I am a dedicated worker that will show up when I say I will. I will work on any project as if it were my own home. If it is an install, it will be done correctly the first time. If it is a repair, it will be repaired correctly. I do not believe in taking shortcuts on my personal projects, and I will not take shortcuts on any project. I will handle the task quickly, correctly and efficiently every time.

Lock bumping is a technique locksmiths use to quickly and quietly open a pin tumbler lock, typically found in most types of deadbolts.
