Handcuffs are not a very good way to secure something from theft. There are plenty of handcuff keys out there. They're available on Amazon.
Being a creature of habit works against you. Can't carry at work so everyday you get to the parking lot and fiddle with "something" there daily? This was not a crime of opportunity I think. The thief must have seen you do this before and came prepared to deal with it.
I grew up a city boy and avoid leaving anything of value in my car. If I have to I'm as discreet as possible hiding or securing it. For example I use a soft cooler as a camera bag. If someone sees me put it in the trunk when I leave the car they think it's a cooler not a few thousand dollars of camera equipment.
