How can I bypass security code if I forgot it?

@obakengmosiane does not look like that you can do this without resetting it. That means you will lose all of your files etc. stored on the phone. I will reset to factory settings.

1. Remove the battery to power off the Phone.
2. Replace the battery (device should remain in off state).
3. Now hold down the “*”, “answer” key, “3", and the Power button all together
4. Keep all the buttons held in until it cycles past the Nokia Text Logo splash and hard resets the device,wait till done
5. You should now be past the Nokia animation screen and it should be asking for device info.
6. Reset all your device properties (time, location, etc) as prompted.

You can also find more information about that on here If nothing else give the 112 idea from here a try
