The ProStar 2-way OLED Car Alarm Remote does more than lock and unlock your car, it is capable of checking the current temperature within the cabin, alerts you if the door, trunk, or hood is open, pages the driver whenever somebody tries to get away with your car and features a timed engine start, a remote engine start/starter kill, and even a window tap PIN that locks and unlocks your car. The entire kit costs $285, while dropping another $50 will snag you the Watchcon wristwatch remote unit for those who don’t want to be seen carrying the main system around.
