fiat keys replacement Panda key fobs contain a transponder chip which sends a signal to your car to unlock the doors or start the engine. The fob might stop working for a variety.

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

Replace the battery if the key fob has failed. Use a new button cell battery that has exactly the same size, voltage, and specification as the old one.

If the key fob was exposed to water, like a splash of rain or salt water at the beach, it needs to be cleaned before it is able to be used again. A paper towel soaked in alcohol or electronic cleaner will help.

If the key fob isn't working despite being not exposed to water it could be due to a glitch in the receiver module, or even in the internal electronic chip. Reprogramming the keyfob by using an OBDII scan may assist in these situations.

Water Damage

There could be water damage if your key fob was submerged in a puddle, pool or washing machine. It is usually possible to fix it by taking out the batteries and cleaning the circuit board with ruby alcohol. It is a good idea to allow the fob to dry completely before putting in a new battery.

If your key fob stopped working even after replacing the battery and changing the program, you could have a faulty receiver module. You can find reprogramming instructions for all vehicles' remote key fobs on YouTube or in the owner's guide. You can also try resetting the car's onboard computer using the OBDII scan tool.

Faulty Receiver Module

The key fob contains a chip that communicates with the vehicle's system. If this chip becomes damaged, it cannot longer transmit and receive signals to the vehicle. Dropping the key fob can result in this, as can exposure to water. If the key fob has stopped working after exposure to water it may be possible to fix the issue by cleaning the chip using isopropyl alcohol or electronic cleaner.

If the key fob continues to not respond following cleaning, there is a good chance that the module is defective and will need to be replaced. A defective receiver module could also cause the remote control key to stop working. This is usually due to electromagnetic interference.

Electronic chip that is malfunctioning

The electronic chip that is in your key fob plays a crucial role in the anti-theft system in your car. It sends a message to the immobiliser in your car to tell it whether the key is genuine. Your car will not start in the event that the chip has been damaged.

A defective chip could be caused by interference from other objects, bad weather or transmitters located near your vehicle. In this instance you'll need an entirely new key fob.

Contacts with the battery may be damaged.

The battery contacts inside the key fob are delicate and could be damaged through repeated use. If they are damaged or bent, the fob will not be able to send any signals to the receiver modules inside the car.

Modern fobs come with rubber seals to keep out water. A splash of water or light rain is acceptable however, submerging them in salt water could harm the chip's electronic components.

The key fob houses a chip that communicates with the vehicle's immobilizer system to begin it. The system utilizes the old red keys for older vehicles or the cryptocoding system that is used in newer cars. This chip will have to be replaced if it's malfunctioning.

A faulty 12 Volt battery

A faulty battery can cause the key fob to stop working. When this happens the car's computer cannot recognize that the remote is in the vehicle.

Before replacing the battery, you should test it with a 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.

Place an electrical load for a few seconds on the battery to test its capacity. This will eliminate about 1% of the charge on the surface. Then take another measurement of the voltage. The better the battery's capacity, the longer it can keep its voltage. Ideal is to hold at or near 12 volts for several minutes.

Faulty Radio Signal

This is the most common reason for a key fob to stop sending signals to vehicles. The battery could be replaced to fix this issue. However, it is important to purchase a battery with the same size and voltage as the original.

The buttons are not impervious to destruction and can withstand a lot. The battery contacts and buttons are delicate and are susceptible to being bent or damaged by rough usage.

Other objects or transmitters using the same frequency can disrupt a signal. For instance, a lighting control panel that is near your home could transmit interference using the same frequency that key fobs utilize. This could interfere with the remote control of your car.

The tool is not working properly. OBDII scan tool

There are many reasons why scanner tools may not function. Some are more complicated than others.

Professional scan tools permit mechanics to look over the car's networks and perform a variety of self-tests. These tools can save you a lot of time, but are expensive and are out of reach for most DIYers.

If your OBD2 scanner won't turn on, check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're both in good shape, it's likely that a fuse is blowing. This is one of the most common causes of failures in the scan tool. The easiest fix is to replace the fuse which has blown.
