Watch Out: What Fiat 500 Keys Is Taking Over And How To Stop It
Fiat Panda Key Fob Replacement
Fiat Panda key fobs contain a transponder chip which sends signals to your car to open the doors or start the engine. The fob can stop functioning for a variety of reasons.
The most commonly cited reason for key fob failure is an inoperable coin battery. Other causes include water damages, a faulty module, and interference signals.
Dead Coin Battery
Replace the battery in case your key fob has died. Choose a new button battery with the same voltage, size and specifications as the original.
If the key fob was exposed to water (such as saltwater or rain at the beach) It must be cleaned prior to using it again. The best method is to use a paper towel that has been soaked in isopropyl, or electronic cleaner.
If the key fob has not been exposed to water, but isn't working it could be an issue with the receiver module or an internal electronic chip. Reprogramming the keyfob using an OBDII scan may aid in these situations.
Water Damage
If your key fob has gotten an immersion in the puddle or pool, or taken a trip through the washing machine, you might have some water damage. It is usually possible to get it back to working by removing the battery and scrubbing the circuit board with isopropyl alcohol. It is a good idea to allow the fob to dry completely before putting in a new battery.
If your key fob stopped working, even after replacing the battery and changing the program, you could have a problem with the receiver module. You can find instructions for reprograming the majority of remote keys on YouTube or consult the owner's manual. You could also try resetting the car's onboard computer with the OBDII scan tool.
Faulty Receiver Module
The key fob contains a chip that communicates with the vehicle's system. If this chip becomes damaged, it cannot longer transmit and receive signals to the vehicle. A key fob falling off can cause this, as can exposure to water. If your key fob stopped working due to exposure to water and you are unable to fix it by attempting to clean the chip using electronic cleaner or isopropyl alcohol.
If the key fob continues to not respond after cleaning it, it is likely that the module is defective and must be replaced. A faulty receiver can also cause the key to stop working. This is usually caused by electromagnetic interference.
A defective electronic chip
The electronic chip in your key fob is a vital part of the anti-theft system in your car. It sends a signal the immobiliser unit inside your car to inform it whether the key is valid. Your car won't start in the event that the chip has been damaged.
A damaged chip could be caused by interference signals from other objects, bad weather conditions or transmitters on the same frequency in close proximity to your vehicle. In this instance, you will need a new key fob.
Contacts to the battery are not working properly.
The battery contacts in the key fob are delicate and can get damaged when used for long periods of time. If they're bent, or broken, the fob won't send any signals to the receiver modules inside the vehicle.
Modern fobs come with rubber seals that keep out water. In the event of submerging them in water, even if it's just a light drizzle or splash could harm the chip's electronic components.
The key fob is equipped with the chip that connects to the vehicle's immobilizer in order to activate it. This system makes use of cryptocoding systems in the latest vehicles or the red key system for older ones. This chip needs to be replaced if it's defective.
A faulty 12 Volt battery
A defective battery can cause the key fob to work. The car's computer won't recognize the remote if this happens.
Before you replace the battery, test it using a an voltmeter for determining its capacity. A fully charged battery should read 12.6 volts. If the reading drops significantly, it's time to replace it.
To test the battery's power to determine its capacity, put an electric load on it for a few minutes. This will eliminate 1% of the surface charges. After fiat 500 key fob replacement , take the voltage once more. The longer a battery is able to hold its voltage and the higher its capacity. The ideal scenario is to keep it close to 12 volts for several minutes.
The radio signal is not working properly. Radio Signal
This is the most common reason for a key fob that ceases to send signals to the car. The issue can be fixed by replacing the battery. However, it is important to buy a new battery with the same size and voltage as the original.
Fobs are subject to a lot of abuse, but they're also not impervious to destruction. Battery contacts and buttons can be damaged by rough handling.
A signal can also be interrupted by other transmitters or objects which use the same frequency. For instance, a lighting control panel near your home may transmit interference on the same frequency that key fobs utilize. This could interfere with the remote control of your car.
The tool is not working properly. OBDII scan tool
There are many reasons why a scanner could not work. Some are more complicated than others.
Professional scan tools enable mechanics to observe the car's networks and run a range of self-tests. These tools can save a lot of time, but they are costly and out of reach for most DIYers.
If your OBD2 scanner won't turn on, check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If both are in good condition the fuse could have blown. This is the most typical reason for a scan tool to fail. It is generally simple to fix the issue by replacing the blown fuse.
