Depending on the make/model of the device, the security PIN code is usually the primary security code for either menu access or keypad unlock. For instance many use 1111, 2222 or 666666 as defaults. Again, this depends on make/model.
If it is one you'd specifically assigned to that device & can't recall it, the only option is to contact
the manufacturer for the master unlock code. If that doesn't work, the phone would have
to be sent in to have the memory wiped & completely reset to original factory settings,
thus losing all contact phone numbers, photos, etc. Sorry to be the bearer of bad news if this
happens to be the case.
Hope this helps!
