A remote start fires the engine from a fob or your phone, so the car is warm and the glass is clear by the time you walk out. On a North Jersey January morning that is worth a lot on the first turn of the day.
A remote start ties into the ignition and the security system. Done wrong it drains a battery or throws a fault. We wire it into the car clean so it starts every time and does not fight the alarm.
Most people add a car alarm and hands-free Bluetooth at the same time, since the dash is already apart. One visit, one clean harness.
