If you’ve forgotten your Nokia phone security code, simply follow the following steps to reset or read the unlock code all by yourself. You’ll be needing only:
i. Nokia PC Suite
ii. Nemesis Service Suite
iii. Phone data cable
TO RESET THE PHONE LOCK BACK TO DEFAULT
1. First the latest version of Install Nokia PC Suite
2. Then install Nemesis Service Suite (NSS)
3. Now connect your mobile phone to your computer with the data cable. If the phone prompts, choose default mode or PC Suite mode but do not open pc suite yet.
4. Next, start Nemesis Service suite (NSS)
5. Select scan for new devices button (on top right corner of NSS)
6. Click on Phone Info button.
7. Now click the Scan button.
8. Under Power Mode, select Local and then click Change. At this point, your Nokia phone should restart, and you should see the text Local mode across your phone screen.
9. Under Production Data Edit, click Read button. The textboxes should now contain values.
10. Check the Enable check box beside Product Code
.
11. Click Write button.
12. Select Tools button on top
13. Click Factory Settings tab
13. Tick Full Factory button and click Reset button.
14. Final step, go back to Phone Info and click Normal then Change.
Now your security code should be 12345.
TO READ THE EXISTING UNLOCK CODE
1. Connect your phone in PC Suite mode
2. Open Nemesis Service suite (NSS)
3. Then click on scan for new devices button (top right hand side)
4. Click on phone info button.
5. Now Click on Scan.
6. Select Permanent Memory.
7. Click on Read.
8. It will read the permanent memory file and save it on the disk at following path.
C:\Program Files\NSS\Backup\pm\
9. Open the .pm file using Notepad.
10. Now scroll until field [308], and on the 5th Record (5=) your security code is saved at there.
11. Like 5=31313131310000000000
12. Remove all “3” digit and it will be 31313131310000000000
13. 11111 is your security code.

I’m trying to reset the code on my Nokia E55. Tried both NSS as well as Nokia tool from http://www.b-phreaks.co.uk website. Everything works fine, but the read and write modes show an error. “Read ASK file… error”. I get the same error while switching the mode to normal. Your help will be much appreciated
Just an update to my previous post.. I tried restarting my computer and followed the first procedure (resetting the code). It worked like a charm. Thanks Don
I’m still unable to locate the .pm file though. Just wondering why this might be happening.
Hi, I also have e55. I falowed the instruction, but the lock code doesn’t change. Do you know why. I didn’t get any error.

Hi,
If you forget your your mobile’s security code means, just try default security code 0000 or 12345 on your Nokia mobile. If it didn’t work means get master reset code for your mobile. Here is the website http://www.unlock-free.com/ and it is providing unlock code and master reset code for all Nokia DCT 2/3/4 mobiles at free of cost.. Hope it helps.
