How do I set auto keypad lock?

[badboyblue]

Title says it all really.
Pissed off with ringing my contacts when the phone is in my pocket.
Can you set the keypad lock to engage automatically after a certain period.
Not talking about the "simlock" just the kedpad.
Been onto to Voda & called into a couple of shops - but no joy.
TIA

for autolck, go to menu then security then phone and sim and then autolock period, the only drawback is you need a pin to get back in , pain! i have it set at 11111 for speed , you can manually lock , top left button then star.

Yep I think thats the only option - seems you can download a "keypad autolock" but it get varying write ups.
