Fiat Panda key fobs contain a transponder chip that sends a signal to your car to unlock the doors or start the engine. However, the key fob may stop working due to a variety of causes.

The most commonly cited reason for key fob malfunction is an inoperable coin battery. Other reasons include water damage, a faulty receiver module, and signal interference.

Dead Coin Battery

Replace the battery if your key fob has gone out of service. Choose a button battery that has the same voltage, size and specifications as the previous one.

If the key fob was exposed to water (such as saltwater or rain at the beach), it must be cleaned prior to being used again. A paper towel soaked with isopropyl alcohol or electronic cleaner can help.

If the key fob hasn't been exposed to water, but it is still not working, there may 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 can assist.

Water Damage

There could be water damage to your key fob if it was submerged in a puddle, pool or washing machine. It is usually possible to get it working by getting rid of the batteries and cleaning the circuit board using ruby alcohol. It's a good idea to let the fob dry completely before installing a new battery.

You could have a damaged module in the event that your key fob stops working after replacing the battery or updating. You can find reprogramming procedures for the majority of vehicles' remote key fobs on YouTube or in your owner's guide. You can also try resetting the car's onboard computer by using the OBDII scan tool.

Faulty Receiver Module

The key fob has the chip that communicates with the car's system. The chip will stop sending and receiving signals to the car when it is damaged. A key fob falling off can result in this, as can exposure to water. If the key fob stops working after exposure to water, it is possible to repair it by cleaning the chip with isopropyl ethanol or electronic cleaner.

If the key fob doesn't respond to cleaning, it is possible that the receiver module has an issue and should be replaced. A faulty receiver module can also cause the remote control key to stop working. This is typically caused by electromagnetic interference.

Electronic chip that is malfunctioning

The electronic chip that is in your key fob plays an important role in the anti-theft system of your vehicle. It sends a signal to the immobiliser in your car to determine whether the key is legitimate. Your car will not start in the event that the chip has been damaged.

A faulty chip can also be caused by interference signals from other objects, bad weather conditions or transmitters on the same frequency close to your vehicle. In this case an upgrade to the fob will be needed.

Contacts for the battery that are defective

The battery contacts of the key fob could be damaged through heavy use. If they're damaged or bent, the key fob will not be able to send any signals to the receiver modules inside the car.

Modern fobs come with rubber seals to keep out water. In the event of submerging them in water, even if it's only the slightest splash or drizzle could damage the chip's electronic components.

The key fob is equipped with an electronic chip that communicates with the immobilizer system of the vehicle in order to start it. This system makes use of cryptocoding systems in newer vehicles as well as the traditional red key system used in older models. If this chip is faulty it will have to be replaced.

Problematic 12 Volt Battery

A faulty battery can cause the remote to cease working. When this happens, the car's computer system will not be able to recognize that the remote is inside the vehicle.

Before you replace the battery, test it with the voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading drops dramatically it's time to change it.

To determine the capacity of a battery test the battery's capacity by placing an electrical load on it for a couple of minutes. This will eliminate 1percent of the charges. Then, measure the voltage again. The longer a battery is able to hold its voltage, the better its capacity. It is ideal to maintain close to 12 volts during several minutes.

Faulty Radio Signal

This is the main reason for the key fob to stop sending signals to vehicles. The issue can be fixed by replacing the battery. But, it is essential to buy a new battery with the same voltage and size as the original.

Fobs can take a lot abuse, and they aren't impervious to destruction. The battery contacts and buttons could be damaged by rough handling.

A signal can also be disrupted by other objects or transmitters who use the same frequency. For instance, a light-control panel that is near your home could transmit interference using the same bandwidth that key fobs use. This can affect the remote control of your car.

Afflicted OBDII scan tool

There are a variety of reasons why scanners may not perform. Some are more complicated than others.

Professional scan tools let mechanics to monitor the car's networks and run various self-tests. These tools can save a lot of time, but are costly and are out of reach for the majority of DIYers.

If your OBD2 scanner isn't turning on, check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If both are in good condition the chances are that a fuse has failed. This is the most frequent reason for failures of the scanner. The most straightforward fix is to replace the fuse that has been blown.
