I know how annoying blackjax can be but at the end of the day, it can save your car getting stolen via thieves burgling your house and taking your keys. If they want to tow it away, they will tow it. So best thing to do is park off the road where they can't get a tow truck in to tow it away and get the blackjax on. You don't even have to have an amazingly fantastically complex code, just something that will prevent a thief being able to drive your car away with your keys.
