I have done flashing with Arduino and St-Link v2, after completion nothing happened when I pressed the 1,2,3,4 button

It’s probably a good idea to use openocd to fully blank the chip and erase the write protect flags. I did this anyway since I was also trying to dump the firmware to back it up (and I do have a copy of that somewhere...not that that matters now)

I assume you’re using an ST-Link2?

Let me know how you get on!

Before flashing using Arduino and St-Link v2, I have done backup firmware of NRF-51 using "nrfsec read -a" with output backup files:

nrfsec unlock with result : Protect All Disabled

however i can't empty chip with command "nrf51 bulk_erase", i used "nrf51 mass_erase" command to erase chip on OpenOCD, is this the problem?

finally I uploaded OFO_Codelock.ino using Arduino v1.8.13 and ST-Link v2 with configuration:

And the result is : Sketch uses 3396 bytes (2%) of program storage space. Maximum is 151552 bytes.

I would try flashing a known sketch onto it and see if you can make the beeper beep to test it. These locks are particularly vulnerable to water ingress and it’s possible your buttons are somehow damaged
