1 or 2 clamp lock pliers on each garage door track is a great addition to electronic security. I never leave a firearm in an unattended vehicle. If I'm going somewhere (post office, school, govt. facility, etc.) where carry is prohibited, the firearm stays home in the safe even though my car alarm sends an immediate alert to my phone when activated. Usually, I'll visit the prohibited facility first, then return home to strap up. For jury duty or renewal of my carry permit, I was pleased to learn that our county courthouse has an attended firearm checking vault with a 2 key lock system like a bank safety deposit box, one for me and another for the attending officer.
