5 Laws To Help In The Fiat 500 Keys Industry

Fiat Panda Key Fob Replacement

Fiat Panda keyfobs are equipped with a transponder that transmits signals from the fob to the car in order to unlock doors or start the motor. The fob could stop working due to a variety reasons.

The most frequent cause of key fob failure is the battery of the coin is dead. Other causes include water damage or a damaged module and interference signals.

Dead Coin Battery

If your key fob battery has failed, the initial step is to replace it. Use a button cell battery with the same voltage, size, and specifications as the previous one.

If the key fob was exposed to water (such as saltwater or rain at the beach) It must be cleaned before being used again. A paper towel soaked in isopropyl alcohol or electronic cleaner will do the trick.

If the key fob has not been exposed to water, but remains inoperable it could be because of a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob using an OBDII scan can help in these cases.

Water Damage

If your key fob has taken immersed in a pool or puddle or even a trip through the washing machine, you might have some water damage. It is 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 is best to let the circuit board completely dry before putting in the battery.

If your key fob isn't working, even after replacing the battery and changing the program, you could have a faulty receiver module. There are instructions for reprogramming most vehicles' remote keys on YouTube or refer to your owner's manual. You could also try resetting the car's computer onboard using the OBDII scan tool.

Faulty Receiver Module

The key fob's chip is a 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 due to exposure to water. If the key fob stopped working after exposure to water it may be possible to repair it by cleaning the chip with isopropyl alcohol or electronic cleaner.

If the key fob won't respond to cleaning, it's possible that the receiver module has an issue and should be replaced. A damaged receiver module may also cause the remote control key to stop working. This is usually caused by electromagnetic interference.

Faulty Electronic Chip

The chip inside your key fob is a vital part in the anti-theft security system in your car. It transmits a message the immobiliser inside your car to determine that the key is valid. If fiat 500 key fob is damaged or broken, your car won't start.

A damaged chip could be caused by interference caused by objects, bad weather or transmitters located near your vehicle. In this instance the replacement fob will be required.

Contacts for the battery that are damaged

The battery contacts of the fob's key can be damaged due to heavy use. If they're broken or bent, the fob will not transmit any signals to the receiver modules inside the car.

Modern fobs are equipped with rubber seals that keep out water. In the event of submerging them in water, even if it's just a light drizzle or splash can harm the chip's electronic circuit.

The key fob is equipped with an embedded chip that communicates to the immobilizer system of the vehicle, allowing it to start it. The system utilizes the red keys of older vehicles as well as the cryptocoding system found in modern vehicles. This chip will need to be replaced if defective.

A faulty 12 Volt battery

A faulty battery can cause the remote to stop working. If this happens, the car's computer system cannot recognize that the remote is in the vehicle.

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

Install an electrical charge for a few moments on the battery to determine its capacity. This will take away about 1 percent of the surface charge. Then, test the voltage once more. The longer a battery can hold its voltage, the better its capacity. Ideally, it should remain close to 12 volts for several minutes.

Faulty Radio Signal

This is the most frequent reason for keys not sending signals to cars. The issue can be fixed by replacing the battery. It is however important to select a replacement battery that has the same size and voltage as the original one.

Fobs can take a lot abuse, but they're not impervious to destruction. The battery buttons and the contacts are fragile which means they could be bent or damaged from excessive use.





Other transmitters or objects that use the same frequency could also interfere with a signal. A light-control panel in your home, for instance, may interfere with key fobs using the same frequency. This could affect the remote control in your car.

Afflicted OBDII Scan Tool

There are many reasons why scanner tools may not work. Some are more complex than others.

Professional scan tools enable mechanics to look over the car's network, and run various self-tests. These tools can help save time, but are expensive and out of reach for the majority of DIYers.

If your OBD2 scanner isn't turning on examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If both are in good condition the fuse could have blown. This is one of the most common causes of scan tool failure. It is often simple to fix the issue by replacing the blown fuse.
