Keyless entry cars can be easily unlocked and stolen with a relay (basically any key where you don't have to press a button to unlock/start. If you keep your keys by your door, they can just step up to your door, hop in your unlocked car, start it and drive away
I had some left over lead and lined my keybox, took about 1/2 hour, the side cuts were the only skilled part, the rest just unfolds. And then screwed 2 pieces on the top
I highly recommend
