How do I use the keyguard to prevent keys from being accidentally pressed on my Nokia phone?
To prevent accidental keypresses, select Menu, and press * within 3.5 seconds to lock the keypad. To unlock the keypad, select Unlock, and press * within 1.5 seconds. If Security keyguard is set to On, enter the security code if requested. To answer a call when the keyguard is on, press the call key. When you end or decline the call, the keypad automatically locks. When the keyguard is on, calls still may be possible to the official emergency number programmed into your device.
