Help w/ slide to unlock **PLEASE**

[jimmiekain]

I am running the new official sprint 6.5 rom. I have been trying for over two weeks to figure out how to get it to lock automatically whenever I turn it off. The magnetic latch on my belt clip turns it on as soon as i put it in. I really dont wanna use s2u2 and through fooling around w/ it i found that if i put a 4 digit numeric passcode on it it will lock whenever i turn the screen off... this is exactly what i want, but without having to use the passcode. Can anyone help?
