How To Get More Results Out Of Your Fiat 500 Keys
Fiat Panda Key Fob Replacement

Fiat Panda keyfobs are equipped with a transponder that transmits an indication from the fob to the car that allows it to unlock doors or start the motor. The fob might stop working due to a variety reasons.

A dead battery for the coin is the most common cause of malfunctioning keys. Other causes include water damage an inoperative receiver module, and signal interference.

Dead Coin Battery

If the battery in your key fob has gone out of service, the first step is to replace it. Make use of a button cell battery that has the same voltage, size, and specifications as your previous one.

If the key fob has been exposed to water, like a splash of rain or salt water on the beach, it needs to be cleaned before it can be used again. The best solution is to use a paper towel soaked with isopropyl or electronic cleaner.

If the key fob isn't working despite not being exposed water it could be due a malfunction in the receiver module or internal electronic chip. Reprogramming the keyfob using an OBDII scan could aid in these situations.

thekeylab.co.uk might have water damage if your key fob was submerged in a pool, puddle or washing machine. You can usually be able to get it back up and running 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.

You could have a damaged module in the event that your remote stops working after replacing the battery or changing the programming. You can find the instructions for reprogramming most vehicles' remote keys on YouTube, or consult the owner's manual. You could also try resetting the car's computer onboard using the OBDII scan tool.

Faulty Receiver Module

The key fob contains the chip that communicates the vehicle's system. If this chip becomes damaged, it will be unable to longer be able to send or receive signals to the vehicle. This could be due to dropping the key fob or by water exposure. If your key fob has stopped working due to water exposure or water exposure, you might be able to fix it if you clean the chip using electronic cleaner or isopropyl ethanol.

If the key fob won't respond to cleaning, it is possible that the receiver module has an issue and must be replaced. A damaged receiver can cause the key to stop working. This is typically caused by electromagnetic interference.

Electronic chip that is malfunctioning


The electronic chip inside your key fob plays an important function in the anti-theft security system of your car. It sends a signal to the immobiliser inside your car to determine if the key is valid. If the chip is damaged or broken, the car won't start.

A malfunctioning chip can be caused by interference from other objects, bad weather or transmitters near your vehicle. In this case the replacement fob will be required.

Contacts of the battery may be damaged.

The battery contacts inside the key fob are fragile and are susceptible to damage with hard usage. If they are damaged or bent, the key fob will not be able to send any signals to the receiver modules inside the car.

Modern fobs are constructed with rubber seals in order to keep out water. Submerging them in water even if it's only a light drizzle or splash, can damage the chip's electronic circuit.

The key fob is equipped with chips that communicate with the vehicle's immobilizer system to start it. This system utilizes cryptocoding systems in newer vehicles and the older red key system in older ones. This chip will have to be replaced if it's damaged.

Faulty 12 Volt Battery

A faulty battery can cause the key fob to stop working. The car's computer won't recognize the remote if this happens.

Before you replace the battery, test it by using a the voltmeter to determine its capacity. A fully charged battery will read 12.6 volts. If the reading falls significantly, it's time to replace it.

To test the battery's power test the battery's capacity by placing an electrical load on it for a few minutes. This will take away about 1% of the surface charge. Then take another measurement of the voltage. The longer a battery is able to keep its voltage steady greater is its capacity. Ideally, it should remain close to 12 volts for several minutes.

The radio signal is not working properly. Radio Signal

This is the most frequent reason for the key fob not sending signals to vehicles. This problem can be solved by replacing the battery. But, it is essential to purchase a battery with the same size and voltage as the original one.

The buttons are not impervious to destruction and are susceptible to damage. The battery buttons and the contacts are fragile and are susceptible to being bent or broken with excessive use.

A signal may also be affected by other objects or transmitters that operate on the same frequency. For instance, a lighting control panel close to your home can transmit interference using the same frequency as key fobs utilize. This could interfere with the remote control in your car.

Faulty OBDII Scan Tool

There are a number of reasons why a scanner could not work. Certain are more complicated than others.

Professional scan tools allow a mechanic to look over the car's networks and conduct a variety self-tests. These tools can save time, but they are costly and not accessible to most DIYers.

If your OBD2 scan tool isn't turning on, make sure you check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If they're all fine the fuse could have ruptured. This is among the most common causes of a scan tool failing. It is often simple to fix the issue by replacing the blown fuse.
