Depends on the lock being actuated and the torque of the servo, I have some that can do 4.4 N-m.

A stepper motor would also work for sure.

If you have some electronic skill you can use espHome on a esp32 microcontroller to control an RC Servo motor.

If you want out-of-box there are several electronic locks that will work.
