Thank you, but it asked me to enter 4 pin to unlock

Please try nvRAM reset:

1. Power off your Mac.
2. Press your Mac’s power button and then hold these four keys at the same time: ⌘ + option + P + R.
3. Continue holding the keys until your Mac restarts for the second time. On older Macs, the chime will sound upon restart. On newer Macs, the Apple logo will appear and then disappear.
