You can't. The key is simple but you need a key. You local supplier probably has spare keys. It does not appear to be a mainstream company here in North America.
It keeps freezing because you have a bad program or a virus in it. The easiest way to fix that is to reinstall windows - just put in the recovery cd, select it from the boot order (the key to press for that is in the first screen that appears when you turn the laptop on) and follow the instructions.
This happens when a startup program is is corrupt or is not responding.It can also be that a hardware is gone corrupt that is making the computer freeze.To correct the problem please follow the trobleshooting steps listed below.
Disconnet any external devices that you have added after you bought the notebook like usb devices ,printer etc.Then turn the computer on and see if the computer freezes or not .If it does not freeze then it means that there is an external device that is causing the problem and to find it out you need to connect one device at a time and check .
U can also do this .Turn the computer off completely and then when you turn the computer on keep on tapping the F8 key till it loads the advance boot menu page then select safe mode just plain safe mode and hit the enter key .Wait till it loads the the log on screen then select administrator.It will take you to the desktop and check if the computer freezes or not .If it doesn't then it means that there is a program that is causing the computer to freeze.Go to start?run ?type in msconfig?enter?click on the startup tab ?click on disable all?apply ?select the services tab?click on disable all ?apply ?click on ok or close to exit from the page and then select restart when it prompts you to .When it is booting up to the normal mode check if the computer freezes.Then you will have to find the program that is causing the computer to freeze.To do this first enable all the startup program and then check if it doesnt then its a program under services that is corrupt .S o select one or more program restart and check so this way you will have to isolate the program and then just leave that program unchecked.
Hope this post helps you ...all the best
