FREE Nokia Security Master Code Calculator

Have you forgotten your Nokia security code? Were you even aware that your Nokia had a set security code that may stop you accessing certain features or basic functions, such as changing network providers for use with a new sim only or pay as you go sim card?

The following guide has been written to help you reset that mysterious security code, without the need for complicated procedures or cables. Best of all, it's completely free and can be done online without the need to download additional software with our Nokia Security Master Code Calculator.

What is a Nokia Security Code?

A Nokia security code is a five digit pin code that allows you to protect your phone from unauthorised use. Every Nokia comes with a factory default security code of 12345. This default security code can be changed by you (infact its recommended that you do change it) in the advanced settings of your handest. Once you change the code, only you will be able access the protected features or functions of your handset, provided that you can actualy remember what you changed it to. Could be tricky if you set the security code several years ago.

Before we go any further, I’d like to point out that you only get three attempts at entering a Nokia security code. If you try an unsuccessful or incorrect code three times or more, your phone will become hard locked and you have to use a security master code calculator(instructions below), or take your phone to a Nokia service centre. I’m not responsible for this – you follow this advice at your own risk. If you feel uncomfortable carrying out any of the below procedures or using the master security code calculator, take your phone to your nearest authorised Nokia service centre who will reset the security code for you – for a fee of course. One other thing I would like to point out is that you must be the actual owner of the phone. This guide is not intended for use on handsets without the explicit authorisation of the owner. OK, so now that’s out of the way,

First step to reset Nokia security code:

The first thing you should try is the Nokia factory default security code, which is 12345. As described above, most Nokia’s have this default security codee. Unless you've changed it at some point, it’s likely that this is the code you need and you can stop here. Phew!

The Security Master Code:

If the factory default security code didn't work, the next thing you can try is what’s known as a security master code. A security master code is a ten digit number that can entered into your handset and will be accepted as if it were your actual security code. The security master code is calculated based on your handsets IMEI number.

What’s an IMEI number?

An IMEI number, or International Mobile Equipment identity number, is a number that uniquely identifies your handset. To obtain your IMEI number, remove the back cover and the battery from the phone; the IMEI number will be underneath the battery. It’s a 15 digits long number, just like the picture on the right. Dont forget to take a note of your IMEI number as you will need it in the next step. You can read more about IMEI’s at Wikipedia if you’re in to that sort of thing!

What phones are compatible with the security master code calculator?

Most Nokia’s released prior to 2005 are compatible. Here is a list of compatible phones; you should only calculate a master code if you have one of these models.

DCT3 Nokia models: 402, 2100, 3210, 3310, 3330, 3410, 5110, 5210, 5510, 6110, 6150, 6210, 6250, 6500, 7110, 8210, 8250, 8850, 8890, 9000, 9100, 9210.
DCT4 Nokia models: 3100, 3120, 3200, 3220, 3510, 3510i, 3650, 3660, 5100, 5140, 6020, 6021, 6070, 6080, 6100, 6101, 6103, 6170, 6220, 6230, 6260, 6310, 6310i, 6510, 6810, 6820, 6822, 7200, 7210, 7250, 7250i, 7260, 7270, 7280, 7360, 7600, 7610, 7650, 7700, 8310, 8800, 8910, 8910i

For a (non-definitive) list of incompatible phones, see the bottom of this article.

OK, my phone is compatible! How do I get and then enter a security master code?

Use our very own online master security code calculator at the top of the page.

Armed with your new security master code, when your phone requests a normal security code, simply enter the master security code instead. Your Nokia should now reset itself to the default security code, 12345. Easy as that.

I have a newer Nokia model, or the security master code didn’t work.
What can I do to remove my security code?

I’m afraid that you will have to take your phone to your nearest Nokia service centre or Nokia approved mobile repair shop. They can reset the security code for you, but you will be charged for this service! It’s is also likely that they will want to see your proof of purchase to prove that you actually own the phone. I hope you kept those receipts....

Incompatible phones:

As a rule of thumb, any Nokia released after 2006 won’t be compatible with a security master code. Here is a list of incompatible models. Please be aware that it’s not a definitive list. I don’t have the time to update it every time Nokia release a new phone!
