What Does It Mean That Chrysler 200 Key Fob Not Detected?
When a Chrysler car saying key not detected, the vehicle’s receiver system cannot recognize or communicate with the key fob.
It contains a transmitter that sends a unique signal to the receiver, allowing the car to identify and verify the presence of the key fob.
Suppose the car displays a “Key Fob Not Detected” message or fails to respond to the key fob’s commands.
It suggests that there is an issue with the signal transmission or reception between the key fob and the car’s receiver. You can check this guide if your key fob can’t unlock the automobile.
Reasons Why A Chrysler Key Fob Not Detected
Let’s explore the possible causes behind this relatively common issue!
Dead Battery In The Key Fob
Over time, the battery in your key fob may lose its charge, resulting in a weakened or low signal to communicate with your vehicle’s immobilizer system.
This can prevent the key fob from successfully unlocking or starting the car, triggering the error message.
To determine whether a bad battery is the cause, use the physical key to unlock the vehicle or access the emergency key slot manually.
Suppose the manual key works; it indicates that the key battery needs replacing.
Damaged Key Fob
A damaged key fob can disrupt the communication between the fob and the vehicle’s immobilizer system, whether it’s due to accidental drops, rough handling, or wear and tear over time.
Signs of key fob damage may include visible cracks on the casing, broken or unresponsive buttons, or a loose battery compartment.
These issues can prevent the key fob from sending the necessary signals to unlock or start the vehicle.
Internal components of the key fob, such as the circuit board or antenna, can also become damaged, further hindering its functionality.
Interference From Other Electronic Devices Like Radio
Strong radio signals in the vicinity can interfere with the communication between the key fob and the vehicle’s receiver, resulting in this common warning message.
This electrical interference can disrupt the key fob’s transmission and prevent it from successfully sending signals to unlock or start the car.
To troubleshoot this issue, move away from potential sources of radio interference, such as radio towers, power lines, or other electronic devices.
Try using the key fob in different locations to see if the error persists. Additionally, ensure no obstructions or interference-blocking materials around the key fob or the vehicle’s receiver.
Malfunction In The Car’s Keyless Entry System
The remote keyless entry system, which allows you to effortlessly lock, unlock, and start your vehicle with just the push of a button, relies on a complex network of sensors, antennas, and modules to communicate with your key fob.
However, if any of these components encounter a glitch or fail to function properly, it can lead to the key fob not being detected.
This issue can leave you stranded, unable to access your car, or start the engine.
Use The Wrong Key
Did you know that using the wrong key can be one of the causes behind your 2015 Chrysler 200 key fob not detected?
It may sound simple, but it’s a mistake that can easily happen, especially if you have multiple keys for different vehicles.
The key fob is specifically programmed to communicate with your car’s keyless entry system, and using an incorrect key that doesn’t have the necessary programming will prevent the system from recognizing it.
This can result in frustration and confusion as you try to figure out why your key fob isn’t working.
Bad Car Battery
The key fob relies on a steady and reliable power source to communicate with the vehicle’s keyless entry system.
Still, suppose your vehicle battery is weak or nearing the end of its lifespan.
In this case, it may not provide enough power to properly operate the keyless entry system, resulting in the key fob not being detected.
Let’s say you find your car battery won’t hold a charge. This guide will help you out!
Loose/Broken Button
Over time, the buttons on the key fob can become worn out or damaged, resulting in a poor connection with the keyless entry system.
When the button is pressed, it may not register the signal properly, leading to the key fob not being detected by the car.
To troubleshoot this issue, carefully inspect the buttons on your key fob for any signs of damage or looseness.
Poor Battery Connector Terminals
The battery terminals interface the car battery and the key fob, allowing the power to flow smoothly.
Over time, these parts can become dirty or corroded, hindering the electrical connection.
When the connection is compromised, it can prevent the key fob from being detected by the vehicle’s keyless entry system.
Bad Car Lock
The car lock mechanism is crucial in facilitating communication between the key fob and the auto’s keyless entry system.
If the car lock button is faulty or experiencing issues, it can interfere with the reception and transmission of signals, resulting in the key fob not being detected.
One common indicator of this problem is difficulty or inconsistency in manually locking or unlocking the vehicle using the physical key.
It’s worth noting that a bad lock can be caused by various factors, such as worn-out tumblers, damaged internal components, or electrical malfunctions.
Deprogramming
Deprogramming is when the key fob loses its programming or becomes unpaired from the vehicle’s keyless entry system.
This can happen for various reasons, such as a weak battery in the key fob, a glitch, or accidental button presses that trigger the deprogramming process.
When the key fob is no longer programmed correctly, the car’s keyless entry system won’t recognize it, resulting in the key fob not being detected.
How To Solve The Chrysler Key Fob Not Working Problem
There are several simple troubleshooting steps you can take to resolve this problem.
Replace The Key Fob Battery
Changing the key fob battery is a simple, cost-effective solution that often solves the problem. It also restores proper communication between the key fob and the vehicle’s immobilizer system.
Step 1: Locate the battery compartment on your key fob.
Step 2: Open the compartment with a small screwdriver or a coin.
Step 3: Replace the old battery with a new one of the same type and ensure it is inserted correctly.
Step 4: Close the battery compartment and test the key fob to see if the issue is resolved.
Check The Key Fob For Physical Damage
Examine the key fob carefully for any signs of physical damage, such as dents, cracks, or loose components.
Physical damage can affect its ability to transmit the signal properly, leading to detection issues.
When you find any visible damage, it may be necessary to repair or replace the key fob. Contact a professional locksmith or dealership to assess the damage and provide the appropriate solution.
Move Away From Sources Of Interference
As mentioned before, various factors can disrupt the key fob’s signal, making it difficult for the vehicle’s receiver to recognize it.
Interference can come from nearby electronic devices, such as mobile phones, Wi-Fi routers, or other key fobs in close proximity.
To rectify this issue, try stepping away from potential sources of interference and creating some distance between them and the key fob.
