Sony Vaio PCG and some Vaio VGN Series use the last 7 digits of the laptop serial number to calculate the bios master password. The serial number for a Sony Vaio is often located on the bottom of the laptop on a white sticker. The serial number may also be found by removing the battery and checking in the battery compartment. The link to unlockbiosrecovery.com below works on the following models:
PCG-C, PCG-F, PCG-GR, PCG-GRS, PCG-GRT, PCG-GRV, PCG-GRX, PCG-GRZ, PCG-N, PCG-NV205, PCG-QR, PCG-R, PCG-SR, PCG-SRX, PCG-TR, PCG-V, PCG-VX, PCG-X, PCG-Z, VGN-B, VGN-FS, VGN-S, VGN-T, VGN-TX1, VGN-X

For $20 they use the last 7 digits of the laptop serial number to calculate the bios master password and then email it to you in an hour. They guarantee it to work and you can call them if you have a question.

Not sure which key Sony used but the easiest way to reset the Bios for a laptop is to start teh computer and go straight to Bios and select to restore Default settings. All Bios setups ahve this option. It is normally the F2, Del, F10 or F12 key right after you see the initial splash screen after tuning the computer on. The only other option I can think of without tearing the system open would be to remove the power cord, the main battery and the Bios battery if you have access then put it all back. In some models you can remove teh covers from the hard drive or Ram on the bottom of the computer and get to the Bios battery to remove it. I know a lot of HP models have that so it may be an option with the Vaio.
