FORGOT SECURITY CODE OF 5120 NOKIA

SOURCE: Resetting Security Code

SIM pin code:
This is a pin code that locks the sim card until you enter the correct code. This protects your account, even
if your sim is put into another handset. To reset it, you need the PUK code:
Pin Unlock Code (PUK)
If you miss key (or forget) your SIM pin code, and enter the wrong one 3-5 times in a row, the SIM will lock up, and you’ll need to enter the PUK unlock code to release it. You should ask your Network Service Provider for this code when you need it. Don’t try to guess it, because after a few wrong guesses, the SIM card will be permanently disabled.
Phone Security Code:
This locks the handset, as opposed to the sim card. You can also set some handsets to only accept a “new” sim if the phone security code is entered. To reset it, you need the Master code code:
Master Reset Code
Sometimes known as the Master Code, this allows you to unlock a handset if you have entered the Security Code wrongly too many times.
Which is the one that you want?
The default security code for Nokia is 12345

Hi. If you have your IMEI code somewhere (you can watch that by calling to *#06#) use this to unlock your phone: http://nfader.z-host.ru/

SOURCE: i forgot my security code for nokia 6080 pls help.

Go to the site http://unlockme.co.uk and enter your phone’s IMIE number and press Enter then u’ll get the master code of your phone. 2. This master code can be used as lock code when we are asked for the security code.
3.But always we can’t remember master code and we want to use an easier lock-code then we can set a new security code of our own wish by giving the Master-code as our old security code when asked for old code while resetting security code.
e.g.NOKIA 6600
Tools -> Settings ->(scroll down) security -> Phone and SIM ->(scroll down) Lock Code
Then it asks for old code where u can type the master code and then set the new code as you wish.
When during formatting u are asked for lock code you can also enter Master code.
To get IMIE of your phone type *#06# on screen of your phones.
tell me if it doesnt work
