Many drivers are curious about whether they can use their existing factory key fob to remote start their vehicles. The good news is, for many vehicles, the answer is yes! Using your OEM (Original Equipment Manufacturer) key fob for remote start is a convenient feature that eliminates the need for an extra remote. However, it’s important to understand both the advantages and limitations of relying on your factory remote for this function. Let’s delve into how factory key fob remote start works, its benefits, and potential drawbacks.
Understanding Factory Key Fob Remote Start Systems
Remote starting your car with your factory key fob typically relies on a system known as “3x Lock Start” or “three times lock start.” This intuitive system is designed to integrate seamlessly with your vehicle’s existing electronics. When a compatible remote car starter is installed, it interfaces with your car’s computer system and security features. The installation process is quite similar to installing a traditional remote starter with aftermarket remotes, often without requiring a separate antenna on the windshield.
The magic happens when you press the “lock” button on your factory key fob three times in quick succession. This action sends a specific signal to the interface module connected to your remote starter. Upon receiving this signal, the module commands the remote starter to ignite your engine. For those with integrated key/remote fobs, this system offers a particularly clean and convenient solution, keeping your keychain clutter-free.
The Convenience Factor: Benefits of Using Your Factory Remote
The primary advantage of using your factory key fob for remote start is simplicity and convenience. You are already accustomed to using your key fob for locking and unlocking your doors, and now you can add remote start to its functions without learning to use a new device. This eliminates the need to carry an additional remote, streamlining your keychain and simplifying your daily routine. For many, the ease of “3x Lock Start” is perfectly adequate for their needs, especially in situations where range isn’t a critical factor.
Range Limitations: Where Factory Key Fobs Fall Short
While the convenience of factory remote start is appealing, the most significant drawback lies in its limited range. Factory key fobs are designed primarily for close-range operation, typically sufficient for locking and unlocking doors as you approach your vehicle in a parking lot. However, when it comes to remote starting from a distance, such as from inside an office building, a shopping mall, or your home, the factory remote’s range can be insufficient.
Imagine the frustration of thinking you’ve started your car from indoors on a cold morning, only to find it still unheated when you reach it. This range limitation is the main reason why some users find factory key fob remote start systems inadequate for their needs.
Exploring Aftermarket Remote Options for Extended Range
For those requiring greater range and reliability, aftermarket remote starters offer superior performance. Even basic aftermarket remotes typically provide a range of at least 800 feet, with high-end options extending to a mile or more. Furthermore, many aftermarket remotes offer two-way communication, providing visual or audible feedback to confirm that your vehicle has successfully started. This eliminates the guesswork and uncertainty associated with factory key fob systems when starting from a distance.
If you desire the ultimate control and convenience, consider advanced telematics systems like Viper SmartStart. These systems allow you to control your remote start, door locks, and even trunk release from your smartphone via an app. Premium services can also include GPS vehicle tracking and customizable alerts. Combining a SmartStart system with factory key fob compatibility offers a versatile solution, providing both short-range and long-range control options.
Choosing the Right Remote Start Solution for Your Needs
Deciding whether to rely solely on your factory key fob for remote start or to explore aftermarket options depends on your individual needs and preferences. If short-range starting is sufficient for your lifestyle, and you value simplicity above all else, a factory key fob compatible system might be a good fit. However, if you require reliable remote start from a greater distance, or desire advanced features and confirmation feedback, an aftermarket remote system is highly recommended.
For expert guidance and professional installation, it’s best to consult with remote start specialists. Professionals can assess your specific needs, demonstrate the capabilities of different systems, and recommend the ideal solution for your vehicle and lifestyle. Whether you opt for the convenience of your factory key fob or the extended range of an aftermarket remote, the goal is to enjoy the comfort and convenience of a remote started vehicle.
