Fiat Panda Key Fob Replacement

Fiat Panda key fobs contain an transponder chip that transmits signals to your car to open the doors and start the engine. However, the fob could be inoperable due to various reasons.

A dead coin battery is the most common cause of malfunctioning keys. Other causes are water damage as well as a defective module and interference signals.

Dead Coin Battery

If your key fob battery has gone out of service, the first thing to do is replace it. Make use of a new button battery that has the same voltage, size and specification as the old one.

If the key fob was exposed to water (such as rain or saltwater at the beach), it must be cleaned before being used again. The best method is to use a paper towel soaked with isopropyl or electronic cleaner.

If the key fob doesn't working despite not being exposed to water, it could be due to a glitch in the receiver module or internal electronic chip. Reprogramming the keyfob with an OBDII scan may aid in these situations.

Water Damage

If your key fob took submerged in a puddle or pool or gone down the washing machine, you could be suffering some water damage. It's possible to get it back in working order by taking the batteries off and cleaning the circuit board with rubbing alcohol. It is recommended to let the board completely dry prior to installing a battery.

If your key fob stopped working even after replacing the battery and changing the program, you could have a faulty receiver module. You can find reprogramming procedures for most remote key fobs on YouTube or in the owner's guide. You can also reset the computer of your car using the OBDII scanner tool.

Faulty Receiver Module

The key fob's chip is a chip that connects to the car's system. fiat 500 key fob will stop sending and receiving signals to the car when it is damaged. The key fob being dropped can cause this, as can water exposure. If the key fob stopped working after exposure to water it could be possible to fix it by cleaning the chip using isopropyl ethanol or electronic cleaner.

However, if the key fob does not respond after cleaning it, you can be sure that the component is damaged and will need to be replaced. A faulty receiver can also cause the key to stop working. This is often caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip in your key fob plays a vital function in the anti-theft security system in your car. It sends a signal to the immobiliser inside your car that tells it whether the key is legitimate. Your car won't start in the event that the chip has been damaged.

A faulty chip may also be caused by interference from objects, bad weather or transmitters in the vicinity of your vehicle. In this scenario you'll need an entirely new key fob.


Contacts with the battery may be damaged.

The battery contacts on a key fob can be damaged by excessive usage. If they're bent, or damaged, the fob will not transmit any signals to receiver modules in the vehicle.

Modern fobs are equipped with rubber seals to keep out water. A splash of water or light rain is fine However, submerging them in saltwater may harm the electronic chip.

The key fob contains chip that communicates with the immobilizer system of the vehicle in order to start it. This system uses crypto coding systems in newer vehicles as well as the traditional red key system used in older ones. If this chip is faulty it will have to be replaced.

A faulty 12 Volt battery

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

Test the battery with the help of a voltmeter to determine its capacity. A fully charged battery will display 12.6 volts. If the reading falls significantly then it's time to replace the battery.

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 take away 1% of the surface charges. After that, take the voltage once more. The better the battery's capacity, the longer it can keep its voltage. The ideal scenario is to keep it close to 12 volts several minutes.

The radio signal is not working properly. Radio Signal

This is the most common reason behind a key fob that stops sending signals to the car. The battery can be replaced to fix this issue. It is essential to purchase batteries that have the same dimensions and voltage as the original.

Fobs aren't indestructible and can be damaged by a lot. The battery contacts and buttons could be damaged through rough handling.

The signal could also be disrupted by other transmitters or objects that operate on the same frequency. For instance, a light control panel that is near your home could send interference over the same frequency as key fobs utilize. This could interfere with the remote control of your car.

Problems with OBDII Scan Tool

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

Professional scan tools let mechanics to observe the car's network and run various self-tests. These are great time savers but they can be expensive, out of the range of most DIYers.

If your OBD2 scanner doesn't work examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're all fine, a fuse may have been blown. This is the main reason for failure of the scan tool. The most straightforward fix is to replace the fuse that is blowing up.
