try this code for samsung phones... *2767*2878# -> Custom EEEPROM Reset i believe you have to take the sim card out and enter the code as shown and it will reset the phone and wipe the password Good luck

Yes that's possible with every phone just go on settings, security phone settings on automatic key-gard(keyboard) and turn it off. But before you need to know the code for locking and unlocking like in all nokia is green button and *.Not sure for samsung.
Good luck!
