15 Unquestionably Good Reasons To Be Loving Fiat 500 Keys
Fiat Panda Key Fob Replacement
Fiat Panda keyfobs are equipped with a transponder that sends an electronic signal from the fob to the car in order to unlock doors or start the motor. The fob could stop working due to a variety reasons.
A dead coin battery is the most frequent reason for a key fob malfunction. Other causes are water damage, a faulty receiver module and signal interference.
Dead Coin Battery
Replace the battery if your key fob has failed. Choose a button battery with the same voltage, size and specification as your old one.
If the key fob was exposed to water (such as rain or saltwater at the beach) it must be cleaned prior to using it again. A paper towel soaked with isopropyl alcohol or electronic cleaner will help.
If the key fob has not been exposed to water but still does not work, there may be an issue with the receiver module or an internal electronic chip. In these cases it is possible that reprogramming the key fob with an OBDII scanner may aid.

If your key fob has gotten immersed in a pool or puddle or even a trip down the wash machine, you could be suffering some water damage. It is usually possible to be able to get it back up and running by taking the battery off and cleaning the circuit board with isopropyl alcohol. It's best to let the board completely dry before installing the battery.
If your key fob isn't working even after replacing the battery and reconfiguring it, you may have a malfunctioning receiver module. You can find information on the reprogramming of most remote keys on YouTube, or consult the owner's manual. You can also reset the car's computer using the OBDII scanner tool.
Faulty Receiver Module
The key fob is equipped with an electronic chip that communicates with the vehicle's system. If the chip is damaged, it cannot longer transmit or receive signals to the vehicle. This can be caused by dropping the key fob, or due to exposure to water. If your key fob stopped working due to exposure to water and you are unable to fix it if you clean the chip using electronic cleaner or isopropyl alcohol.
However, if the key fob does not respond after cleaning it then it is likely that the module is defective and needs to be replaced. A damaged receiver module may also cause the remote control key to cease functioning. This is often caused by electromagnetic interference.
Electronic chip that is malfunctioning
The electronic chip inside your key fob is a vital component of the anti-theft systems in your vehicle. It sends a signal the immobiliser unit in your car to determine whether the key is valid. If the chip is damaged or broken, your vehicle will not start.
A damaged chip could be caused by interference signals from objects such as weather conditions, objects or transmitters operating on the same frequency as your vehicle. In this situation you'll need a new key fob.
Contacts for the battery that are damaged
The battery contacts on the key fob could be damaged by heavy usage. If they're damaged or bent, the fob will not transmit any signals to the receiver modules inside the car.
Modern fobs have rubber seals that keep out water. A splash of water or a light rain should be fine but submerging them into salt water could cause damage to the chip's electronic components.
The key fob contains a chip which communicates with the immobilizer system of the vehicle, allowing it to start it. This system utilizes cryptocoding systems in modern vehicles as well as the traditional red key system used in older ones. If the chip is defective it will have to be replaced.
Poor 12 Volt Battery
A faulty battery may cause the key fob not to work. The car's computer will not recognize the remote if this occurs.
Test the battery using an voltmeter prior to replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading falls dramatically then it's time to replace the battery.
Install an electrical charge for a few moments on the battery to test its capacity. This will remove approximately 1 percent of the charge on the surface. After that, measure the voltage. The greater the battery's capacity and the longer it can keep its voltage. Ideal is to hold close to 12 volts during several minutes.
Problems with Radio Signal
This is the main reason for a keyfob that ceases to send signals to the car. This issue can be fixed by replacing the battery. It is crucial to purchase batteries that have the same voltage and dimensions as the original.
The buttons are not impervious to destruction and can be damaged by a lot. The battery buttons and contacts are brittle, so they can get bent or damaged from the force of.
Other transmitters or objects that use the same frequency may also disrupt the signal. A light-control panel at your home, for example could interfere with key fobs which use the same frequency. This could affect the remote control in your car.
Afflicted OBDII Scan Tool
There are a variety of reasons why a scanner tool may not perform. Certain are more complicated than others.
Professional scan tools allow a mechanic to examine the car's systems and conduct a variety self-tests. These are great time-savers, but they can be expensive, and beyond the budget of many DIYers.
If your OBD2 scan tool won't power on, make sure you check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If these are OK the chances are that a fuse has been blown. This is the most common cause of scan tool failure. The simple fix is usually to replace the fuse that is blowing up.
