Description

Watt Key turns your Wear OS watch into a full Tesla key fob — no phone required.

Connects directly to your Tesla over Bluetooth. No internet, no cloud, no delay. Just your watch and your car.

RECENT UPDATE: Watt Key has been rewritten from the ground up for improved reliability and speed. If you tried Watt Key before and had issues, this is a great time to give it another shot.

FIND ON APPROACH
Your watch detects when you're near your Tesla and unlocks it automatically — before you reach for the door.

AUTO SECURE
Walk away and Watt Key locks your vehicle behind you. No fumbling with your phone.

FULL VEHICLE COMMANDS
• Lock / unlock
• Open any individual door
• Pop the frunk
• Open the trunk
• Toggle the charge port
• Open the Cybertruck tonneau cover

MULTIPLE VEHICLES
Own more than one Tesla? Name and switch between vehicles right from your watch.

CUSTOMISABLE TILE
Add a Wear OS tile for one-swipe access to the commands you use most.

BLUETOOTH ONLY — PRIVATE BY DESIGN
No account, no cloud setup, no internet required. Watt Key talks directly to your Tesla over Bluetooth — fast, private, and works even without signal.

WORKS WITH
Samsung Galaxy Watch and all Wear OS devices.

Download Watt Key and take control of your Tesla — right from your wrist.

v1.7

I love this app. I use it every time I go for a run. the new version looks great but has couple of issues. I'm not able to send the Vin number to the watch from my phone anymore and, I go through manual entering of the Vin number and it connects and works for a few days but then it forgets the Vin and I have to set it up again. Edit: when will the new fix come out? I haven't seen any updates since July.

Hi Pedram, there's a fix for this; open Google Play store app on your phone, go to Manage apps and device and you should be able to update Watt Key from there. It should update both the watch app and companion phone app. If you have any trouble email me at: joshendy89@gmail.com Thanks

v1.7

Similar issue with other users where it does not unlock automatically by approach even after extending the distances to max. Must open the app manually unlock. It would be good to know when it will be fixed and how to get the updated version. Other features seem to work fine. I m using Galaxy watch ultra2.

Developer Response

Hi Kevin, sorry about that. I've got a new version (11.5) releasing soon, just waiting for Google to approve it. I'll update this message when it's available. You can update the app by visiting the Watt Key page on Google Play by searching for it or going into manage apps and device in Google Play. Thanks. Update: v11.5 is now available

Despite the initial hiccups when trying to make a connection from Samsung Wartch9 to my model y, the app works as expected/described once I figured out how to follow the installation direction. Work great. Very reasonable price. Thanks.

v1.6

After a few attempts I was able to make it work. But to open the car you need to open the app o the watch.

Developer Response

Hi, I'm very sorry about the problems. I've recently remade Watt Key from the ground up. Could you please update the app and try again?
