Introduction
In this article, I will share my experience of upgrading my key fob to enable factory remote start. I will walk you through the steps I took, including replacing the radio transceiver module and programming the body control module. If you're looking to add remote start functionality to your vehicle, this article will provide you with valuable insights and guidance.
How I Upgraded My Key Fob for Factory Remote Start
To enable remote start on my vehicle, I needed to upgrade my key fob. The original key fob could only operate at 302 megahertz, while remote start requires a frequency of 902 megahertz. After obtaining the compatible 902 megahertz key fob, I proceeded with the upgrade process.
Replacing the Radio Transceiver Module
To install the new key fob, I had to replace the radio transceiver module located on the headliner of my vehicle. This required removing the B and C pillars, as well as the grab handles. Once I gained access to the module, I swapped the old one with the new 902 megahertz module. It was a tight fit, but I managed to complete the installation successfully.
Programming the Body Control Module
After the physical installation, I had to program the body control module to recognize the new key fob and enable remote start functionality. Following the instructions provided by an email from someone who had done a similar upgrade on their Fusion Hybrid, I attempted to enable remote start directly. Unfortunately, I encountered challenges and had to pursue an alternative method.
Using the New Remote Start Key Fob
Once I resolved the programming issue, I tested the functionality of the new key fob. With the upgraded key fob, I could now lock, unlock, and start my vehicle remotely. The trunk button also worked correctly, although I was still working on achieving automatic trunk closing feature similar to that found in Lincoln vehicles.
Conclusion
Upgrading my key fob for factory remote start was a worthwhile endeavor. By replacing the radio transceiver module and programming the body control module, I was able to enjoy the convenience of remote start functionality in my vehicle. If you're considering a similar upgrade, make sure to follow the recommended steps and acquire the necessary components. With the right tools and information, adding remote start to your car can enhance your driving experience.
Highlights:
- Upgraded key fob enables factory remote start
- Replaced radio transceiver module for compatibility
- Programmed body control module for remote start functionality
- New key fob allows remote locking, unlocking, and starting of the vehicle
FAQ:
Q: Why did I need to upgrade my key fob for remote start?
A: The original key fob operated at a different frequency (302 megahertz) than what is required for remote start (902 megahertz). Upgrading to a new key fob with the correct frequency allowed me to enable remote start functionality.
Q: Was the installation process difficult?
A: The installation process involved removing certain components, such as the B and C pillars, and the grab handles to access the radio transceiver module. It required some precision, but with careful maneuvering, I was able to complete it successfully.
Q: What was the purpose of programming the body control module?
A: Programming the body control module was necessary to ensure that it recognized the new key fob and enabled remote start functionality. It allowed the vehicle's systems to communicate with the upgraded key fob seamlessly.
Q: Can I still use the old key fob for my vehicle?
A: The old key fob, which operated at 302 megahertz, is no longer compatible with the vehicle's upgraded system. However, it can still be used to manually start the vehicle by inserting it into the emergency slot. The new key fob should be used for remote functions.
