Recently i faced an issue with my old Nokia 1650 phone. Since i was using it after 4 years, i could not remember its pass-code or security code. It was really urgent for me to open it, so i started searching hacks on google. May steps were given but best was below. It worked for me really.
- Switch on your device. It will show a rectangle box to enter security passcode
- Next press and hold * key + 3 key + Call button + Power button.

- Now your phone will switch off. Switch it on again
- Now in Security passcode box, enter 12345.
- It will work 🙂
