I have to agree with Impressive here. I attended plenty of home invasions where the occupants were woken up/beaten because the offender/a couldn't find the keys to their high powered cars. Also attended plenty where the offender/s have broken in through a rear door, grabbed the keys from the kitchen bench and left without making a noise.... Let them take the car, the less time they spend in your house the better.
Even consider carrying out anti surveillance runs when you're close to home, do a few laps, go down a dead end street and take note of any vehicles that follow you.... All basic stuff that will take an extra 5 mins of your day. I'll be at the cruise on the 4th so happy to offer any info.
