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

Fiat Panda Key Fob Replacement

fiat punto key replacement Panda key fobs contain a transponder chip which sends the signal to your vehicle to open the doors and start the engine. The fob may stop working for a variety.

The most common reason for key fob malfunction is a dead coin battery. Other reasons include water damage, malfunctioning receiver modules, and signal interference.

Dead Coin Battery

If your key fob's battery has failed, the initial thing to do is replace it. Choose a new button battery with exactly the same size, voltage and specification like the previous one.

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

If the key fob isn't working even though it is not exposed to water, it could be due to a malfunction in the receiver module, or even in the internal electronic chip. In these cases it is possible that reprogramming the key fob using an OBDII scanner may assist.

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 get it working by taking the batteries off and cleaning the circuit board with ruby alcohol. It's best to allow the fob to dry completely before putting in a brand new battery.

If your key fob has stopped working, even after replacing the battery and changing the program, you could have a malfunctioning receiver module. You can find instructions for changing the programming of most remote keys on YouTube or in your owner's manual. You can also reset the car's computer using the OBDII scanner tool.

Faulty Receiver Module

The key fob is equipped with a chip that connects to the car's system. This chip will stop sending and receiving signals to the car if damaged. This could be due to dropping the key fob, or by water exposure. If your key fob isn't functioning due to exposure to water it is possible fix the issue if you clean the chip with electronic cleaner or isopropylethanol.

If the key fob doesn't respond to cleaning, it's possible that the module has an issue and should be replaced. A faulty receiver can also cause the key to stop working. This is usually due to electromagnetic interference.

Faulty Electronic Chip

The electronic chip inside the key fob is an essential part of the anti-theft system in your vehicle. It sends a signal to the immobiliser inside your car that tells it 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, bad weather conditions or transmitters on the same frequency as your vehicle. In this scenario it is likely that a new fob would be required.

Faulty battery contacts

The battery contacts on the fob's battery can be damaged due to heavy use. If they're bent or broken, the fob won't transmit any signals to receiver modules in the vehicle.

Modern fobs feature rubber seals that keep out water. Immersing them in water, even if it's just small splash or drizzle could harm the chip's electronic circuit.

The key fob contains the chip that connects to the vehicle's immobilizer system to allow it to start. The system is based on the old red keys in older vehicles or the cryptocoding system that is used in modern vehicles. The chip must be replaced if it's defective.

The 12 Volt Battery is faulty

A faulty battery may cause the key fob not to function. The car's computer will not recognize the remote when this occurs.

Before replacing the battery, test it by using a an voltmeter for determining its capacity. A fully charged battery should display 12.6 volts. If the reading falls dramatically then it's time to replace the battery.

Put an electrical load for a few moments on the battery to test its capacity. This will take off about 1 percent of the charge on the surface. After that, take the voltage once more. The higher the capacity of the battery, the longer it can keep its voltage. Ideally, it should remain close to 12 volts for several minutes.

Radio Signal Faulty Radio Signal

This is the most common reason for keys not sending signals to the car. This issue can be resolved by replacing the battery. However, it is important to purchase a battery that has the same voltage and size as the original one.

Fobs aren't impervious to damage and are susceptible to damage. Battery contacts and buttons can be damaged through rough handling.

Other transmitters or objects that use the same frequency could also interfere with a signal. For instance, a light-control panel near your home may send interference on the same bandwidth that key fobs utilize. This can affect the remote control of your car.

Faulty OBDII Scan Tool

There are many reasons why a scan tool could not function. Some are more complicated than others.

Professional scan tools let mechanics to monitor the car's network and run various self-tests. These tools can save you a lot of time, but they're expensive and are out of reach for most DIYers.

If your OBD2 scanner won't turn on make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are both present it's likely that a fuse is blowing. This is one of the most common causes of a scan tool failing. It is generally easy to fix the issue by replacing the fuse that has blown.
