I do not believe that once microcontroller's lock bits are set, any data can be read from it further. I use SinaProg software to set lock bits; may be the reverse could also be possible using the same software, try it out. Once the lock bits are cleared, you just need to read the flash memory and then you could generate a hex file.
Do tell me if it works
