hi
menu > settings > security > change lock code > apply master code in place of lock code and press ok > enter new code what you want

First you need to know if you have a standard 2700 or the new enhanced version, it makes a big difference. Press any 2 buttons then star, if you get no response it is a standard version, if it beeps several times it is the new version. If it is the standard version, disconnect the battery and press any button. Now you are at factory default. Reprogram the master code, remember the master code and the operating code must b e the same length. 12345 A 1 A new master code A new master code. The master code is the only code that needs to be entered twice during it's programming. To set a manager code press; master code A2A new manager code, to set a new user code; enter master code or manager code A11A new user code. The programming must be done during the lock's unlock window so write down the procedure you intend to use to make things go quicker, if you need more time you can change the unlock window, it is probably set at the factoy 5 seconds. Press master code A45A4, this will give you a 20 second window to program the lock, when you are finished change the lock back to 5 seconds, press; master code A45A1, keep the open window short to conserve batteries.

The only way to get around a parental lock is to put a new firmware on it or go to System Settings and reset the PSP to default settings. After the reset it will be 0-0-0-0.
