Understanding Immobilizer Systems and Key Fob Functionality
Modern Mitsubishi vehicles are equipped with immobilizer systems to enhance security. These systems work in conjunction with a transponder chip embedded within your key fob. When you insert your key into the ignition or bring the key fob close to the ignition cylinder (for push-button start vehicles), the immobilizer system communicates with the transponder chip. If the chip’s code matches the car’s system, the engine is allowed to start.
When to Seek Professional Help
While many Mitsubishi key fob issues can be resolved with simple troubleshooting, some situations warrant professional attention:
- You’ve tried troubleshooting steps without success. If you’ve exhausted basic troubleshooting steps and your key fob is still not functioning correctly, it’s best to consult with a professional.
- You suspect a problem with the immobilizer system. Issues with the immobilizer system are complex and require specialized knowledge and equipment to diagnose and repair.
- Your key fob needs replacement. If your key fob is lost, stolen, or damaged beyond repair, you’ll need to obtain a replacement from a Mitsubishi dealership.
