fiat 500 duplicate key Panda key fobs contain an transponder chip that transmits an alert to your car to open the doors and start the engine. However, the fob could stop working due to a variety of causes.

The most commonly cited reason for key fob malfunction is an inoperable coin battery. Other causes include water damage an inoperative receiver module and signal interference.

Dead Coin Battery

Replace the battery if your key fob has died. Use a brand new button battery with identical in size, voltage and specifications as the original.

If the key fob was exposed to water (such as rain or saltwater at the beach) it should be cleaned before being used again. The best method 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 it is still not working it could be due to a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob by using an OBDII scan could help in these instances.

Water Damage

If your key fob took immersed in a puddle or pool or gone down the washing machine, it could have some water damage. It is usually possible to get it back to working by taking off the battery and then scrubbing the circuit board with isopropyl alcohol. It is best to let the board completely dry before installing the battery.

There could be a problem with the module when your key fob ceases working after replacing the battery or reprogramming. You can find information on reprogramming most vehicles' remote keys on YouTube or consult your owner's manual. You can also reset your computer in your car with the OBDII scanner tool.

Faulty Receiver Module

The key fob contains an electronic chip that communicates with the vehicle's system. If this chip becomes damaged, it cannot longer send and receive signals to the vehicle. This can be caused by dropping the key fob, or by water exposure. If your key fob has stopped functioning due to exposure to water, you may be able to fix it if clean the chip using electronic cleaner or isopropylethanol.

However, if the key fob continues to not respond following cleaning, you can be sure that the receiver module is not functioning properly and needs to be replaced. A malfunctioning receiver module could also cause the remote control key to stop working. This is typically caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip in your key fob plays an important role in the anti-theft security system of your car. It sends a signal the immobiliser unit inside your vehicle to tell it whether or not the key is valid. If the chip is damaged or broken, your car won't start.

A defective chip could be caused by interference from objects, bad weather or transmitters in the vicinity of your vehicle. In this scenario you'll need an entirely new key for fiat 500 key fob.

Contacts for the battery that are damaged

The battery contacts of the fob's key can be damaged by heavy usage. If they are broken or bent, the fob won't send any signals to the receiver modules in the car.

Modern fobs have rubber seals that keep out water. A splash of water or light rain is fine However, submerging them in saltwater can damage the chip's electronic components.

The key fob is equipped with chips that communicate with the vehicle's immobilizer system in order to start it. This system makes use of cryptocoding systems in vehicles that are more modern and the older red key system used in older ones. If the chip is damaged and needs to be replaced.

The 12 Volt Battery is faulty

A damaged battery could cause the key fob not to function. The car's computer will not recognize the remote when this happens.

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

Put an electrical load for a few seconds on the battery to test its capacity. This will remove approximately 1 percent of the charge on the surface. Then measure the voltage again. The better the battery's capacity is, the longer it will keep its voltage. The ideal scenario is to keep it at 12 volts or less for several minutes.

Radio Signal Faulty Radio Signal

This is the most typical reason for a key fob to stop sending signals to cars. The battery can be replaced to solve this problem. It is crucial to purchase a battery with the same dimensions and voltage as the original.

The buttons are not impervious to destruction and can be damaged by a lot. Contacts on batteries and buttons can be damaged through rough handling.

A signal may also be affected by other transmitters or objects who use the same frequency. For instance, a lighting control panel that is near your home could send interference over the same frequency that key fobs utilize. This could cause interference with the remote control of your car.

Incorrect OBDII Scan Tool

There are many reasons why a scanner could not work. Some are more complex than others.

Professional scan tools enable mechanics to observe the car's networks and run a range of self-tests. These are great time savers, however they are also extremely expensive and are out of the budget of many DIYers.

If your OBD2 scanner isn't turning on make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If all is fine there is a chance that a fuse has been blown. This is the most common reason for failures of the scanner. The easiest fix is to replace the fuse that has been blown.
