Android Button Re-map

[YnYng]

Basically what the title says. Is it possible to remap the keys? My "end" key is starting to get depressed and its gettin harder to push it so i dont want to push too much and have it break, but i need the phone to lock when im done using it, so would it be possible to change the "end" key function which is lock to the "power" button, b/c as of now, tht doesnt seem to do much except wake the screen while in lock.

thanks for any help guys, im runnin ASOP jun 16th, as an FYI
