I am looking at the Powerlock system. I don't know if it is a good system or not If anyone knows more about it let me know. I guess I can get it installed with my factory alarm system. I kills the starter and from what they say you can't hotwire the car. I know that if they want your car they will take it but I want to make it as hard a possible so they want to go for a different car. The link to the Powerlock web site is http://www.powerlock.com/consumerfront.asp . Please let me know if I should go with this system. Thanks all.
