The 3 Greatest Moments In Fiat 500 Keys History

Fiat Panda Key Fob Replacement

Fiat Panda keyfobs are equipped with a transponder which transmits an electronic signal from the fob to the car to open doors or turn on the motor. However, fiat 500 keys may stop working due to a variety of causes.

The most frequent cause of key fob failure is the battery of the coin is dead. Other causes include water damages as well as a defective module and interference signals.

Dead Coin Battery

Replace the battery if your key fob has died. Make use of a new button battery with exactly the same size, voltage and specifications as the old one.

If the key fob was exposed to water, for example a splash of rain or salt water at the beach, it needs to be cleaned before it can be used again. A paper towel soaked with isopropyl alcohol or electronic cleaner will do the trick.

If the key fob has not been exposed to water but remains inoperable it could be due to an issue with the receiver module or an internal electronic chip. Reprogramming the keyfob by using an OBDII scan can aid in these situations.

Water Damage

If your key fob's battery has taken a bath in the pool or puddle or even a trip through the washing machine, you may have some water damage. You can usually restore it's functionality by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It is best to let the board completely dry before putting in the battery.

If your key fob isn't working even after replacing the battery and reconfiguring it, you may have a problem with the receiver module. There are instructions for the reprogramming of most remote keys on YouTube or in the owner's manual. You can also reset the computer of your car using the OBDII scanner tool.

Faulty Receiver Module

The key fob has a chip which communicates with the vehicle's system. If the chip is damaged, it will no longer transmit and receive signals to the vehicle. Dropping the key fob could result in this, as can exposure to water. If your key fob has stopped working due to water exposure and you are unable to fix it by attempting to clean the chip using electronic cleaner or isopropyl alcohol.

If the key fob doesn't respond to cleaning, it's possible that the module has an issue and must be replaced. A faulty receiver can also cause the key to stop working. This is usually caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside your key fob is a vital function in the anti-theft security system in your car. It transmits a message to the immobiliser inside your car to tell it if the key is valid. Your car won't start when the chip is damaged.

A damaged chip could be caused by interference from objects, bad weather or transmitters near your vehicle. In this case, you will need an entirely new key fob.

Contacts to the battery are not working properly.

The battery contacts on the key fob are delicate and can get damaged through repeated use. If they're bent or broken, the fob won't transmit any signals to receiver modules inside the vehicle.

Modern fobs are made with rubber seals in order to keep out water. Immersing them in water, even if just small splash or drizzle can harm the chip's electronic components.

The key fob houses chips that communicate with the vehicle's immobilizer system to start it. The system relies on cryptocoding systems in modern vehicles, or the old red key system for older models. If this chip is faulty, it will need to be replaced.

Poor 12 Volt Battery

A damaged battery can cause the remote to cease working. The car's system will not recognize the remote if this occurs.

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

Install an electrical charge for a short period of time on the battery to test its capacity. This will eliminate 1% of the surface charges. After that, take the voltage again. The longer the battery can keep its voltage steady and the higher its capacity. It should be close to 12 volts for several minutes.

Problems with Radio Signal

This is the main cause of a key fob that ceases to send signals to the car. The battery is able to be replaced to resolve this issue. It is crucial to purchase a battery with the same dimensions and voltage as the original.

Fobs take a lot of abuse, and they aren't indestructible. The battery buttons and contacts are brittle which means they could be bent or damaged from excessive use.

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

Afflicted OBDII scan tool

There are many reasons a scanner tool may not work. Some are more complicated than others.

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

If your OBD2 scan tool isn't turning on, make sure you check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition it's possible that a fuse has blown. This is the most common reason for a scan tool to fail. It is generally simple to fix the issue by replacing the fuse blowing up.
