How to Unlock Your Tesla Using NFC on Android Phones (Tap to Unlock)

We recently discussed a bunch of features that the Tesla Android App is missing in comparison to the Tesla iOS App, but we didn’t look at the other side.

If you’ve got an NFC-capable Android phone and a Tesla, you actually have a feature that’s not available on iPhones. You can tap your phone on Tesla’s NFC card reader to unlock or lock your car, just like you can with your keycard. Tap to Unlock is enabled by default on Android and cannot be turned off on NFC-capable phones unless you disable NFC in your system settings.

Tap to Unlock

Android provides Tesla with access to the API necessary for Tap to Unlock to function over Near-Field Communications (NFC). This means that the Tesla app can serve as a backup keycard if, for some reason, your Phone-as-a-Key (PAAK) doesn’t immediately unlock the car upon waking it.

You’ll need to be a bit precise with this, as most phones have a small NFC location near the center on the back of the phone. You’ll also want to place it slightly under the B-pillar camera, where the car’s NFC reader is.

When you’re successful, the car will honk twice and unlock. Of note, this will not load your pre-set profiles as if you’re unlocking using your phone key, as the car treats this as a unique key. You will not be able to set up Tap to Unlock to load a particular profile – it seems to load a “default” profile every time. This also means that if you’ve got your mirrors set to unfold or your seats to move back, this will also not happen.

However, once you hop in, you can select your profile and everything will adjust to you. Your phone will continue to work as a phone key to keep you authenticated so that you can start your car.

Unlock Car Even If Phone Battery is Drained

This feature serves as a convenient way to get your car open and unlocked if your phone won’t power on or if the car doesn’t recognize your phone key, which can sometimes happen. On newer Android phones, NFC remains on even if your phone battery has run out since NFC uses so little power.

If you disable Bluetooth on your phone or your phone battery is on empty, your phone key won’t work, so you’ll need to authenticate again inside the vehicle to start the car. You can place your phone on either the Wireless Charger (for newer vehicles) or in the NFC slot between the cup holders and the center armrest to authenticate.

Other NFC Devices

For those more adventurous, you can also use other NFC-capable devices as Tesla keycards. Personally, the author uses an NFC-capable ring, as well as a third-party app on an Android Watch as backups. They serve solely as backups in the case of a lost phone rather than my primary keys.

Tesla Says 12V Power Socket Access Will Not Return With Sentry Mode

By Karan Singh
Not a Tesla App

It turns out that the big undocumented change in Tesla update 2024.32 that disables the 12V power and USB ports while Sentry Mode is active is not a bug but an intentional change.

A fan contacted Tesla Service to see if the change was intentional and what the reason behind the change was. Surprisingly, they received a response pretty quickly.

No 12V Power Access

Tesla has decided to restrict 12V power access for safety reasons—namely, to “reduce the likelihood of thermal events” when third-party devices are left powered on without users present. Tesla reached out to the fan in question by phone, and they seemed to be sticking to that line.

It seems that Tesla is resolute that it was due to safety reasons and that the change would not be “fixed” or allowed in a future software update – as this was an intentional change for safety reasons.

Other sources have reported that the change was due to potential misuse of the 12V power access, with people wiring 1200w microwaves and kettles or jury-rigging 240v to 120v adapters, which had apparently been the cause of multiple fires in Tesla vehicles within China.

Workarounds

There are a couple workarounds, although neither are ideal. You can tap in to the vehicle’s 12v line directly to power your accessories, or you can use Camp Mode.

If you choose to enable Camp Mode, then you’ll need to manually lock the car from the app since walk-away door locking is disabled with Camp Mode. However, Camp Mode will use extra energy to keep the climate system enabled.

We’re still hoping Tesla considers bringing the Cybertruck’s Power Control menu to the rest of its vehicles and is somehow able to limit the max draw from these outlets to prevent dangerous situations.
