Questions people actually ask.

No. The link opens in whatever browser they already have, and the car controls work from there. We recommend the Tesla app because it works without signal, but nobody is forced through it.

The key stops working on its own — you don't have to remember to revoke anything. If they set up the Tesla app, that access is removed too, and the car leaves their app.

If they're still driving toward the drop-off when the window closes, we extend it rather than mark them late, and tell both of you what changed.

We hold their name, their phone number and how the car was driven during the trip. It's held under our retention policy and we don't sell it. They're told all of this before they agree to anything. See the privacy policy.

Model 3, Model Y, Model Y L, Model S, Model X and Cybertruck. Some features depend on the car's software version — Guest Mode needs 2024.14 or newer, and we tell you when a car is too old rather than hiding the option.

No, and no third-party app can — Tesla blocks it at firmware level. The closest is Tesla's own app, which HostKey can pair to the car for the trip. We walk your guest through it and recommend it for exactly this reason.

The link needs signal at both ends, so it may not reach the car. The Tesla app works over Bluetooth and will. If the guest has neither, the key card is the fallback — which is why we ask about it before letting anyone skip setup.

Yes, per car. Tesla's own minimum is 50 mph — if you ask for less we tell you rather than silently setting something else. Valet mode caps at 70 and overrides a higher limit, and we say that on the screen too.

They can still finish — stranding someone at the curb over 12% helps nobody, and an abandoned unlocked car is worse for you. It's recorded, they're told you'll see it, and whether you charge for it is between you and them.

No. HostKey is an independent tool for people who own Teslas and rent them out. Tesla and the model names are their trademarks.
