Try the door. I’ve gone to houses and found it open. (I’m still going to charge you for the service call.)
If your key won’t turn, try WD-40 or silicone spray. Sometimes the pins get jammed up, and 25 to 40 percent of the time that solves the problem.
Don’t call multiple locksmiths
If you’re locked out, please call just one of us. More than once, I arrived at a lock-out to find two competitors’ trucks already there. At that point, we all agreed to leave and abandon the inconsiderate victim.
