The Complete Overview of How to Remote Start a 2020 Jeep Grand Cherokee
The 2020 Jeep Grand Cherokee’s remote start system is a study in seamless integration, combining physical key fob commands with digital vehicle diagnostics. Unlike earlier models that relied on standalone remote start modules, Jeep’s approach in 2020 weaves this functionality directly into the Uconnect® 4C interface, which also manages navigation, connectivity, and driver-assist features. This unified system ensures that remote start commands are processed in real-time, with feedback delivered via the infotainment display or even through voice prompts. The process begins with the key fob, which communicates via a 315 MHz radio frequency signal—a standard in modern keyless entry systems—but the actual engine start sequence is governed by the vehicle’s body control module (BCM) and powertrain control module (PCM). These modules interpret the signal, verify security protocols (including immobilizer checks), and only then authorize the starter motor to engage.
What sets the 2020 Grand Cherokee apart is its adaptive learning capabilities. The system remembers your preferred remote start settings, such as climate control preferences and seat positions, and can even sync with third-party apps like Jeep’s MyJeep® for remote monitoring. However, this sophistication comes with complexity. For example, the vehicle must be within a 30-foot (9-meter) range of the key fob for the remote start command to register, and the battery must have sufficient charge—not just to power the starter but also to support the Uconnect® system’s wake-up sequence. Neglecting these details can lead to false starts or complete system failures. The key to success lies in understanding the interplay between hardware (the key fob, BCM, and PCM) and software (Uconnect® firmware), ensuring every component is in harmony before attempting to start the vehicle remotely.
Historical Background and Evolution
The concept of remote starting vehicles dates back to the 1980s, when aftermarket solutions emerged as luxury add-ons for high-end cars. By the 2000s, automakers began integrating these systems into production models, with Jeep leading the charge in the SUV segment. The 2011 Grand Cherokee introduced Jeep’s first factory-installed remote start system, a feature that quickly became a standard in higher trims. However, these early implementations were often clunky, requiring separate buttons on the key fob and lacking the intuitive feedback of modern systems. The 2020 model marked a significant evolution, as Jeep consolidated remote start functionality into the Uconnect® 4C platform, eliminating the need for auxiliary hardware and streamlining the user experience. This shift mirrored broader industry trends toward centralized vehicle control modules, where features like remote start, keyless entry, and even vehicle diagnostics converge under a single digital interface.
Jeep’s decision to embed remote start within Uconnect® wasn’t just about convenience—it was a strategic move to enhance security and diagnostics. The system now includes encrypted communication between the key fob and the vehicle, reducing the risk of signal hijacking or unauthorized access. Additionally, the integration allows for over-the-air (OTA) updates, meaning Jeep can refine the remote start algorithm without requiring physical dealer visits. This level of adaptability is rare in automotive systems, where hardware upgrades often necessitate costly recalls. For owners of the 2020 Grand Cherokee, this means their remote start capability can improve over time, provided they keep their Uconnect® system updated. The historical progression of remote start technology in Jeep vehicles underscores a broader automotive industry shift: from standalone features to integrated, intelligent systems that learn and adapt alongside the driver.
Core Mechanisms: How It Works
Under the hood, the 2020 Jeep Grand Cherokee’s remote start system operates through a multi-step sequence that begins with the key fob and culminates in the engine’s ignition. When you press the remote start button on your key fob, a 315 MHz radio signal is transmitted to the vehicle’s body control module (BCM). The BCM then verifies the signal’s authenticity using a challenge-response protocol, ensuring it’s not a spoofed or intercepted command. Once authenticated, the BCM sends a wake-up signal to the Uconnect® system, which powers up the infotainment display and activates the vehicle’s climate control settings (if pre-programmed). Simultaneously, the BCM communicates with the powertrain control module (PCM), which checks for additional security clearances, such as the immobilizer status and battery voltage levels. Only after all these checks pass does the PCM authorize the starter motor to engage, turning the engine over.
The entire process is designed to minimize wear on the starter and alternator, which is why the system includes a "pre-conditioning" phase. During this phase, the Uconnect® system activates the climate control before the engine starts, ensuring the cabin reaches the desired temperature without unnecessary strain on the battery. This is particularly useful in extreme climates, where remote starting can help preserve battery life while still providing comfort. However, this mechanism also introduces a potential point of failure: if the battery voltage drops below a critical threshold (typically around 11.5V), the system may refuse to start the engine remotely to prevent damage. Understanding this interplay between electrical components and software logic is crucial for troubleshooting, as issues often stem from either a weak battery or a misconfigured Uconnect® setting.
