    Default Security Master Code For DCT-3 and DCT-4 phones.

    All the users who have forgotten their Security/Lock Codes need not worry. You just need to know your IMEI (International Mobile Equipment Identity) number.

    To check your IMEI number, type *#06# on the main screen. This number can also be found on the backside of the handset. Just remove the battery.

    You can visit a site which will calculate the Master Code of your phone. This code can be used to change your present Lock/Security code.

    Nokia Lock Code


    Note :
    1. Lock/Security Code is not the PIN Code.
    2. If you want to remove the Service Provider Lock, then this is not what you are looking for.
    3. The Master Codes are only for DCT-3 and DCT-4 phones.


    Check this list if you are not sure if your phone is DCT-3 or DCT-4

    Nokia DCT Check List

    "Remember This is for DCT-3 & DCT-4 Nokia phones only it will not work on DCT-5 or BB5 Models."

    Also neither i, nor Mobiles24, can guarantee 100% accuracy.

    You type it into your phone when turning it on, your phone will ask for the security code and you then enter it, you can then go into settings and security and change it to something that is easier for you to remember if you wish.

    Your Phone is a BB5 phone. i suggest you contact your service provider to see if they can offer you any assistance or take it to your local Mobile Phone Dealer and get an engineer to sort the problem, this code only works on DCT - 3/4 phones.

    Always a good point to try and use Security Codes that you are not going to forget, saves a lot of trouble and expense in some cases.


    Found a tutorial claiming to unlock BB5 phones, you can read it here;
