Resolved Question: Help! I've managed to stuff up the security keypad lock code (not the power on access PIN) on my Nokia N95....
...I've only just got it, and went to change the keyguard lock code from the default '12345' to another number, but it appears I've done something daft, as the keypad isn't locking using the security code (thank goodness) and when I went into the security settings to see why, it keeps saying "code error". Does anyone know how I can reset the security codes to the factory settings? Thanks..... : (

Resolved Question: Remove home security keypad and plater over wires?
Hi, I have just moved into a new house and want to remove the ADT keypad display thing, and also the alarm, from the wall before I begin to paint.
