I have made the decision to acquire a Raspberry Pi 4 and embark on a project to develop a face ID door lock utilizing cv2 and related technologies. To facilitate this endeavor, I have procured a relay and a suitable lock. However, despite ensuring meticulous wiring, I am encountering an issue wherein the lock fails to open or close when attempting to supply power.
I have thoroughly verified the correctness of the wiring connections, eliminating any potential issues arising from that aspect. Nevertheless, I am uncertain whether the relay, the lock, or perhaps even the Raspberry Pi itself is the root cause of this predicament.
I would greatly appreciate any assistance from anyone willing to lend a hand in troubleshooting this issue.

Does your power source have enough current sourcing abilities for the lock? Sounds like a typical solenoid that will draw a huge current spike when you open or close it. Even if your wiring is correct, a lack of enough instantaneous power would cause the issue you are describing.

If he has diodes installed that shouldn't be an issue right?
As webdev said, are you certain you're supplying enough power? Would you be willing to post a video of what you have going on?

Certainly! I understand that I will need to reconnect all the components since I had stored them away, but it's not a significant inconvenience. I'm more than willing to do what it takes to resolve this situation.
In the interim, I have also acquired a keypad for a keycode door lock as an alternative to the face ID solution, considering its vulnerability. I believe it's a prudent choice to explore different options to ensure a robust and secure door lock system.

Diodes don't supply more power, they only act as protection devices for this application. Diodes would not solve the issue I am describing but could be used as protection to prevent transient spikes from back feeding the supply.

Ahh ya you're right I wasn't even thinking of the original issue.
