Terms

Last updated 2 October 2026

Who we are

Coil is an independent app, not made, sponsored or endorsed by Tesla, Inc. or Garmin Ltd. To reach us, email support@coilkey.com.

The Coil app

You buy Coil once in Garmin's Connect IQ Store. Garmin takes the payment, and Garmin's terms cover the purchase, including refunds. Buying it lets you use Coil, and its updates, on your own watches for your own cars.

Coil adds your watch as a key with your car's permission: the car accepts it only after you tap your key card and confirm on its screen. You can remove the key at any time, in the car under Controls, Locks, or in Coil's menu.

Coil Away

Coil Away is an optional plan that lets your watch reach your car through your phone's internet connection when you are away from it. Beside the car, Coil uses Bluetooth, which needs no plan.

• Plans and allowances. Each plan comes with a monthly allowance of commands, status refreshes and wake-ups, shown on the pricing page and on your watch. Allowances start again on the first day of each month (UTC). Unused allowance doesn't carry over.
• Paying. You pay by card through Stripe, monthly or yearly, in advance. Your plan renews automatically until you cancel.
• Cancelling. Cancel at any time on your account page, under Manage plan. Coil Away keeps working until the end of the period you have paid for, and you won't be charged again.
• Your right to change your mind. You can cancel within 14 days of first subscribing for a full refund. If you have used Coil Away in that time, we refund the part of the period you haven't used. Email us to ask.
• Price changes. We will tell you at least 30 days before a price changes. The new price applies from your next renewal, and you can cancel before then.
• What Coil Away depends on. Coil Away reaches your car through Tesla's Fleet API, your phone and Garmin Connect, which we don't control. We work to keep it running, but can't promise it will always be available, or that your car will always answer. If Tesla withdraws what Coil Away needs, we will refund the unused part of your plan.

Using Coil safely

• Coil can unlock your car and open it from a distance. Keep your watch locked with a passcode, and remove Coil's key from the car if you lose the watch.
• Check the car before you leave it: if Coil says it got no answer, the command may still have been carried out.
• Keep your key card or phone with you to drive. Don't use Coil while driving.
• Use Coil only with cars you are allowed to use, and only lawfully.

If something goes wrong

If Coil or Coil Away doesn't work as described, email us and we will put it right or refund you. We are responsible for loss or damage that is a foreseeable result of our breaking these terms or failing to use reasonable care and skill. We are not responsible for loss that wasn't foreseeable, for business losses, or for problems caused by Tesla, Garmin, your phone or your connection. Nothing in these terms limits our liability where the law doesn't allow it, such as for death or personal injury caused by our negligence, or for fraud.

Ending

You can delete your Coil Away account at any time on the account page, once your plan is cancelled. We may suspend a Coil Away account that is used to harm others or to overload the service, and will tell you why.

Changes and the law

We may update these terms, for example when Coil gains new features. We will tell Coil Away subscribers about any change that matters to them before it takes effect. These terms are governed by the law of England and Wales; if you live elsewhere in the UK or the EU, you keep the protections of your local law, and you can bring a claim in your local courts.
