It can be a pain when buttons on your Sony Ericsson W880i get pressed when in your pocket or bag. You can force your W880i to lock the keypad by pressing * then Lock keys or you can set it to automatically lock after a short time.

1. Enter the main menu by pressing the centre button, then select Settings (Figure 1)
2. Scroll down and select Security (Figure 2)
3. Highlight and select Automatic keylock (Figure 3). Then select On to activate it (Figure 4)

For added security, you can set your phone to lock with a numerical code. This means that if you should lose your phone, it will require a passcode to be switched on again.

You have three options: On, Automatic and Off. 'On' means that you will be required to enter the passcode every time the phone is switched on, whereas ‘Automatic’ will only require a password if the SIM is changed.

To activate any of these functions:

1. Hit the centre button to enter the main menu, then select Settings
2. In the Settings menu click on Security
3. In the Security menu select Locks (Figure 5)
4. Then choose Phone Protection (Figure 6) and Protection
5. Choose the protection level by selecting from On, Automatic and Off (Figure 7)
6. You’ll be required to enter your passcode to continue (Figure 8), then you’ll see a confirmation message
