10 Things We All Are Hateful About Fiat 500 Keys

Fiat Panda Key Fob Replacement

fiat key Panda keyfobs are equipped with a transponder which transmits signals from the fob to the car that allows it to unlock doors or start the motor. However, the fob can stop working due to a variety of causes.

A dead coin battery is the most frequent cause of malfunctioning keys. Other causes are water damage, a faulty receiver module, and signal interference.

Dead Coin Battery

Replace the battery in case your key fob has gone out of service. Choose a button battery with the same voltage, size, and specification as your old one.

If the key fob was exposed to water (such as saltwater or rain at the beach) it should be cleaned prior to using it again. The trick is to use the paper towel and soak it in isopropyl or electronic cleaner.

If the key fob has not been exposed to water, but isn't working it could be due to an issue with the receiver module or an internal electronic chip. In these situations it is possible to re-programme the fiat 500 replacement key cost fob using an OBDII scanner may help.

Water Damage

If your key fob has taken immersed in a pool or puddle or even a trip down the wash machine, you could be suffering some water damage. You can usually get it working again by removing the battery and scrubbing the circuit board with isopropyl alcohol. It's best to let the circuit board completely dry before installing batteries.

If your key fob stopped working even after replacing the battery and programming it again, you might have a problem with the receiver module. You can find the instructions for reprograming the majority of remote keys on YouTube, or consult your owner's manual. You could also try resetting the car's onboard computer using the OBDII scan tool.

Faulty Receiver Module

The key fob is equipped with a chip that communicates with the vehicle's system. If this chip becomes damaged, it will no longer be able to send or receive signals to the vehicle. This can be caused by dropping the key fob or by water exposure. If the key fob you have purchased has stopped functioning due to exposure to water, you may be able fix the issue if you clean the chip with electronic cleaner or isopropyl ethanol.

However, if the key fob does not respond after cleaning it you can be sure that the module is defective and needs to be replaced. A damaged receiver can cause the key to cease to function. This is typically caused by electromagnetic interference.

Electronic chip that is malfunctioning

The chip that is embedded in the key fob is a vital component of the anti-theft systems in your car. It transmits a signal to the immobiliser unit inside your car to inform it whether the key is in fact valid. The car will not start in the event that the chip has been damaged.

A faulty chip may also be caused by interference from other objects, weather conditions or transmitters in the vicinity of your vehicle. In this situation you'll need a new key fob.

Contacts for the battery that are damaged

The battery contacts inside a key fob are very delicate and could be damaged by repeated use. If they are bent, or broken, the fob won't transmit any signals to receiver modules in the vehicle.

Modern fobs feature rubber seals that block out water. A splash of water or light rain is fine however, submerging them in saltwater may damage the chip's electronic components.

The key fob comes with chip that communicates with the immobilizer system of the vehicle to begin it. It uses the old red keys that were used in older vehicles as well as the cryptocoding system that is used in newer vehicles. If the chip is damaged it will have to be replaced.

Problematic 12 Volt Battery

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

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

Set an electrical load for a few seconds on the battery to gauge its capacity. This will remove 1percent of the surface charges. Then take another measurement of the voltage. The longer the battery is able to keep its voltage steady and the higher its capacity. It is ideal to maintain close to 12 volts during several minutes.

Problems with Radio Signal

This is the most frequent reason for the key fob to stop sending signals to vehicles. The issue can be fixed by replacing the battery. However, it is crucial to purchase a battery that is the same size and voltage as the original one.

Fobs are not indestructible and can be damaged by a lot. Battery contacts and buttons can be damaged through rough handling.

Other transmitters or objects operating on the same frequency could also interfere with the signal. For instance, a light-control panel close to your home can send interference on the same bandwidth that key fobs use. This can interfere with your car's remote control.

Problems with OBDII Scan Tool

There are a number of reasons why a scan tool could not function. 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 they're expensive and out of reach for most DIYers.

If your OBD2 scan tool isn't turning on, check voltage at the terminals 16 (scantool power) and 4 (chassis earth). If these are both present it's likely that a fuse has failed. This is one of the most frequent reasons for failure of the scanner. It is usually simple to fix the issue by replacing the fuse blowing up.
