Electrical – Potential danger installing longer strike plate screws

doorsdrillelectricalscrews

Just changed the locks on my house today, and I noticed that the strike plate screws that came with my new deadbolts are much longer than the existing strike plate screws.

I'm using the old screws for now, but I assume the longer screws are more secure (and the color matches), so I'd like to use the new ones if possible.
I'm worried about drilling horizontally into something near the doors, so I was wondering if the area around a door is typically safe, or if I could use some tool to confirm before drilling anything.

Thanks!

Most wood frame houses use at least two 2x4s or 2x6s(stud plus a jack post) plus the door frame at doors/windows. That gives minimum of a bit more than three to 3½" inches before hitting something.
