Labor Day App Outage Left Some Tesla Drivers Locked Out

Just because you can unlock your electric car with an app doesn't mean you shouldn't carry a physical key fob or card. You might end up like these temporarily stranded Tesla drivers.

Some Tesla owners reported being locked out of their vehicles on Monday evening because the electric car's app was down. The problem is, app connectivity shouldn't have any effect on unlocking a Tesla.

On Monday, numerous drivers found their apps were down "for maintenance" and they were locked out of their vehicles, some for several hours. Tesla allows owners to unlock their cars both using a physical key card or fob, and virtually through their smartphones and the Tesla app. Even with the Tesla app down, the user's smartphone itself is designed to act as a key as long as it's in Bluetooth range of the vehicle.

The caveat here is that this phone-as-key function is only available for the Tesla Model 3, not the Tesla Model X or Model S. So even if Model 3 drivers left their key fobs and keycards at home, and their Tesla apps weren't fully functional, Tesla vehicles should still unlock once a driver's Bluetooth Low Energy (BTLE)-paired smartphone is in range of the car.

A Tesla spokesperson confirmed to PCMag that the mobile app was briefly unavailable starting around 4 p.m. PST on Monday, but that full functionality was restored soon after. During the outage, a number of drivers took to Twitter to voice their frustration:

Numerous other Tesla owners responded that despite the app outage, their key fobs, cards, and Bluetooth connectivity were working fine. The Model 3's phone-as-key function works separately from the in-app lock and unlock feature, which does require cellular connectivity and would be affected by an app outage.

There are a couple reasons why some users were locked out while others weren't. Some Tesla drivers were logged out of their apps around the time of the outage, and couldn't log back in due to the app server outage. Others, who drive a Model S or X as opposed to a Model 3, don't have phone-as-key functionality. If they were without a physical fob or keycard and couldn't log into their apps, they were out of luck.

Tesla tells PCMag that the Model 3's phone-as-key feature was not impacted by the mobile app outage for users who stayed logged into their accounts. The company encourages all Tesla owners to carry physical keys with them, just in case.
