Theodoor automatically unlatches, opens, and closes residential swing doors. It installs in minutes without any home modifications.
Aging in place breaks at the front door. For millions of people with mobility challenges, something as simple as opening a door means waiting for someone else to help, or paying thousands for a permanent door opener installation. Our portable product installs in 5 minutes, giving people independence and the ability to fully access their home.
No drilling. No electrician. No door or frame modifications. DIY installation within minutes.
Works with compatible wood, glass, or metal residential doors. No special frames or retrofits required.
Activate with a Bluetooth key fob or Theodoor app (no Wi-Fi required). With Wi-Fi works with Alexa. Automatically stops when encountering an obstacle.
When not in use, the system disengages completely so the door feels like a normal door. No drag. No added force.

Install with 3 steps within minutes
Theodoor sticks or screws to the door base & the latch attachment connects using existing door screws.
Connect the cable from the latch to Theodoor & route the power wire along a wall and plug into a standard outlet.
Bluetooth pair with a key fob or Theodoor app. Also can connect to Wi-Fi for Amazon Alexa and smart home hubs.
Theodoor is designed for most residential swing doors. However it still might work on some commercial doors. We are in development of systems that unlatch any door. To see if our current system works fill out this form.
Yes. Keep using your existing manual deadbolt, and unlock it before activating Theodoor. The current system operates the door latch and moves the door; it does not operate the deadbolt.
Alexa is available as an optional beta add-on for customers who have Wi-Fi and want to test it. Standard operation uses the two included Bluetooth buttons and does not require Wi-Fi.
We'll keep you updated about early access units and full product launch
Our mission is to remove barriers in the home. Theodoor attaches to a compatible residential swing door and helps people open it without waiting for help, without drilling, rewiring, or modifying the home.
