The way the club works is by telling the potential thief "The owner is determined enough to make his own life a little bit more difficult. You don't know what else might be there, just go along and find an easier target." The best way to secure your car is to think like a thief. Look at it and ask yourself, "Is this a good target?" Thieves evaluate the car through risk / reward but mostly risk. The cost of being caught is very high and opportunity cost is very low -- there is a lot of other cars available so there is almost never a reason to steal this particular one. So naturally if they see any warning signs that this might be risky (even something like an out of place pulsing light) they might want to skip it for something else. Thus, the best way to not have your car stolen is: 1) Do not drive expensive car (low reward) 2) Display something in your car that tells the thief you are determined owner and you will make the thief's life difficult (high risk) 3) Remove absolutely everything from your car that can be stolen. When I go on vacation (ie. car with foreign license plates more likely to have valuables in the trunk) I even removed the shelf above the trunk so that a thief can look and see the trunk is empty. (no easy, risk-free, alternative payoff) 4) Have an actual safety like a concealed switch that prevents the car from being started. Do not ever use anything that has visible elements -- the thief must try to start the car, see that it does not start and see that it is not easily possible to identify the mechanism that prevents starting. This should deter potential thief to try any further.
