Because solenoid locks draw high currents (often up to 1A at 12V), . Trying to do so will almost certainly damage your microcontroller.
This indicates electrical noise or a voltage drop. Add a 100uF decoupling capacitor across the 12V power rails to smooth out voltage spikes.
Measure your physical solenoid lock. You will need a top-down image (for breadboard view) and a schematic symbol. Step 2: Use the Part Editor Open Fritzing.
If you cannot find a dedicated "solenoid lock" file immediately, you can use a functionally identical part in your Fritzing sketch. Mechanically and electrically, a solenoid lock behaves exactly like a standard or a generic Solenoid Valve . download solenoid door lock fritzing
Once you've downloaded a solenoid lock part file (typically with a .fzpz extension), follow these steps to import it into Fritzing.
Note: If you cannot find a specific graphic for the lock, you can use a generic "Solenoid" symbol in Schematic view or a generic 2-pin connector in Breadboard view.

Correct wiring diagrams prevent short circuits that can burn out your Arduino or solenoid.
Do not try to power the solenoid lock from the Arduino's 5V output. The Arduino voltage regulator cannot handle that much current, and the board will reset every time the lock triggers.
Connect the other end to the terminal of the relay. Add a 100uF decoupling capacitor across the 12V
Adafruit sells a standard 12V solenoid lock. Check the official Adafruit Fritzing Library GitHub repository. If a dedicated lock file isn't present, they provide a standard DC motor or generic solenoid file that uses the exact same two-pin terminal footprint.
This file was shared in a forum discussion for an electromagnetic lock and should serve as an excellent starting point.
