About

Turn your Garmin watch into a Tesla key. The watch talks to the car over Bluetooth directly — no phone, no internet, no Tesla account. Free 24-hour trial after pairing. The licence follows the car, not the watch: US$6.99 for one car, US$9.99 for three. One-time purchase. After buying, enter that email in Connect IQ and tap Activate in the watch settings. Pairing and activation video (90 s): https://youtube.com/shorts/5yC8kxNHcJc Details and purchase: https://watch.homecmf.com/?p=keyfob What you can do from the watch · Walk-up unlock: keep the app open as you approach, then just pull the handle · Lock, unlock, and control all four doors independently · Open the frunk, the trunk and the charge port · Climate, Sentry mode, windows and charging — all over Bluetooth, no internet · Connects in 4-8 seconds; works from about ten metres away · Up to 3 vehicles, switched right on the watch How pairing works · Enter your VIN in the WatchKey settings in the Connect IQ app on your phone · Sit in the car and tap Pair on the watch · Hold your physical NFC key card on the reader and confirm on the car screen This is exactly how you add a phone key. The private key is generated on the watch and never leaves it. Before you buy · Connect IQ apps cannot run in the background, so you open the app as you walk to the car · Pairing needs your physical NFC key card — that is Tesla's requirement, not ours · A Tesla accepts only three Bluetooth connections at once; pause the phone key and Apple Watch while pairing · To revoke access, delete the key from the car's screen Compatibility · Cars: Model 3 and Model Y (all years); Model S and Model X from 2021. The car must support Bluetooth phone keys · Watches: 57 Garmin models across the Fenix, Forerunner, Epix, Venu and Instinct families · Interface languages: English, Traditional Chinese, Simplified Chinese Licence · One-time purchase, not a subscription · Tied to the VIN. Any number of watches can share the same vehicle · Changing watches costs nothing — just pair again Want remote control? WatchKey+ is the same app. Climate, Sentry, windows and charging work over Bluetooth in both — the difference is that WatchKey+ can also do them from home or the office, and adds charge limit and tyre pressure. Your licence covers both, so WatchKey owners do not need to buy again. Install only one: each app pairs separately and adds its own key to the car.

What's new

Version 2.0.6 - Main screen now uses icons for car controls, climate modes and the four doors - Fixed a crash when opening the settings menu on Venu X1 - Car controls now finish automatically once the car wakes, no second press needed - Pairing failures now show a diagnostic code to help with support Version 2.0.1 - Car controls can now be operated from a menu, no touchscreen needed (climate, charging, cable release, Sentry, windows, defrost, Climate Keeper, Dog Mode, Camp Mode) - Vehicle names now appear in the settings menu - Added German, French, Dutch, Norwegian and Swedish interfaces (8 languages in total) Version 2.0.0 WatchKey grows from a key into a remote. Alongside the existing lock functions, you can now control climate, charging and Sentry Mode straight from the watch - all over Bluetooth, with no internet, no phone and no Tesla account. New: Car Controls - Climate on/off and temperature - Start/stop charging, charge limit, release charge cable - Sentry Mode on/off - Windows vent/close - Climate Keeper, Dog Mode, Camp Mode, Defrost - Use the icon panel, or the menu if you prefer no touchscreen Disabled by default - enable it in the watch settings. With it off, the app looks and behaves exactly as before. Once enabled, open it from the top corners of the main screen or from the Car Controls menu in Settings. Please note Car controls use the vehicle's infotainment system, which is separate from the door locks. It sleeps when the car is idle, so the first command takes 15-20 seconds to wake it, and later commands still take a few seconds each. Locking and unlocking are unaffected and remain instant. Bluetooth performance varies considerably between watch models. Older or lower-powered models may connect more slowly, fail occasionally, or be unable to use this feature. Please test thoroughly during the 24-hour trial before purchasing. Other - Added German, French, Dutch, Norwegian and Swedish interfaces (8 languages in total) - Redesigned phone settings page: added a vehicle name field and clarified the VIN and password fields to avoid confusion - Removed support for Venu 2, Venu 2 Plus and Venu 2S (pairing could not be completed in testing)
