MATT3R K3YTM Review

April 25, 2025

If you’ve been looking for an add-on for your Tesla that detects incidents and captures footage from the built-in cameras, look no further than the MATT3R K3Y™.

The K3Y™ is a smarter alternative to a standard dashcam since your Tesla already has integrated video technology. It’s a discreet USB device that stays out of your way while tracking what you need.

What Does the K3Y™ Do?

The K3Y™ transforms how you access, store, and review dashcam footage by combining smart detection technology with seamless mobile integration. It automatically saves key moments to your private cloud, so you have total peace of mind in case something happens.

You will be able to seamlessly find the footage you are looking for without having to sort through endless folders looking for the clip you need. The USB device comes with a companion app—available for iPhone and Android users—that helps you quickly locate footage right from your smartphone.

Priced at $199, it does more than just record footage for you—it thinks. Using advanced algorithms, the K3Y™automatically tags a variety of events such as harsh braking, front-collision warnings, honks, FSD disengagements, and more.Within the app, you’ll be able to find flagged incidents with ease.

This device is not bulky like a regular dashcam. Instead, it is plugged into your glove box, so it’s out of your way and out of sight but still has full access to your Tesla’s built-in surround-view cameras (front, rear, left, and right).

The K3Y™ is currently compatible with the Tesla Model S (2021 and newer), Model 3, Model X (2021 and newer), Model Y, and Cybertruck.

Benefits and Added Features

With the help of the companion smartphone app, you’ve got cloud backups that automatically back up your essential footage to Google Drive or Dropbox, ensuring your videos are safe, even if your vehicle isn’t.

A feature that will allow for a cabin view is coming soon. What this means is that soon, it will have footage from inside the vehicle, furthering the coverage area. This is key for rideshare drivers with passengers.

With full coverage outside your vehicle (front, rear, left, and right), you’ll have more video coverage than a traditional dashcam, with the cabin view (inside coverage) coming soon.

Customer Thoughts on the K3Y™

The K3Y™ compares somewhat to the TeslaUSB, which has similar features but is more labor-intensive for the consumer.

With the TeslaUSB, you plug the USB device into the port in order to access the files of footage stored in the vehicle’s storage. It does not automatically upload anything for you; you have to actively hunt down each file you’re looking for, buried in layers of folders.

The K3Y™ allows you to remain hands-off, flagging those important incidents for you and uploading them to the cloud so you can access what you need within the app at any time with ease.

Something users love is that the K3Y™ has a GPS map and geolocation for events, so you know where you were when something happened and can use this for your personal information or for insurance purposes if needed. It’s also great that the cloud feature will automatically upload the video footage to your Dropbox or Google Drive account, whichever you’ve set it up for.

Users also enjoy that, unlike standard dashcams, there are no cords to worry about and clutter up your space. It stays plugged in and tucked away in the glove box.

Final Thoughts

If you’re looking for a smarter, more integrated dashcam experience for your Tesla, the K3Y™ is a powerful upgrade you can’t pass up. With intelligent tagging, cloud storage, and app-based convenience, it’s designed to make your life easier without adding anything to your dashboard or windshield.
