Fiat Panda Key Fob Replacement

fiat panda key fob replacement Panda key fobs contain transponder chips that send signals to your car to open the doors or start the engine. However, the fob can stop working for several reasons.

A dead coin battery is the most common reason for the malfunction of a key fob. Other causes are water damage as well as a defective module and interference signals.

Dead Coin Battery

Replace the battery if your key fob has died. Choose a new button battery that has the same size, voltage and specifications as the old one.

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

If the key fob doesn't working despite not being exposed water, it could be due to a malfunction in the receiver module, or even in the internal electronic chip. Reprogramming the keyfob through an OBDII scan could help in these cases.

Water Damage

You could have water damage to your key fob if it was submerged in a puddle, pool or washing machine. It's usually possible to get it back to working by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It is best to allow the device to completely dry before putting in a battery.

You could have a damaged module when your key fob ceases working after replacing the battery or updating. There are reprogramming guidelines for all vehicles' remote key fobs on YouTube or in the owner's guide. You can also reset your car's computer using the OBDII scanner tool.

Faulty Receiver Module

The key fob has a chip which communicates with the vehicle's system. If this chip becomes damaged, it will be unable to longer send and receive signals to the vehicle. This could be due to dropping the key fob or through exposure to water. If the key fob is not functioning after exposure to water, it is possible to fix the issue by cleaning the chip using isopropyl alcohol or an electronic cleaner.

However, if the key fob continues to not respond following cleaning, it is likely that the module is defective and will require to be replaced. A faulty receiver module can also cause the remote control key to stop working. This is usually due to electromagnetic interference.

Faulty Electronic Chip

The chip that is embedded in the key fob is an essential element of the anti-theft device in your car. It transmits a signal to the immobiliser device in your car to determine whether or not the key is valid. Your car will not start in the event that the chip has been damaged.

A faulty chip can also be caused by interference signals from other objects such as weather conditions, objects or transmitters operating on the same frequency close to your vehicle. In this case you'll need an entirely new key fob.

Contacts for the battery that are damaged

The battery contacts on the key fob are delicate and could be damaged by repeated use. If they're bent, or broken, the fob won't send any signals to the receiver modules inside the vehicle.

Modern fobs are constructed with rubber seals in order to keep out water. A splash of water or light rain should be fine but submerging them into salt water could damage the chip's electronic components.

The key fob houses the chip that connects to the vehicle's immobilizer system to allow it to start. The system relies on cryptocoding systems in newer vehicles as well as the traditional red key system in older models. The chip must be replaced if faulty.

Faulty 12 Volt Batterie

A damaged battery could cause the key fob not to work. When this occurs the car's computer won't recognize that the remote is within the vehicle.

Before you replace the battery, test it with an voltmeter to gauge its capacity. A fully charged battery will display 12.6 volts. If the reading drops dramatically it's time to change it.

Place an electrical load for a short period of time on the battery to gauge its capacity. This will eliminate 1percent of the surface charges. Then measure the voltage again. The longer a battery is able to keep its voltage steady, the better its capacity. It is ideal to maintain close to 12 volts over several minutes.

The radio signal is not working properly. Radio Signal

This is the most typical reason for the key fob to stop sending signals to a car. The issue can be fixed by replacing the battery. It is important to buy a battery with the same dimensions and voltage as the original.

Fobs can take a lot abuse, and they aren't impervious to destruction. Contacts on batteries and buttons can be damaged through rough handling.

A signal can also be disrupted by other transmitters or objects that use the same frequency. For instance, a light-control panel in your home could send interference over the same bandwidth that key fobs utilize. This could affect the remote control in your car.

Faulty OBDII Scan Tool

There are many reasons why scanner tools may not perform. Some are more complex than others.

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

If your OBD2 scanner doesn't work, check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are OK it's likely that a fuse has failed. This is the main reason for failures of the scanner. It is generally easy to fix the issue by replacing the fuse blowing up.
