How to Measure Your Finger

Wrap a narrow strip of paper around the base of the finger on which you plan to wear the ring.
Make sure the paper fits comfortably and is not wrapped too tightly.
Mark the point where the paper overlaps.
Lay the paper flat and measure the marked length in millimeters.
Use the finger circumference column in the size chart to find your correct US size.

Important Sizing Tip: Please measure the exact finger you intend to use for unlocking your Tesla. If your measurement falls between two sizes, choose the larger size. If your knuckle is significantly larger than the base of your finger, measure both areas and choose a comfortable size between the two measurements.

Please confirm your size carefully before ordering. Each ring is custom-made according to the selected size, and an incorrectly selected size may not fit properly.

How to Use

Add the ring as a new key through your Tesla touchscreen using an authenticated Tesla key card.
Tap the ring against the driver-side B-pillar key card reader to lock or unlock the vehicle.
Place the ring over the designated center-console key card reader to authorize the vehicle before driving.
