This means you need to be relatively close to your vehicle for the system to work. Obstructions like buildings can further reduce the range.
Another limitation involves safety features. Most remote start systems have built-in safeguards to prevent accidental starting or theft. For example, the engine will typically shut off after a set period (e.g., 10-15 minutes) if the vehicle is not entered and driven. Also, some systems will not allow remote start if a door is ajar or the hood is open.
Does remote start drain the car battery?
Using remote start does consume battery power, but the impact is generally minimal under normal usage. The amount of battery drain depends on factors such as the duration of remote start operation, the vehicle’s charging system, and the overall health of the battery. If the car is driven regularly and the charging system is functioning correctly, the battery should be sufficiently recharged during normal driving.
However, frequent and prolonged use of remote start, especially in conjunction with short driving distances, can potentially lead to battery drain over time. In such cases, it might be beneficial to occasionally drive the car for longer periods to allow the battery to fully recharge or to use a battery maintainer when the car is not in use for extended durations.
What should I do if my key fob remote start suddenly stops working?
First, check the key fob’s battery. A weak or dead battery is a common cause of remote start failure. Replace the battery with a fresh one of the correct type as specified in your owner’s manual. If replacing the battery doesn’t resolve the issue, check the vehicle’s hood and door sensors to ensure they are functioning properly. A faulty sensor might prevent remote start from engaging as a safety measure.
If the problem persists after checking the battery and sensors, there could be a more complex issue with the remote start system itself. This could involve a problem with the vehicle’s computer, the wiring, or the remote start module. In such cases, it’s best to consult with a qualified mechanic or your dealership to diagnose and repair the issue. They can use diagnostic tools to identify the root cause and perform the necessary repairs or reprogramming.
