1.replace your drivers side outer handle with a regular passenger side handle (no key hole). Even with a alarm as soon as the lock rod reads unlock signal by a falling key tumbler it's deactivates the alarm.
2.fabricate a backing plate on the ECU under the hood on the drivers side near second battery tray. Thief's(really good ones) reprogram ECU's to your vehicle ahead of time, so they have no trouble starting your car. Jump in, pop the hood, swap out ECU, starts right up.
3.second battery option(especially if you are using the #1 option) prevents power cable on the right hand side fender well to be tampered with.
4.a really good alarm with a pager to notify you that someone is messin with your ride. Shatter sensors are good too being they sense certain frequencys that broken or breaking glass produce.
