How To Get More Value With Your Fiat 500 Keys

Fiat 500 car keys Panda Key Fob Replacement

fiat key fobs Panda keyfobs are equipped with a transponder that transmits signals from the fob to the fiat car key cutting in order to unlock doors or turn on the motor. The fob might stop working due to a variety reasons.

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

Dead Coin Battery

Replace the battery in case your key fob has died. Use a brand new button battery with the same size, voltage and specification as the previous one.

If the key fob was exposed to water (such as saltwater or rain at the beach) it must be cleaned prior to being used again. The best way to do this is using a paper towel that has been soaked in isopropyl or electronic cleaner.

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

Water Damage

You might have water damage if your key fob was submerged in a puddle, pool or washing machine. It's usually possible to fix it by taking the batteries off and cleaning the circuit board with ruby alcohol. It is best to let the board completely dry prior to installing the battery.

If your key fob has stopped working, even after replacing the battery and changing the program, you could have a defective receiver module. You can find reprogramming instructions for most remote key fobs on YouTube or in the owner's guide. You could also try resetting the car's onboard computer using the OBDII scan tool.

Faulty Receiver Module

The key fob's chip is the chip that communicates with the vehicle's system. The chip will stop sending and receiving signals to the car when it is damaged. This could be due to dropping the key fob, or by water exposure. If the key fob is not working after exposure to water it could be possible to fix it by cleaning the chip using isopropyl alcohol, or electronic cleaner.

If the key fob does not respond to cleaning, it's likely that the module is in an issue and should be replaced. A defective receiver module could also cause the remote control key to stop functioning. This is usually caused by electromagnetic interference.

A malfunctioning electronic chip

The electronic chip in the key fob is a vital part of the anti-theft system in your car. It sends a signal the immobiliser unit in your car to determine whether or not the key is in fact valid. The car won't start in the event that the chip has been damaged.

A faulty chip may also be caused by interference from other objects, bad weather or transmitters close to your vehicle. In this scenario, you will need a new key fob.

Contacts to the battery are not working properly.

The battery contacts of a key fob can be damaged through heavy use. If they're bent or damaged, the fob will not send any signals to the receiver modules inside the vehicle.

Modern fobs have rubber seals to keep out water. A splash of water or a light rain is acceptable but submerging them into salt water could damage the electronic chip.

The key fob has chip that communicates with the immobilizer system of the vehicle in order to start it. This system uses crypto coding systems in modern vehicles and the older red key system used in older ones. The chip must be replaced if it's damaged.

Poor fiat 500 car keys 12 Volt Battery

A damaged battery can cause the key fob to cease working. If this happens, the car's computer system won't recognize that the remote is inside the vehicle.

Test the battery with the voltmeter before replacing it to determine its capacity. A fully charged battery will read 12.6 volts. If the reading falls significantly then it's time to replace it.

Install an electrical charge for a few seconds on the battery to test its capacity. This will take away approximately 1 percent of the charge on the surface. Then take another measurement of the voltage. The higher the capacity of the battery and the longer it can keep its voltage. Ideally, it should remain close to 12 volts several minutes.

Faulty Radio Signal

This is the most common reason for the key fob not sending signals to cars. The battery is able to be replaced to resolve this issue. But, it is essential to buy a new battery with the same size and voltage as the original.

Fobs aren't indestructible and are susceptible to damage. The battery buttons and the contacts are fragile and can be bent or damaged from rough use.

Other transmitters or objects operating on the same frequency could also interfere with the signal. A light-control panel in your home, for instance can interfere with key fobs using the same bandwidth. This could interfere with the remote control of your car.

Problems with OBDII Scan Tool

There are a variety of reasons why scanners don't perform. Certain are more complicated than others.

Professional scan tools enable mechanics to observe the car's network and perform various self-tests. These tools can save you 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 terminals 16 (scantool power) and 4 (chassis earth). If they're both in good shape it's possible that a fuse has failed. This is the most frequent reason for failures of the scanner. It is typically simple to fix the issue by replacing the fuse that has blown.
