The Empty Or Dead Battery In The Key Fob

A battery with an electric connection is the main power source for running any electric device. So when you fail to provide that power to the electric device, you will definitely find some issues.

Wrong Key Fob Programming

Key fobs are small, portable, and fantastic devices that allow owners to control a vehicle remotely. A fob has two main functions: it must be able to store a security code that provides access to the jeep, and it must transmit that code to the vehicle to unlock the doors.

So, the key fob is all about programming. If something is wrong with the security code of the vehicle, the whole key fob system is abortive.

Is there any key broken or miss-aligned in your key fob? it can happen anytime when the key fob falls from your hand. If you find a tiny crack or a minor scratch on the fob, then that may be the reason why it is not working.

The Problem With The Door Lock System

when we say only the faulty key fob is responsible for each problem, that would be one-sided. Sometimes, you can find key fob issues if the door lock system or panoramic sunroof is faulty.

When every feature in the key fob is working pretty well without the lock system, maybe the key fob is okay, and the problem is arising from the door.

Using Multiple Wireless Devices

The jeep is the place where we tend to keep our electronics, but having multiple wireless devices in the vehicle can ensure quality riding, commuting, and jeep anti-theft system.

When you’re driving, especially on the highway in Sport mode, distractions are everywhere by text messages, social media alerts, and news updates. All wireless devices like wifi, radio, and Bluetooth use different frequencies to keep the system alive.

Sometimes, the key fob faces problems in ensuring its services among all the frequencies. So, it could be one of the causes of key fob problems in jeep Cherokee, Grand Cherokee, Rubicon, or Willys.

Weak Or Dead Jeep Battery

Without a working battery, you can not drive to a nearby dealer to purchase new batteries; that’s why a Jeep battery is a critical part of the vehicle.

When your vehicle battery is weak or dead, all the electronics systems fail to run until you fix it. Sometimes, a weak battery will not allow you to run a key fob system in your jeep.

What is the range of key fob in Jeep Grand Cherokee?

In an era where convenience is king, automotive manufacturers are constantly pushing the boundaries to enhance the driving experience. One such innovation is the key fob, a device that has revolutionized the way we interact with our vehicles. Among the many vehicles offering advanced key fob functionality, the Jeep Grand Cherokee stands out with its impressive range.

The key fob of the Jeep Grand Cherokee is not just a simple device for locking and unlocking doors; it offers a range of features that make accessing and operating your vehicle a breeze. Whether you’re approaching your SUV from a distance or looking to start the engine remotely, the key fob brings convenience to the forefront of your driving experience.

The Jeep Grand Cherokee, renowned for its impressive features, takes this experience to new heights with its advanced key fob functionality. Offering a range of capabilities such as Passive Entry, Remote Keyless Entry (RKE), Keyless Enter ‘n Go™, Remote Start, and remote power liftgate operation, the key fob of the Jeep Grand Cherokee brings an unparalleled level of convenience to your driving experience.

Range without remote start feature

The key fob of the Jeep Grand Cherokee allows you to effortlessly lock or unlock all doors and the liftgate, and even activate the Panic Alarm from a considerable distance of approximately 66 feet (20 meters). Notably, the key fob does not require direct alignment with the vehicle to initiate these actions, providing ease and flexibility in its operation.

Range with remote start feature

Vehicles equipped with remote start feature, the key fob can operate from distances of up to 328 feet (100 meters), granting you the freedom to start your Jeep Grand Cherokee remotely.

With the remarkable range and comprehensive features of the key fob in the Jeep Grand Cherokee, drivers are empowered with a heightened level of control, accessibility, and security for their vehicle.

Signal interference can reduce range

The key fob of the Jeep Grand Cherokee, while offering a range of impressive features, can be susceptible to interference when placed near certain electronic devices such as mobile phones and laptops. This interference can impact the key fob’s wireless signal, resulting in reduced range.

To ensure optimal functionality and performance of your key fob, it is crucial to be aware of potential interference from nearby electronic devices. When the key fob is in close proximity to mobile phones, laptops, or other electronic devices, the wireless signal may become blocked or disrupted. This can manifest as poor responsiveness or even a complete loss of communication between the key fob and the vehicle.

To mitigate any potential issues, it is advisable to keep electronic devices at a reasonable distance from the key fob. Avoid storing them in the same pocket or compartment to minimize the chances of interference. By maintaining this separation, you can ensure that the key fob operates reliably, allowing you to unlock or lock your Jeep Grand Cherokee, activate the panic alarm, or utilize other features without any hindrances.

Weak key fob battery can reduce range

A deteriorating key fob battery can have a direct impact on the range and performance of this essential device, potentially causing inconvenience and frustration for Grand Cherokee drivers.

A key fob relies on a small battery to transmit wireless signals to the vehicle, enabling functions such as locking or unlocking doors, activating alarms, and even remotely starting the engine. When the battery inside the key fob weakens over time, its ability to generate and transmit a strong signal diminishes, resulting in a reduction in range performance.

As the key fob battery weakens, the effective range at which it can communicate with the vehicle becomes compromised. Actions such as locking or unlocking doors may require closer proximity between the key fob and the vehicle. In some cases, drivers may even need to place the key fob directly against the car’s body for the signal to be received, significantly limiting the convenience and ease of use that the key fob provides.

To avoid such issues, it is essential to regularly check and replace the key fob battery as needed. Most key fobs utilize readily available and easily replaceable coin or button batteries. By replacing the battery in a timely manner, vehicle owners can ensure that their key fob maintains optimal range performance, allowing them to interact with their Jeep Grand Cherokee from a comfortable distance without any signal degradation.
