Not to be an ass or anything and I love what fourthgen has done with his locks, but the bottom line is get an alarm and don't leave things of value just sitting out in the open. When they stole my si I got it back with the locks intact and the yes I had locked the car. All of the cars mentioned above I have owned and all have been broken into with minor to no damage done. If we can spend thousands to modify and customize are cars we must be able to shell out some good money to protect it from the petty car thieves. THeres not much to do against the high tech ones but I doubt they want my poor trashed si. When I locked my keys in the car it took me 5 minutes to get them out so a pro would probably do it in less time. Oh and if you don't have the money right away at least get a kill switch it saved my bros old boosted hatch from starting when they tore apart his ignition.
