I am not sure "deadbolt" is the correct term for what I am looking for. I am searching for the metal piece on the side of doors that extends to lock it, but one that can be controlled electronically (with Arduino).

The thing on the right of this video is exactly what I want, but I can't seem to find anything like it.

Does anyone know where I could find one of these, or at least what this would be called?

I am also open to other setups to lock a door, but the part I described above is preferable. It doesn't need to be very secure or anything; I mostly just want to make use of an RFID scanner.


I accidentally found the answer to my own question. What I am looking for suddenly happened to appear in my Amazon recommendations (even though I haven't searched for anything like this on Amazon), and found you can find a lot of electric door locks by searching "open frame type solenoid" including this one, for example.


You might have the most success with installing an actual non-electronic deadbolt bought at a hardware store such as Home Depot (if one is not already installed), such as in this video: https://www.youtube.com/watch?v=2vmOj4DII8I

And then hooking up a servo motor controlled by an arduino (or similar) attached an RFID scanner to lock and unlock the deadbolt. One possible bonus is that your servo and arduino + RFID setup will be portable to other doors. One retail example is the Kevo Convert by Kwikset, https://www.youtube.com/watch?v=7YY0_IrvXGE

  • I already found what I was looking for, however this may be a better solution. This is especially because if I lose power on the electronic one it will immediately lock (they need power to retract the deadlock and I don't know if I constantly want to rely on my setup being on and working).

  • Any ideas on how this setup would work specifically? Aside from installing the regular deadlock what would be the best method to control it with a servo? (ex. Use some sort of string or other material to pull the knob with the servo or modify the deadlock in some way?)
