Automatic start or push-button ignition has become a popular feature in modern cars. It provides convenience and ease of use for drivers. However, if your car's automatic start is not working, it can be frustrating and inconvenient. In this article, we will discuss the common causes of automatic start failure and what you can do to fix it.
Causes of Automatic Start Failure
Dead Key Fob Battery
One of the most common causes of automatic start failure is a dead key fob battery. The key fob transmits a signal to the car's computer to start the engine. If the battery is dead or low, the signal may not be strong enough to start the engine. Replace the key fob battery and try again.
Ignition System Issues
If the battery is not the problem, then there may be an issue with the ignition system. The ignition switch, starter motor, or battery may be malfunctioning. A faulty ignition system can prevent the engine from starting, even if the key fob is transmitting the signal correctly. Have your car checked by a professional mechanic to diagnose the problem.
How to Fix Automatic Start Failure
Replace Key Fob Battery
If the issue is a dead key fob battery, replace it with a new one. Most key fobs have a small screw or latch that allows you to open the casing and replace the battery. Consult your car's owner's manual or a professional mechanic if you are unsure how to replace the battery.
Check Ignition System
If the key fob battery is not the issue, then have your car's ignition system checked by a professional mechanic. They can diagnose and repair any issues with the ignition system, such as a faulty ignition switch, starter motor, or battery.
Reset Car's Computer
Occasionally, the car's computer may need to be reset to fix issues with the automatic start system. This can be done by disconnecting the car's battery for a few minutes and then reconnecting it. However, be aware that resetting the computer may also reset any custom settings and erase radio presets.
Preventing Automatic Start Failure
Maintain Key Fob Battery
To prevent automatic start failure due to a dead key fob battery, maintain the battery by replacing it before it dies completely. Keep an extra battery on hand in case of an emergency. Also, avoid exposing the key fob to extreme temperatures or water, as this can damage the battery.
Maintain Ignition System
To prevent automatic start failure due to ignition system issues, maintain the ignition system by having it checked regularly by a professional mechanic. Replace any faulty parts as soon as possible to prevent further damage and breakdowns.
Use OEM Parts
When repairing or replacing parts in your car's automatic start system, use OEM (original equipment manufacturer) parts. These parts are designed specifically for your car and are guaranteed to work correctly. Using aftermarket parts may cause compatibility issues and may not work as intended.
In conclusion, automatic start failure can be frustrating and inconvenient. However, by understanding the common causes and how to fix and prevent them, you can ensure that your automatic start system works correctly and provides the convenience and ease of use it was designed for.
