Why Nobody Cares About Fiat 500 Keys
Fiat Panda Key Fob Replacement
Fiat Panda key fobs contain transponder chips that send the signal to your vehicle to open the doors and start the engine. The fob could stop working due to a variety reasons.
A dead coin battery is the most frequent reason for the malfunction of a key fob. Other reasons include water damage, malfunctioning receiver modules, and signal interference.
Dead Coin Battery
Replace the battery if your key fob has failed. Choose a new button battery with identical in size, voltage and specifications like the previous one.
If the key fob has been exposed to water, for example a splash of rain or salt water on the beach, it's going to need to be cleaned before it is able to be used again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner will be the solution.
If the key fob isn't working despite being not exposed to water, it could be due to a malfunction in the receiver module or an internal electronic chip. In these situations you can reprogramme the key fob using an OBDII scanner might help.
Water Damage

If your key fob has gotten a bath in the puddle or pool or walked down the washing machine, you might have some water damage. You can usually get it back to working by taking the battery off and cleaning the circuit board with isopropyl alcohol. It's best to let the board completely dry before putting in batteries.
You may have a faulty module in the event that your key fob stops working after replacing the battery or changing the programming. You can find reprogramming procedures for the majority of vehicles' remote key fobs on YouTube or in the owner's manual. You can also reset your computer of your vehicle using the OBDII scanner tool.
Faulty Receiver Module
The key fob's chip is an electronic chip that communicates with the car's system. If this chip becomes damaged, it cannot longer send and receive signals to the vehicle. The key fob being dropped can cause this, as can exposure to water. If the key fob stopped working after exposure to water it may be possible to fix the issue by cleaning the chip with isopropyl alcohol or an electronic cleaner.
If the key fob does not respond after cleaning it, then it is likely that the component is damaged and needs to be replaced. g28carkeys.co.uk damaged receiver module may also cause the remote control key to stop functioning. This is often caused by electromagnetic interference.
Faulty Electronic Chip
The chip that is embedded in the key fob is an important part of the anti-theft system in your car. It sends out a signal the immobiliser unit of your car to determine whether the key is genuine. Your car won't start when the chip is damaged.
A faulty chip can also be caused by interference signals from other objects like bad weather conditions or transmitters on the same frequency close to your vehicle. In this case the replacement fob will be needed.
Faulty battery contacts
The battery contacts of the key fob could be damaged by excessive usage. If they're broken or bent, the fob won't send any signals to the receiver modules in the car.
Modern fobs are made with rubber seals that keep out water. A splash of water or light rain is acceptable however, submerging them in salt water could cause damage to the chip's electronic components.
The key fob has the chip that connects to the vehicle's immobilizer system in order to allow it to start. This system uses crypto coding systems in the latest vehicles or the red key system in older ones. If the chip is not working properly it must be replaced.
Problematic 12 Volt Battery
A damaged battery can cause the key fob to cease working. If this happens the car's computer won't recognize that the remote is inside the vehicle.
Before replacing the battery, test it by using a a voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading drops significantly then it's time to replace the battery.
Set an electrical load for a short period of time on the battery to determine its capacity. This will remove 1percent of the charges. After that, take the voltage once more. The longer a battery is able to hold its voltage, the better its capacity. It should be close to 12 volts several minutes.
Radio Signal Faulty Radio Signal
This is the most typical reason for a key fob that stops sending signals to the car. The battery can be replaced to solve this issue. It is important to buy a battery with the same dimensions and voltage as the original.
The buttons are not impervious to destruction and can be damaged by a lot. Battery contacts and buttons can be damaged by rough handling.
The signal could also be impacted by other objects or transmitters which use the same frequency. A light-control panel at your home, for example could interfere with key fobs using the same frequency. This can interfere with the remote control of your car.
Problems with OBDII Scan Tool
There are many reasons why a scanner might not work. Some are more complicated than others.
Professional scan tools enable mechanics to examine the car's systems and perform a variety of self-tests. These tools can save a lot of time, but are costly and are out of reach for most DIYers.
If your OBD2 scanner won't start, check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are OK, it's likely that a fuse is blowing. This is the main cause of scan tool failure. It is often easy to fix the issue by replacing the fuse that was blown.
