Fiat Panda Key Fob Replacement

Fiat Panda keyfobs are equipped with a transponder, which sends signals from the fob to the car to unlock doors or turn on the motor. The fob can stop functioning for a variety of reasons.

The most commonly cited reason for key fob failure is an inoperable coin battery. Other causes are water damage or a damaged module and interference signals.

Dead Coin Battery

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

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

If the key fob hasn't been exposed to water, but isn't working it could be an issue with the receiver module or an internal electronic chip. In these cases, reprogramming the key fob with an OBDII scanner could help.

If your key fob has gotten submerged in a pool or puddle, or taken a trip down the washing machine, you could be suffering some water damage. It's possible to fix it by removing the batteries and cleaning the circuit board using rubbing alcohol. It's best to allow the fob to dry completely before putting in a brand new battery.

It could be that you have a defective module in the event that your remote stops working after replacing the battery or changing the programming. You can find reprogramming procedures for most vehicles' remote key fobs on YouTube or in the owner's guide. You can also reset your computer in your car with the OBDII scanner tool.

Faulty Receiver Module

The key fob has the chip that communicates the vehicle's system. If the chip is damaged, it will be unable to longer send and receive signals to the vehicle. Dropping the key fob could result in this, as can exposure to water. If your key fob stopped working due to water exposure, you may be able fix the issue if you clean the chip using electronic cleaner or isopropylethanol.

However, if the key fob still does not respond following cleaning, there is a good chance that the module is defective and will need to be replaced. A damaged receiver can cause the key to not work. This is typically caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside the key fob is an important element of the anti-theft device in your car. It sends a signal the immobiliser device in the vehicle to determine whether or not the key is genuine. The car will not start when the chip is damaged.

A faulty chip may also be caused by interference from other objects, bad weather or transmitters close to your vehicle. In this situation you'll need an entirely new key fob.

Faulty Battery Contacts

The battery contacts inside a key fob are very delicate and could be damaged with hard usage. If they're bent, or broken, the fob won't transmit any signals to receiver modules inside the vehicle.

Modern fobs are constructed with rubber seals that keep out water. A splash of water or a light rain should be fine but submerging them into salt water could damage the electronic chip.

The key fob has an electronic chip that communicates with the vehicle's immobilizer in order to activate it. The system uses the old red keys in older vehicles as well as the cryptocoding system used in modern vehicles. If the chip is damaged and needs to be replaced.

A faulty 12 Volt battery

A defective battery can cause the remote to cease to function. The car's system will not recognize the remote when this occurs.

Before replacing the battery, you should test it with a a voltmeter 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.

Place an electrical load for a short time on the battery to test its capacity. This will remove 1percent of the surface charges. After that, take the voltage once more. The higher the capacity of the battery is, the longer it will keep its voltage. The ideal scenario is to keep it close to 12 volts for several minutes.

The radio signal is not working properly. Radio Signal

This is the main reason behind a key fob that ceases to send signals to the car. This issue can be resolved by replacing the battery. But, it is essential to purchase a battery that is the same voltage and size as the original.

Fobs can take a lot abuse, but they're also not indestructible. The battery buttons and contacts are brittle and are susceptible to being bent or damaged by excessive use.

The signal could also be impacted by other transmitters or objects that operate on the same frequency. A light control panel in your home, for example can interfere with key fobs which use the same bandwidth. This could interfere with the remote control in your car.

The tool is not working properly. OBDII scan tool


There are many reasons scanner tools may not work. Some are more complicated than others.

Professional scan tools let a mechanic observe the car's network and run various self-tests. These are real time savers but they can be expensive, and beyond the range of most DIYers.

If your OBD2 scanner doesn't work make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If both are in good condition there is a chance that a fuse has failed. This is one of the most frequent causes of failures in the scan tool. The easiest fix is to replace the fuse that has been blown.
