Fiat Panda Key Fob Replacement

fiat keys replacement Panda key fobs contain a transponder chip that sends an alert to your car to open the doors and start the engine. However, the key fob may stop working due to a variety of causes.

The most commonly cited reason for key fob malfunction is an inoperable coin battery. Other causes are water damage or a damaged 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 button cell battery that has the same voltage, size and specifications as your previous one.

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

If the key fob has not been exposed to water, but isn't working it could be due to an issue with the receiver module or an internal electronic chip. In these cases you can reprogramme the key fob with an OBDII scanner may aid.

Water Damage

You might have water damage to your key fob if it was submerged in a pool, puddle or washing machine. You can usually get it working again by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It is recommended to allow the device to completely dry prior to installing a battery.

There could be a problem with the module in the event that your remote stops working after replacing the battery or reprogramming. You can find the instructions for changing the programming of most remote keys on YouTube or consult the owner's manual. You could also try resetting the car's onboard computer using the OBDII scan tool.

Faulty Receiver Module

The key fob has a chip that communicates with the vehicle's system. If the chip is damaged, it will no longer transmit or receive signals to the vehicle. Dropping the key fob can cause this, as well as exposure to water. If your key fob isn't working due to water exposure it is possible fix the issue if you clean the chip using electronic cleaner or isopropyl alcohol.

However, if the key fob still does not respond even after cleaning it it is likely that the component is damaged and needs to be replaced. A damaged receiver module may also cause the remote control key to not function. This is usually caused by electromagnetic interference.

A defective electronic chip

The chip inside your key fob is a vital role in the anti-theft system of your car. It sends a message to the immobiliser in your car to tell it if the key is valid. If the chip is damaged or broken, the car won't start.

A defective chip can be caused by interference signals from objects such as weather conditions, objects or transmitters on the same frequency near your vehicle. In this case, you will need a new key fob.

Contacts of the battery may be damaged.

The battery contacts on the key fob are delicate and may be damaged with hard usage. If they are broken or bent, the fob will not be able to send any signals to the receiver modules inside the car.

Modern fobs come with rubber seals to keep out water. A splash of water or light rain is fine however, submerging them in saltwater can cause damage to the electronic chip.

The key fob is equipped with chips that communicate with the vehicle's immobilizer to allow it to allow it to start. The system utilizes the red keys of older vehicles, or the cryptocoding system found in newer vehicles. If this chip is faulty and needs to be replaced.

Faulty 12 Volt Batterie

A faulty battery can cause the remote to cease to function. The car's computer will not recognize the remote if this happens.

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

Set an electrical load for a few moments on the battery to test its capacity. This will take away about 1% of the charge on the surface. Then, measure the voltage once more. The greater the battery's capacity, the longer it can keep its voltage. Ideally, it should remain close to 12 volts several minutes.

The radio signal is not working properly. Radio Signal

This is the most common reason for the key fob to stop sending signals to vehicles. This issue can be fixed by replacing the battery. But, it is essential to choose a battery with the same size and voltage as the original one.

Fobs aren't impervious to damage and can withstand a lot. The battery buttons and contacts are brittle, so they can get bent or broken with rough use.

Other objects or transmitters using the same frequency could also disrupt the signal. For example, a light-control panel near your home may transmit interference on the same frequency that key fobs utilize. This can affect the remote control of your car.

Faulty OBDII scan tool

There are many reasons why a scan tool may not work. Certain are more complicated than others.

Professional scan tools allow a mechanic to observe the car's networks and run a variety of self-tests. These tools can save time, but are expensive and not accessible to most DIYers.

If your OBD2 scan tool doesn't turn on, check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If they're all fine, a fuse may have ruptured. This is among the most common causes of a scan tool failing. The most straightforward fix is to replace the fuse which has blown.
