Fiat Bravo Key Panda Key Fob Replacement

fiat 500 locked keys in car Panda keyfobs are equipped with a transponder which transmits an electronic signal from the fob to the car in order to unlock doors or start the motor. The fob might stop working due to a variety of reasons.

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

Dead Coin Battery

Replace the battery if the key fob has failed. 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 must be cleaned before being used again. A paper towel soaked with isopropyl alcohol or electronic cleaner can help.

If the fiat key programming fob doesn't working even though it is not exposed to water, it could be due to a problem in the receiver module, or even in the internal electronic chip. Reprogramming the keyfob through an OBDII scan may assist in these situations.

Water Damage

If your key fob took submerged in a puddle or pool, or taken a trip down the washing machine, you could be suffering some water damage. It is usually possible to fix it by taking the batteries off and cleaning the circuit board with ruby alcohol. It's a good idea to allow the fob to dry completely before putting in a brand new fiat 500 key battery.

There could be a problem with the module when your key fob ceases working after replacing the battery or changing the programming. Reprogramming instructions are available for most remote key fobs on YouTube or in the owner's manual. You can also reset your computer of your vehicle using the OBDII scanner tool.

Faulty Receiver Module

The fiat 500x key fob fob has an electronic chip that communicates with the vehicle's system. If the chip is damaged, it will be unable to longer transmit and receive signals to the vehicle. This could be due to dropping the key fob, or due to exposure to water. If the key fob stopped working after exposure to water it could be possible to repair it by cleaning the chip using isopropyl alcohol or an electronic cleaner.

If the key fob does not respond to cleaning, it's possible that the receiver module has an issue and should be replaced. A defective receiver can cause the key to stop working. This is typically caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside the key fob is an essential element of the anti-theft device in your car. It sends a message to the immobiliser inside your car to tell it if the key is valid. If the chip is damaged or broken, your vehicle will not start.

A faulty chip may also be caused by interference from other objects, weather conditions or transmitters located near your vehicle. In this instance an upgrade to the fob will be required.

Faulty Battery Contacts

The battery contacts of the key fob are fragile and are susceptible to damage with hard usage. If they are bent, or damaged, the fob will not send any signals to receiver modules in the vehicle.

Modern fobs are designed with rubber seals to keep out water. A splash of water or a light rain should be fine however, submerging them in saltwater may harm the chip's electronic components.

The key fob has chips that communicate with the vehicle's immobilizer in order to allow it to start. The system utilizes the old red keys in older vehicles as well as the cryptocoding system used in newer vehicles. This chip needs to be changed if it is malfunctioning.

Problems with 12 Volt Batteries

A defective battery can cause the remote to stop working. When this happens the car's computer will not be able to recognize that the remote is inside the vehicle.

Test the battery using the voltmeter before replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading drops significantly it's time to change it.

To determine the capacity of a battery put an electrical load on it for a couple of minutes. This will take away about 1 percent of the surface charge. Then, you can measure the voltage. The higher the capacity of the battery and the longer it can maintain its voltage. Ideal is that it stays close to 12 volts for several minutes.

Problems with Radio Signal

This is the main reason for a key fob that ceases to send signals to the car. The battery can be replaced to fix this issue. But, it is essential to select a replacement battery with the same size and voltage as the original one.

Fobs can take a lot abuse, but they're not impervious to destruction. The battery buttons and contacts are brittle and can be bent or broken with excessive use.

Other objects or transmitters using the same frequency can interfere with the signal. A light-control panel in your home, for example can interfere with key fobs that have the same frequency. This can affect the fiat ducato remote key replacement control of your car.

Incorrect OBDII scan tool

There are many reasons why a scanner might not work. Some are more complex than others.

Professional scan tools let mechanics to observe the car's networks and run various self-tests. These tools can save a lot of time, but are costly and out of reach for the majority of DIYers.

If your OBD2 scan tool fails to turn on, test the voltage at terminals 16 (scantool power) and 4 (chassis earth). If they are all OK there is a chance that a fuse has been blown. This is among the most common causes of a scan tool failing. The most straightforward fix is to replace the fuse that has been blown.
