Pay Attention: Watch Out For How Fiat 500 Keys Is Taking Over And What Can We Do About It

Fiat Panda Key Fob Replacement

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

A dead battery for the coin is the most common cause of the malfunction of a key fob. Other causes include water damage a faulty receiver module, and signal interference.

Dead Coin Battery

Replace the battery if the key fob has gone out of service. Make use of a new button battery with the same size, voltage and specifications like the previous one.

If the key fob was exposed to water, like a splash of rain or salt water at the beach, it's going to need to be cleaned before it is able to be used again. A paper towel soaked in alcohol or electronic cleaner can be the solution.

If the key fob doesn't working despite not being exposed to water, it could be due a malfunction in the receiver module, or even in the internal electronic chip. In these situations it is possible that reprogramming the key fob with an OBDII scanner might assist.

Water Damage

It is possible to get water damage if your key fob was submerged in a puddle, pool or washing machine. You can usually get it back to working by taking the battery off and cleaning the circuit board with isopropyl alcohol. It is best to let the board completely dry prior to installing the battery.

You could have a damaged module when your key fob ceases working after replacing the battery or reprogramming. You can find reprogramming procedures for most vehicles' remote key fobs on YouTube or in your owner's guide. You can also try resetting the car's onboard computer using the OBDII scan tool.

Faulty Receiver Module

The key fob's chip is a chip which communicates with the vehicle's system. If the chip is damaged, it cannot longer send and receive signals to the vehicle. The key fob being dropped can cause this, as can exposure to water. If the key fob stopped working after exposure to water it could be possible to repair the issue by cleaning or cleaning the chip with isopropyl alcohol or electronic cleaner.

However, if the key fob does not respond following cleaning, it is likely that the module is faulty and will require to be replaced. A defective receiver module could also cause the remote control key to stop functioning. This is usually caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip in the key fob is a crucial part of the anti-theft system in your vehicle. It transmits a signal to the immobiliser unit in your car to inform it whether or not the key is genuine. Your car will not start in the event that the chip is damaged.

A defective chip could be caused by interference caused by objects, bad weather or transmitters located near your vehicle. In this case, a new fob will be needed.

Contacts for the battery that are damaged

The battery contacts on a key fob can be damaged by excessive usage. If they're damaged or bent, the fob will not transmit any signals to the receiver modules inside the car.

Modern fobs have rubber seals that block out water. Immersing them in water, even if it is just a light drizzle or splash, can damage the electronic chip.

The key fob is equipped with chips that communicate with the vehicle's immobilizer system in order to begin it. The system uses the old red keys for older vehicles, or the cryptocoding system that is used in the latest vehicles. This chip needs to be replaced if malfunctioning.

The 12 Volt Battery is faulty

A damaged battery could cause the key fob to work. The car's computer won't recognize the remote when this happens.

Test the battery using an voltmeter prior to replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading drops significantly the time is now to replace it.

To determine the capacity of a battery, place an electrical load on it for a couple of minutes. This will take off approximately 1 percent of the charge on the surface. Then, measure the voltage again. The greater the battery's capacity is, the longer it will maintain its voltage. It is ideal to maintain close to 12 volts for several minutes.

Faulty Radio Signal

This is the most common reason behind a key fob that stops sending signals to the car. The battery is able to be replaced to resolve this problem. It is important to buy an identical battery dimensions and voltage as the original.

Fobs aren't indestructible and can take a lot. The battery buttons and the contacts are fragile which means they could be bent or broken with the force of.

A signal can also be affected by other objects or transmitters that operate on the same frequency. For example, a light-control panel close to your home can send interference on the same frequency as key fobs utilize. This could interfere with your car's remote control.

Faulty OBDII scan tool

There are a variety of reasons why a scanner tool may not perform. Some are more complicated than others.

Professional scan tools let mechanics to monitor the car's network and run various self-tests. These tools can save a lot of time, but are expensive and not accessible to the majority of DIYers.

If your OBD2 scan tool isn't turning on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If all is fine there is a chance that a fuse has failed. This is one of the most frequent causes of failures in the scan tool. It is often easy to fix the problem by replacing the fuse blowing up.
