Want to reset security access code on my Nokia

Don't worry you can reset the Nokia 1600 from the security lock using the master reset code,you can get the master reset code from here
Simpleunlocking.com and reset it.......simply as the website name the master reset also easy.

for giving security code you need to go to service provider(airtel,aircel,vodafone...) office or nokia ...
they only set the security codes..
if YOU set the codes,the sim card will be blocked and you cannot do anything,so better move service provider office to set the security code..
"DONT FORGET TO RATE'

Hi if you give me the imei number off the back of the phone under the battery once i have this i can then get you the master security code witch will then give you access to your phone and reset the security code to what it was when the phone was new.

If how ever the wrong code has been entered more than 5 times then this means the phone is hard locked and can only be unlocked using leads and software this can only be done at a phone shop and they will charge for this service.

Let me know then i can assist you further

What do you mean by 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?
Special Code/Service Provider Lock Code:
This code is required to allow a phone locked to a particular network's SIM cards to be used with a SIM card from another network. Orange and T-mobile lock handsets in this way, though O2 and Vodafone are beginning to lock PAYG and WAP handsets. The unlock code varies from individual handset to handset.
Blacklisting:
This is not a security code, but it works like one! To help combat mobile phone thefts, the networks share a database of the IMEI (International Mobile Equipment Identity) of mobile phones that have been reported stolen. Once a phone is on this list, it will not be allowed to use any of the networks.
This can be a risk if you buy a second-hand phone, because if it has been stolen, or if an unscrupulous seller makes an insurance claim after selling, the phone you bought in good faith may be permanently disabled.
Be very careful to check the source of a second-hand phone!
-----------------------------
The default security code for Nokia is 12345
IMEI: 356406017443168
Master code: 5335036136
Take your SIM card out first.
This is the code needed to reset the Security code, nothing else, and it’s for your phone only. You type in the security codes (anything) until the phone request the Master code; when it does, leave your phone still, don’t use it for 15 minutes, then type in the Master code.

356406017443168
master code:
5335036136
356406014836323
master code:
7151635151
for the rest just post your IMEI number, for your master code

Turn off your phone, remove the battery, take out the sim card, than put it in a bag and throw it away.Let me know if this was helpful
