping you phone in a faraday cage at home might be inconvenient.Thanks for posting. This method is nothing new though.

Not if the whole house is a faraday cageKeeping you phone in a faraday cage at home might be inconvenient.
I’m guessing they’ve made that up for the clicks. But I’m sure you already knew that!“electric car batteries” Now that is pretty impressive.
Well you’re the guy to find out! Tell us when you have carried out the experiments!My M3 has been having false alarms for the past 2 nights now (think there’s an insect, going to get it cleaned tomorrow) so I’ve been resorting to leaving it unlocked on my driveway after I stop the alarm.
1) how close does a phone key have to be in order to start the car? Is the car drivable between the period of exiting and it automatically locking?
2) if my phone key leaves the vacinity of the car whilst I’ve parked, will it still allow me to shift?
3) are both the above sceneries different if I primarily use the card key?
I just force close the app which kills the Bluetooth connection it has to one of the vehicle’s BT proximity sensors so it no longer can be used to open the vehicle until I launch the app again. I find the app noticeably drains my battery so I kill it anyway after I return home and won’t use the car again for a while.To benefit from this, you really want to disable your phone key, though. I don't really want to keep bluetooth on my phone disabled, so I just don't have my phone registered with my car as a key at all. I still have the app installed, of course. (This approach does have the downside that you can't remotely view the sentry cam, sadly, as that feature relies on the encryption keys that are set up when you enrol your phone as a phone key.) Obviously use PIN to drive as an additional protection, as it's impractical to ensure your fob is in a faraday cage at all times
So you won't get an alarm notification or something left open notification? I suppose if your car is within earshot and you are extra careful with checking before killing the app it's a solution for some.I just force close the app which kills the Bluetooth connection it has to one of the vehicle’s BT proximity sensors so it no longer can be used to open the vehicle until I launch the app again.

How confident are you that the phone won't restart the app in the background ?I just force close the app which kills the Bluetooth connection it has to one of the vehicle’s BT proximity sensors so it no longer can be used to open the vehicle until I launch the app again.

Tesla has FCC approval for a UWB module, but don't think it is implemented in any of their vehicles yet.Again, I would be happy to pay for an UWB upgrade if it was available
On iOS the app doesn't restart. I inadvertently test this all the time as I forget to launch the app and cannot open the doorHow confident are you that the phone won't restart the app in the background ?
Yes but some reports mentioned they would need to add a bunch of antennas to achieve precise location, so that would be for a new model/refresh rather than a simple module add/retrofit unfortunately.. I hope they're wrongTesla has FCC approval for a UWB module, but don't think it is implemented in any of their vehicles yet.
Apple managed to use it to locate a £25 AirTag, hopefully it isn’t too complicated.Yes but some reports mentioned they would need to add a bunch of antennas to achieve precise location, so that would be for a new model/refresh rather than a simple module add/retrofit unfortunately..

The vehicle already has multiple BLE sensors to triangulate your position - upgrade those to combined BLE / UWB and you can then detect if you are at the sides or rear of the vehicle with UWB.Yes but some reports mentioned they would need to add a bunch of antennas to achieve precise location, so that would be for a new model/refresh rather than a simple module add/retrofit unfortunately..
