Fiat Panda key fobs contain transponder chips that send the signal to your vehicle to unlock the doors or start the engine. The fob could stop working due to a variety reasons.

The most frequent cause of key fob failure is a dead coin battery. Other causes include water damage the receiver module is defective, and signal interference.

Dead Coin Battery

If the battery in your key fob has failed, the initial thing to do is replace it. Use a brand new button battery that has exactly the same size, voltage and specifications like the previous one.

If the key fob has been exposed to water, like a splash of rain or salt water on the beach, it's going to need to be cleaned before it can 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 not being exposed water, it could be due a malfunction in the receiver module or an internal electronic chip. In these situations, reprogramming the key fob with an OBDII scanner might aid.

Water Damage

If your key fob has taken an immersion in the pool or puddle, or taken a trip through the washing machine, you might have some water damage. You can usually get it back to working by removing the battery and scrubbing the circuit board with isopropyl alcohol. It is recommended to let the fob completely dry before putting in a battery.

If your key fob stopped working, even after replacing the battery and reconfiguring it, you may have a faulty receiver module. There are reprogramming guidelines for the majority of vehicles' remote key fobs on YouTube or in your owner's guide. You could also try resetting the car's onboard computer with the OBDII scan tool.

Faulty Receiver Module

The key fob is equipped with a chip that communicates with the vehicle's system. The chip will stop sending and receiving signals to the car if damaged. This can be caused by dropping the key fob or due to exposure to water. If the key fob is not working after water exposure it may be possible to repair the issue by cleaning or cleaning the chip with isopropyl alcohol, or electronic cleaner.

If the key fob won't respond to cleaning, it is possible that the module has an issue and should be replaced. A malfunctioning receiver module could also cause the remote control key to stop functioning. This is usually due to electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside your key fob is an important part of the anti-theft system in your vehicle. It sends a signal to the immobiliser in your car to determine whether the key is legitimate. If the chip is damaged or broken, your car will not start.

A malfunctioning chip can be caused by interference from other objects, bad weather or transmitters near your vehicle. In this situation it is likely that a new fob would be needed.

Faulty battery contacts

The battery contacts of the fob's key can be damaged by excessive usage. If they're bent or broken, the fob won't transmit any signals to receiver modules inside the vehicle.

Modern fobs are made with rubber seals that keep out water. In the event of submerging them in water, even if it's just a light drizzle or splash can harm the chip's electronic components.

The key fob contains an electronic chip that communicates with the vehicle's immobilizer system to activate it. The system uses the old red keys that were used in older vehicles, or the crypto coding system in newer vehicles. This chip will have to be replaced if malfunctioning.

Problematic 12 Volt Battery

A faulty battery may cause the key fob not to work. The car's system will not recognize the remote if this happens.

Test the battery using the voltmeter before replacing it to determine its capacity. A fully charged battery should display 12.6 volts. If the reading decreases significantly then it's time to replace it.

Set an electrical load for a few seconds on the battery to check its capacity. This will remove one percent of the surface charges. Then, test the voltage once more. The greater the battery's capacity and the longer it can keep its voltage. The ideal is to keep it close to 12 volts during several minutes.

Radio Signal Faulty Radio Signal

This is the most typical reason for a key fob that ceases to send signals to the car. The issue can be fixed by replacing the battery. It is important to buy an identical battery dimensions and voltage as the original.

Fobs are not indestructible and can take a lot. The battery buttons and contacts are brittle and are susceptible to being bent or broken with the force of.

Other objects or transmitters using the same frequency could also disrupt the signal. A light-control panel at your home, for instance, may interfere with key fobs that have the same frequency. This could interfere with your car's remote control.

Problems with OBDII Scan Tool

There are many reasons why a scanner tool may not function. Some are more complex than others.

Professional scan tools let mechanics to monitor the car's network and perform various self-tests. They can be huge time savers but they can also be very expensive, and out of the range of 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 these are OK it's likely that a fuse has failed. This is one of the most frequent reasons for failure of the scanner. It is usually easy to fix the problem by replacing the fuse that was blown.
