Fiat Panda Key Fob Replacement

fiat punto key replacement Panda key fobs contain a transponder chip which sends the signal to your vehicle to open the doors or start the engine. However, the key fob may stop working for several reasons.

A dead battery for the coin is the most frequent reason for the malfunction of a key fob. Other causes include water damage, malfunctioning receiver modules and signal interference.

Dead Coin Battery

Replace the battery if your key fob has failed. Choose a new button battery that is the same size, voltage and specification as the original.

If the key fob has been exposed to water, such as a splash of rain or salt water at the beach, it's going to need to be cleaned before it can be used again. The best way to do this is using an old towel soaked in isopropyl or an electronic cleaner.

If the key fob doesn't working despite not being exposed to water it could be due a malfunction in the receiver module or in the internal electronic chip. In these cases, reprogramming the key fob using an OBDII scanner can aid.

Water Damage

There could be water damage to your key fob if it was submerged in a puddle, pool or washing machine. It is usually possible to fix it by removing the batteries and cleaning the circuit board using rubbing alcohol. It is a good idea to let the fob dry completely before putting in a brand new battery.

If your key fob has stopped working even after replacing the battery and reconfiguring it, you may have a problem with the receiver module. You can find the instructions for the reprogramming of most remote keys on YouTube or in your owner's manual. You can also reset the computer of your car using the OBDII scanner tool.

Faulty Receiver Module

The key fob contains a chip which communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if damaged. This could be due to dropping the key fob or by exposure to water. If your key fob has stopped functioning due to exposure to water and you are unable to fix it by attempting to clean the chip with electronic cleaner or isopropyl alcohol.

However, if the key fob continues to not respond after cleaning it there is a good chance that the receiver module is not functioning properly and will need to be replaced. A damaged receiver module may also cause the remote control key to stop working. This is usually due to electromagnetic interference.

Faulty electronic chip

The electronic chip inside your key fob plays a vital role in the anti-theft system in your car. It transmits a signal to the immobiliser unit in your car to inform it whether the fiat 500 key replacement cost is in fact valid. If the chip is damaged or broken, your vehicle will not start.

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

Contacts to the battery are not working properly.

The battery contacts on the key fob could be damaged by heavy usage. If they're bent or broken, the fob won't send any signals to the receiver modules in the vehicle.

Modern fobs are constructed with rubber seals that keep out water. A splash of water or light rain should be fine However, submerging them in saltwater may cause damage to the chip's electronic components.

The key fob is equipped with chips that communicate with the vehicle's immobilizer system in order to begin it. This system utilizes cryptocoding systems in modern vehicles or the red key system for older models. This chip needs to be replaced if defective.

Faulty 12 Volt Battery

A damaged battery could cause the key fob to function. The car's system will not recognize the remote if this occurs.

Before you replace the battery, test it with a voltmeter to determine its capacity. A fully charged battery should read 12.6 volts. If the reading falls significantly, it is time to replace the battery.

To test the battery's capacity put an electrical load on it for a few minutes. This will eliminate about 1% of the surface charge. Then, measure the voltage again. The longer the battery can hold its voltage greater is its capacity. Ideally, it will remain at 12 volts or less for 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. The battery can be replaced to solve this issue. It is crucial to buy a battery with the same dimensions and voltage as the original.

Fobs can take a lot abuse, but they're not impervious to destruction. Battery contacts and buttons can be damaged by rough handling.

A signal can also be interrupted by other objects or transmitters that use the same frequency. A light-control panel in your home, for example could interfere with key fobs that have the same bandwidth. This could interfere with the remote control of your car.

Incorrect OBDII Scan Tool

There are many reasons scanners don't work. Certain are more complicated than others.

Professional scan tools permit mechanics to observe the car's networks and run a variety of self-tests. These can be real time savers but they can be expensive and are out of the budget of many DIYers.

If your OBD2 scan tool doesn't turn on, check voltage at the terminals 16 (scantool power) and 4 (chassis earth). If they're all fine the fuse could have failed. This is among the most common causes of failures in the scan tool. It is typically easy to fix the problem by replacing the blown fuse.
