fiat 500 new key Panda key fobs contain a transponder chip which sends signals to your car to unlock the doors or start the engine. However, the key fob may stop working due to a variety of causes.

The most frequent cause of key fob malfunction is the battery of the coin is dead. Other causes include water damage, malfunctioning receiver modules, and signal interference.

Dead Coin Battery

If your key fob battery has died, the first step is to replace it. Make use of a new button battery with identical in size, voltage and specifications as the previous one.

If the key fob has been exposed to water, for example a splash of rain or salt water on the beach, it will need to be cleaned before it can be used again. A paper towel soaked in isopropyl alcohol or electronic cleaner can be the solution.

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. Reprogramming the keyfob through an OBDII scan could help in these instances.

Water Damage

If your key fob has taken immersed in a pool or puddle or even a trip down the washing machine, you might have some water damage. It's generally 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 prior to installing a new battery.

There could be a problem with the module in the event that your key fob stops working after replacing the battery or reprogramming. You can find reprogramming procedures for all vehicles' remote key fobs on YouTube or in your owner's guide. 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 vehicle's system. This chip will stop sending and receiving signals to the car if it becomes damaged. Dropping the key fob could cause this, as could exposure to water. If your key fob stopped functioning due to exposure to water, you may be able to fix it if clean the chip with electronic cleaner or isopropyl ethanol.

However, if the key fob does not respond following cleaning, it is likely that the module is faulty and will need to be replaced. A damaged receiver can cause the key to not work. This usually happens due to electromagnetic interference.

Faulty electronic chip

The electronic chip in your key fob is an essential component of the anti-theft system in your vehicle. It sends out a signal the immobiliser unit in the vehicle to determine whether the key is valid. If the chip is damaged or broken, the car will not start.

A defective chip could be caused by interference from objects, bad weather or transmitters located near your vehicle. In this scenario, you will need a new key fob.

Contacts of the battery may be damaged.

The battery contacts of a key fob are very delicate and could be damaged by repeated 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 to keep out water. A splash of water or a light rain should be fine however, submerging them in salt water could harm the electronic chip.

The key fob has chips that communicate with the vehicle's immobilizer to allow it to begin it. The system utilizes the old red keys for older vehicles as well as the cryptocoding system used in newer cars. This chip needs to be replaced if damaged.

Poor 12 Volt Battery

A faulty battery may cause the key fob not to function. When this occurs the car's computer will not be able to recognize that the remote is inside the vehicle.

Test the battery with the help of a voltmeter to determine its capacity. A fully charged battery will display 12.6 volts. If the reading falls significantly the time is now to replace it.

Set an electrical load for a few moments on the battery to test its capacity. This will remove approximately 1% of the charge on the surface. Then, measure the voltage again. The greater the battery's capacity, the longer it can maintain its voltage. Ideally, it should remain at 12 volts or less for several minutes.

The radio signal is not working properly. Radio Signal

This is the most common reason for a fiat key cutting fob to stop sending signals to a car. The issue can be fixed by replacing the battery. It is crucial to buy an identical battery dimensions and voltage as the original.

Fobs endure a lot of abuse, but they're not impervious to destruction. The battery buttons and the contacts are fragile and are susceptible to being bent or broken with rough usage.

Other transmitters or objects operating on the same frequency could also interfere with a signal. For example, a light-control panel close to your home can send interference on the same frequency as key fobs use. This can affect the remote control of your car.

Faulty OBDII Scan Tool

There are a variety of reasons why scanner tools may not function. Some are more complicated than others.

Professional scan tools enable mechanics to examine the car's systems and run a range of self-tests. These are real time savers but they're also expensive, and out of the reach of most DIYers.

If your OBD2 scanner won't start examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are both present, it's likely that a fuse has failed. This is the most typical cause of scan tool failure. The easiest solution is to replace the fuse that has been blown.
