I have a 99 Chevy Suburban K-1500 w/barn doors. How do I take off the outer door handle to remove tge lock cylinder? The power lock won't work so I was using the key for awhile to lock and unlock the door. Now the key goes in but won't turn. I've taken off the inside panle but I do not see any bolts holding it on like the front doors. Any help would be greatly appreciated.

Thanks,
Mike
