Fiat Panda keyfobs are equipped with a transponder, which sends an electronic signal from the fob to the car in order to unlock doors or start the motor. The fob may stop working due to a variety reasons.

The most frequent cause of key fob failure is an inoperable coin battery. Other causes are water damage, an inoperative receiver module and signal interference.

Dead Coin Battery

Replace the battery in case your key fob has died. Use a brand new button battery that has the same size, voltage, and specification as the previous 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 that has been soaked in isopropyl alcohol or electronic cleaner can do the trick.

If the key fob has not been exposed to water but it is still not working it could be because of an issue with the receiver module or an internal electronic chip. In these instances it is possible to re-programme the key fob using an OBDII scanner could aid.

Water Damage

If your key fob has gotten submerged in a pool or puddle or even a trip down the wash machine, you may have some water damage. It's usually possible to get it back to working by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It's best to allow the fob to dry completely before putting in a new battery.

It could be that you have a defective module if your key fob stops working after replacing the battery or replacing it with. You can find reprogramming instructions for most remote key fobs on YouTube or in the owner's manual. You can also reset your car's computer using the OBDII scanner tool.

Faulty Receiver Module

The key fob contains a chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if damaged. This can be caused by dropping the key fob or by exposure to water. If the key fob is not functioning after exposure to water, it could be possible to fix it by cleaning the chip using isopropyl ethanol or electronic cleaner.

If the key fob does not respond to cleaning, it's possible that the component has an issue and must be replaced. A malfunctioning receiver could cause the key to cease to function. This is usually due to electromagnetic interference.

Electronic chip that is malfunctioning

The chip that is embedded in the key fob is a vital component of the anti-theft system in your vehicle. It transmits a signal to the immobiliser unit inside the vehicle to determine whether or not the key is valid. If the chip is damaged or broken, your car won't start.

A faulty chip may also be caused by interference caused by objects, bad weather or transmitters located near your vehicle. In this case, a new fob will be required.

Contacts for the battery that are defective

The battery contacts of the fob's battery can be damaged by heavy usage. If they're bent or damaged, the fob will not transmit any signals to receiver modules inside the vehicle.

Modern fobs come with rubber seals that keep out water. Immersing them in water, even if it is just small splash or drizzle could harm the chip's electronic circuit.

The key fob contains chips that communicate with the vehicle's immobilizer system to begin it. This system makes use of cryptocoding systems in vehicles that are more modern and the older red key system in older models. If the chip is defective it must be replaced.

Faulty 12 Volt Batterie

A faulty battery may cause the key fob not to work. If this happens the car's computer won't recognize that the remote is inside the vehicle.

Before you replace the battery, test it using a an voltmeter for determining its capacity. A fully charged battery should read 12.6 volts. If the reading falls significantly it is time to replace the battery.

To test the battery's capacity put an electrical load on it for a few minutes. This will remove approximately 1% of the charge on the surface. Then measure the voltage again. The greater the battery's capacity, the longer it can keep its voltage. Ideally, it should remain at or near 12 volts for several minutes.

Problems with Radio Signal

This is the main reason for the key fob not sending signals to the car. This problem can be solved by replacing the battery. It is however important to choose a battery that has the same voltage and size as the original one.

The buttons are not impervious to destruction and can be damaged by a lot. The battery contacts and buttons could be damaged through rough handling.

Other transmitters or objects using the same frequency can interfere with the signal. A light-control system in your home, for instance can interfere with key fobs using the same bandwidth. This can interfere with your car's remote control.

Incorrect OBDII scan tool

There are many reasons scanners don't work. Certain are more complicated than others.

Professional scan tools enable mechanics to observe the car's network and run various self-tests. These are real time-savers, but they're also expensive, out of the range of most DIYers.

If your OBD2 scanner isn't turning on examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're both in good shape the chances are that a fuse has blown. This is among the most common reasons for failure of the scanner. It is generally simple to fix the issue by replacing the fuse blowing up.
