  1. Sue, as much as we would like to help you, not all car alarms are installed the same way. Different brands and different setups will call for different wiring. Our advice is to take your car to a qualified alarm installer and ask them to remove the alarm because it does take some wiring knowledge and experience to know what to remove. Hope this helps. Good luck on your alarm removal.

  2. my 98 toyota tacoma got the battery jumped for the first time since i bought it (used 5 years ago). Afterwards, the alarm system was activated and i can’t disable it. i had no idea there was an alarm system even in the car. it goes off when the door opens or when i hit a bump, and every few minutes. what a pain! any idea how to disable the alarm?!
