Protect your device
Set your device to lock automatically
Want to protect your device against unauthorised use? Define a lock code, and set your
device to lock itself automatically when you're not using it.
1 Select Menu > Settings and Phone > Phone mgmt. > Security settings >
Phone and SIM card.
2 Select Lock code, and enter a lock code. A minimum of 4 characters is required, and
numbers, symbols, and upper and lower case letters can be used.
Keep the lock code secret and in a safe place separate from your device. If you forget
the lock code and your device is locked, your device will require service. Additional
charges may apply, and all the personal data in your device may be deleted. For
more information, contact a Nokia Care point or your device dealer.
3 Select Phone autolock period, and define the length of time after which the device
is locked automatically.

In the home screen, press , select Lock phone, and enter the lock code.
Unlock your device
Slide the lock switch, enter the lock code, and select OK.
If the lock switch is out of reach, press the menu key, and select Unlock.
