15 Terms Everyone Is In The Fiat 500 Keys Industry Should Know

Fiat Panda Key Fob replacement key fiat 500

fiat abarth key punto remote key replacement (more info) Panda keyfobs are equipped with a transponder that transmits a signal from the fob to the car that allows it to unlock doors or start the motor. The fob could stop working for a variety.

A dead coin battery is the most common reason for key fob malfunctions. Other reasons include water damage, an inoperative receiver module, and signal interference.

Dead Coin Battery

Replace the battery if your key fob is dead. Make use of a new button battery that is the same voltage, size and specification as the previous one.

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

If the key fob is not working despite not being exposed to water it could be due to a malfunction in the receiver module or in the internal electronic chip. Reprogramming the keyfob through an OBDII scan can help in these cases.

Water Damage

It is possible to get water damage to your key fob if it was submerged in a pool, puddle or washing machine. It's usually possible to be able to get it back up and running by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It's a good idea to let the fob dry completely before putting in a brand new battery.

You could have a damaged module if your key fob stops working after replacing the battery or changing the programming. You can find instructions for changing the programming of most remote keys on YouTube or in your owner's manual. You can also try resetting the car's onboard computer with the OBDII scan tool.

Faulty Receiver Module

The key fob is equipped with an electronic chip that communicates with the vehicle's system. If the chip is damaged, it cannot longer transmit and receive signals to the vehicle. This can be caused by dropping the key fob, or by water exposure. If the key fob stopped working after water exposure it is possible to fix it by cleaning the chip using isopropyl alcohol, or electronic cleaner.

If the key fob won't respond to cleaning, it is possible that the component has a fault and needs to be replaced. A defective receiver module could also cause the remote control key to stop working. This is typically caused by electromagnetic interference.

Faulty Electronic Chip

The chip inside your key fob plays an important part in the anti-theft security system of your car. It transmits a message the immobiliser inside your car to determine if the key is valid. Your car will not start if the chip is damaged.

A malfunctioning chip could be caused by interference signals from objects, bad weather conditions or transmitters on the same frequency as your vehicle. In this scenario you'll need a new key fob.

Contacts of the battery may be damaged.

The battery contacts in the key fob are delicate and could be damaged with hard usage. If they are broken or bent, the fob will not be able to send any signals to the receiver modules in the car.

Modern fobs are designed with rubber seals in order to keep out water. A splash of water or light rain is fine, but submerging them in salt water could cause damage to the chip's electronic components.

The key fob contains the chip that connects to the vehicle's immobilizer to allow it to begin it. The system uses the red keys of older vehicles as well as the cryptocoding system that is used in newer vehicles. If the chip is damaged it must be replaced.

Problematic 12 Volt Battery

A malfunctioning battery could cause the key fob not to function. When this occurs the car's computer cannot recognize that the remote is in the vehicle.

Before you replace the battery, test it with the voltmeter to determine its capacity. A fully charged battery will read 12.6 volts. If the reading falls dramatically then it's time to replace the battery.

To test a battery's capacity to determine its capacity, put an electric load on it for a few minutes. This will remove 1percent of the surface charges. Then, you can measure the voltage. The longer a battery can hold its voltage, the better its capacity. The ideal is to keep it close to 12 volts over several minutes.

Problems with Radio Signal

This is the main cause of a key fob that stops sending signals to the car. The battery could be replaced to fix this issue. It is essential to purchase batteries that have the same dimensions and voltage as the original.

Fobs are subject to a lot of punishment, and aren't indestructible. Contacts on batteries and buttons can be damaged by rough handling.

Other transmitters or objects that use the same frequency can also disrupt a signal. For instance, a light-control panel close to your home can send interference over the same frequency as key fobs utilize. This could cause interference with the remote control in your car.

Incorrect OBDII scan tool

There are a number of reasons why a scanner could not work. Some are more complex than others.

Professional scan tools allow mechanics to monitor the car's network and run a range of self-tests. They can be huge time savers, but they can also be very expensive and are out of the budget of many DIYers.

If your OBD2 scanner won't turn on, check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are both present it's possible that a fuse has failed. This is the most typical reason for failures of the scanner. It is generally easy to fix the issue by replacing the fuse that has blown.
