Xseries :: Nokia X3 02 Turning Off 'unlock' Option

I can't seem to turn off the "unlock" option on my Nokia X3 -02 phone.A few people have suggested changing my security settings, but that's not the problem. Every few minutes the phone locks automatically, then I have to slide the unlock option to get the phone operational.Isn't there any way to override this "lock". It's completely automatic, and very very annoying to have to unlock the phone every time I want to use it. I realize the lock is there to protect unwanted use, but I'd rather be responsible for that and not have the phone decide when to lock.
