If your car alarm goes off when you sit in the car, it could be due to a sensitive shock sensor, a faulty door latch, or a malfunctioning key fob. To address this, start by checking the sensitivity of your car’s shock sensor and adjust it if necessary. If the issue persists, inspect the door latches for damage or wear and repair or replace them as needed. Lastly, examine your key fob; if it's damaged or the battery is weak, consider replacing the battery or the fob itself. Consult your vehicle’s manual or a professional if needed.
