Common questions

My car refuses every command. Nothing works.

Almost always this is the virtual key, and it is a one-time setup step rather than a fault.

Tesla requires you to add WristUnlock to your car as a key, in the same way you would add a phone key or a key card. Until you do, your Tesla refuses every command we send — lock, unlock, climate, charging, all of it — and it refuses them at the car, so there is nothing the app can do about it from its side.

How to add it, once, per car:

1. Open WristUnlock on your iPhone and tap Settings → Add Key to Your Car. (Setup offers the same step, headed “Add the key to your car”.)
2. That hands you to Tesla's own app, on Tesla's own approval screen. Approve WristUnlock there.
3. Come back to WristUnlock. Commands start working immediately — there is nothing to re-enter.

Two things worth knowing. You can remove the key at any time from your car's Locks screen in the Tesla app, which is how you revoke our access at the vehicle — so this is not strictly a one-time task, and commands failing again later usually means the key was removed. And a Tesla holds at most 20 keys; at the limit you have to delete one before another can be added.

If commands still fail after the key is on the car, email [email protected] with your car's model and year.

Why does unlocking ask me to hold the button?

Because it opens a two-tonne vehicle. A single tap is far too easy to trigger by brushing a sleeve, so commands that grant physical access need a sustained hold or a turn of the Digital Crown — deliberate in a way a stray tap is not. Lock, climate and charging stay single-tap; none of them can let anyone in.

Why does Siri ask for Face ID before unlocking?

Voice is the one channel where the phone cannot tell who is speaking. Without that check, anyone holding your locked phone could open your car by talking to it.

Why is my car's status a few minutes old?

Asking Tesla for fresh data can wake the car, which drains the battery and costs money every time. WristUnlock shows recent cached status and labels how old it is, then fetches live data when you ask. If it says “Asleep”, the car is sleeping on purpose and that is healthy.

Commands feel slow.

Every command in this release travels through the cloud, and that takes one to three seconds — longer if the car is asleep and has to wake up first, which is the usual explanation for a command that seems to hang for several seconds and then works.

A Bluetooth fast path that will land commands in about 300 ms when you are next to the car is planned and not yet built, so standing closer does not currently make anything quicker. If commands are consistently slower than about three seconds, tell us — include your car's model and year, and roughly when it happened, because command outcomes are logged and can be checked.

I'm not getting notifications.

Check three things in order: notifications are allowed for WristUnlock in iOS Settings; the specific alert is switched on in Settings → Notifications; and you are signed in. Sentry alerts additionally need Sentry Mode enabled in the car.

What does it cost?

Nothing. The first release is one free tier with every feature included — there is no paywall, and no in-app purchase of any kind in the app. A paid Pro tier is planned but is not available, so there is nothing to buy and nothing to cancel today. Its renewal, cancellation and refund rules are published in advance in the Terms of Use, so nothing about it will be a surprise when it does arrive.

How do I delete my data?

Settings → Delete My Data. It erases your data and revokes WristUnlock's access at Tesla, so the connection genuinely ends. The privacy policy lists exactly what is removed — and the one anonymous category that cannot be, with the reason.

Is my Tesla password stored?

No, and the app never sees it. Sign-in happens in Apple's own secure browser, which returns an access token without ever showing the app your credentials. That token is encrypted on the server.

Does it work without my iPhone nearby?

Yes for cloud commands, once set up. The initial sign-in has to happen on the iPhone — a watch is a poor place to type a password — and the watch receives what it needs from the phone afterwards.

Which vehicles are supported?

Any Tesla the Fleet API covers — and on every one of them you must first add WristUnlock as a key to the car (see the first question above). Status, alerts and analytics work without it; commands do not.

The planned Bluetooth fast path will be limited to vehicles that support Tesla's vehicle-command protocol — Model 3 and Model Y, and 2021-onward Model S and Model X — and it changes only how fast a command arrives, never whether it can be sent.

Is this made by Tesla?

No. WristUnlock is independent and is not endorsed by Tesla, Inc. It works through Tesla's official Fleet API using access you grant yourself. See Legal.

Something else

Email [email protected] with what you expected, what happened, and your car's model and year. If a command failed, roughly when it happened helps — there is a log of command outcomes that can be checked.
