11 "Faux Pas" That Are Actually Acceptable To Create With Your Fiat 500 Keys

Fiat Panda Key Fob Replacement

Fiat Panda key fobs contain a transponder chip which sends a signal to your car to unlock the doors or start the engine. However, the fob can be inoperable due to various reasons.

A dead coin battery is the most frequent reason for a key fob malfunction. Other causes include water damage an inoperative receiver module and signal interference.

Dead Coin Battery

If your key fob battery is dead, the first step is to replace it. Use a button cell battery that has the same voltage, size, and specifications as the old one.

If the key fob has been exposed to water, like a splash of rain or salt water at the beach, it will need to be cleaned before it can be used again. The best way to do this is using the paper towel and soak it in isopropyl or an electronic cleaner.

If the key fob has not been exposed to water but it is still not working it could be because of an issue with the receiver module or an internal electronic chip. In these cases it is possible that reprogramming the key fob with an OBDII scanner might assist.

Water Damage

If your key fob's battery has taken submerged in a puddle or pool or gone down the wash machine, it could have some water damage. It's usually possible to get it working again by taking the battery off and cleaning the circuit board with isopropyl alcohol. It's best to let the circuit board completely dry prior to installing the battery.

If your key fob has stopped working even after replacing the battery and programming it again, you might have a malfunctioning receiver module. Reprogramming helpful site are available for all vehicles' remote key fobs on YouTube or in the owner's manual. You could also try resetting the car's onboard computer by using the OBDII scan tool.

Faulty Receiver Module

The key fob's chip is an electronic chip that communicates with the car's system. If the chip is damaged, it cannot longer transmit or receive signals to the vehicle. The key fob being dropped can result in this, as can water exposure. If the key fob stops working after exposure to water it may be possible to repair it by cleaning the chip with isopropyl ethanol or electronic cleaner.

If the key fob does not respond to cleaning, it is likely that the module is in an issue and must be replaced. A damaged receiver can cause the key to cease to function. This usually happens due to electromagnetic interference.

Electronic chip that is malfunctioning

The electronic chip inside your key fob plays an important function in the anti-theft security system of your vehicle. It sends a signal to the immobiliser unit in the vehicle to determine whether the key is genuine. Your car will not start in the event that the chip has been damaged.

A malfunctioning chip could be caused by interference signals from other objects or weather conditions that are bad, or transmitters on the same frequency close to your car. In this scenario, you will need an entirely new key fob.

Faulty battery contacts

The battery contacts on the key fob are delicate and could be damaged by repeated use. If they're broken or bent, the fob won't send any signals to the receiver modules in the car.

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

The key fob is equipped with a chip that communicates with the vehicle's immobilizer system in order to activate it. It uses the red keys of older vehicles, or the cryptocoding system that is used in newer cars. If this chip is faulty and needs to be replaced.

Poor 12 Volt Battery

A faulty battery may cause the key fob to function. When this happens the car's computer will not recognize that the remote is in the vehicle.

Before replacing the battery, test it by using a a voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading drops dramatically it's time to change it.

To test a battery's capacity put an electrical load on it for a couple of minutes. This will remove 1percent of the surface charges. Then, measure the voltage again. The longer a battery can hold its voltage more effectively, the greater its capacity. Ideal is to hold close to 12 volts during several minutes.

Radio Signal Faulty Radio Signal

This is the most common reason for the key fob to stop sending signals to a car. This problem can be solved by replacing the battery. However, it is important to purchase a battery that is the same voltage and size as the original.

Fobs take a lot of abuse, but they're not indestructible. The battery contacts and buttons could be damaged through rough handling.

Other transmitters or objects operating on the same frequency may also disrupt the signal. For instance, a light control panel near your home may transmit interference using the same frequency as key fobs use. This can affect the remote control of your car.

Faulty OBDII Scan Tool

There are many reasons why a scanner could not work. Some are more complicated than others.

Professional scan tools enable mechanics to monitor the car's network, and run various self-tests. These are great time-savers, but they are also extremely expensive, and beyond the reach of most DIYers.

If your OBD2 scan tool doesn't turn on, make sure you check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If all is fine, a fuse may have been blown. This is among the most frequent causes of scan tool failure. The simple fix is usually to replace the fuse which has blown.
