Fiat Panda Key Fob Replacement
Fiat Panda key fobs contain an transponder chip that transmits an alert to your car to open the doors or start the engine. The fob may stop working for a variety.
A dead battery for the coin is the most frequent cause of a key fob malfunction. Other causes include water damage, malfunctioning receiver modules, and signal interference.
Dead Coin Battery
If your key fob battery is dead, the first step is to replace it. Choose a button battery with the same voltage, size, and specifications as the old one.
If the key fob was exposed to water (such as saltwater or rain at the beach) it should be cleaned before using again. A paper towel soaked in isopropyl alcohol or electronic cleaner will help.
If the key fob hasn't been exposed to water but remains inoperable it could be an issue with the receiver module or an internal electronic chip. In these instances it is possible to re-programme the key fob with an OBDII scanner might help.
Water Damage
You might have water damage to your key fob if it was submerged in a puddle, pool or washing machine. It's possible to repair it by getting rid of the batteries and cleaning the circuit board with rubbing alcohol. It is recommended to let the fob completely dry before putting in batteries.
You may have a faulty module in the event that your remote stops working after replacing the battery or reprogramming. There are reprogramming guidelines for the majority of vehicles' remote key fobs on YouTube or in the owner's guide. You can also reset your car's computer using the OBDII scanner tool.
Faulty Receiver Module
The key fob contains an electronic chip that communicates with the vehicle's system. If this chip becomes damaged, it cannot longer transmit or receive signals to the vehicle. Dropping the key fob could cause this, as could exposure to water. If your key fob has stopped working due to water exposure it is possible to fix it if you clean the chip using electronic cleaner or isopropylethanol.
However, if the key fob still does not respond after cleaning it, there is a good chance that the module is defective and needs to be replaced. A faulty receiver module can also cause the remote control key to stop working. This is typically caused by electromagnetic interference.
Faulty Electronic Chip
The chip inside your key fob is a vital function in the anti-theft security system of your car. It sends out a signal the immobiliser unit inside your vehicle to tell it whether the key is valid. Your car will not start in the event that the chip is damaged.
A damaged chip could be caused by interference from other objects, weather conditions or transmitters close to your vehicle. In this scenario the replacement fob will be required.

The battery contacts of the key fob are fragile and are susceptible to damage by repeated use. If they're bent, or damaged, the fob will not transmit any signals to receiver modules inside the vehicle.
Modern fobs are designed with rubber seals to keep out water. A splash of water or a light rain is fine, but 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 to allow it to start. It uses the old red keys for older vehicles, or the crypto coding system in modern vehicles. This chip will need to be replaced if malfunctioning.
Faulty 12 Volt Batterie
A defective battery can cause the key fob to work. When this happens the car's computer will not be able to recognize that the remote is within the vehicle.
Before replacing the battery, you should test it with a an voltmeter to gauge its capacity. A fully charged battery should read 12.6 volts. If the reading drops significantly, it's time to replace it.
To determine the capacity of a battery test the battery's capacity by placing an electrical load on it for a few minutes. This will take off about 1 percent of the surface charge. Then measure the voltage again. The higher the capacity of the battery is, the longer it will maintain its voltage. It is ideal to maintain at or near 12 volts for several minutes.
The radio signal is not working properly. Radio Signal
This is the most typical reason for keys not sending signals to vehicles. The battery can be replaced to fix this problem. However, it is crucial to select a replacement battery that is the same voltage and size as the original one.
Fobs endure a lot of abuse, but they're also not impervious to destruction. The battery contacts and buttons could be damaged through rough handling.
Other transmitters or objects that use the same frequency could also interfere with the signal. A light-control system in your home, for example can interfere with key fobs that use the same frequency. This can interfere with the remote control of your car.
Incorrect OBDII scan tool
There are many reasons why a scan tool may not work. Certain are more complicated than others.
Professional scan tools let mechanics to observe the car's network, and run various self-tests. These can be real time savers, but they can be expensive, out of the range of most DIYers.
If your OBD2 scan tool isn't turning on, make sure you check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If these are OK it's likely that a fuse has been blown. This is among the most common causes of scan tool failure. It is typically easy to fix the issue by replacing the fuse blowing up.
