This code will reset any security code on your phone to one of your choice.

for 5300

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

357593006548708.........for this phone try resetting the phone or formatting by entring *#7870# for resetting and *#7370# for formatting in any of the case you should have your original number which is 12345 as the new code after resetting of formating but for formtting you would lose every contacts so you are advice to keep a copy of every important dorcument.

for nokia 5300 also try resetting or formatting to restore the usual pin code "12345" and to do this first copy all contacts and information need first even is restting it(which you do not lose any information) ........... to reset enter *#7870# and to formate enter *#7370# please try the first method before proceeding to the second one.
 
for nokia 3110c please this is your master code   6003104322
