i went down a high kerb and it landed on the front sills . no damage but next day the car wouldn't open with the zappers. opened the car with the metal key, the alarm went off and non start. called the rac who checked it over , but no luck . they recovered it to a local garage, but after 3 weeks still unable to find the fault. i believe there's a roll over switch but cant find it. any help or suggestions as to why zappers not working? (new battery's fitted)
