Fiat key Fob not Working Panda keyfobs are equipped with a transponder, which sends an indication from the fob to the car in order to unlock doors or turn on the motor. The fob can stop functioning due to a variety of reasons.

The most commonly cited reason for key fob failure is a dead coin battery. Other causes include water damage as well as a defective module and interference signals.

Dead Coin Battery

Replace the battery in case your fiat 500 spare key fob has died. Choose a button battery with the same voltage, size and specifications as the old one.

If the key fob was exposed to water, like a splash of rain or salt water at the beach, it will have to be cleaned before it is able to be used again. A paper towel soaked with isopropyl alcohol or electronic cleaner can do the trick.

If the key fob isn't working despite not being 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 can help in these cases.

Water Damage

If your key fob took immersed in a puddle or pool or walked down the wash machine, it could have some water damage. It's generally possible to fix it by taking the batteries off and cleaning the circuit board using rubbing alcohol. It's a good idea 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 problem with the receiver module. You can find reprogramming instructions for most vehicles' remote key fobs on YouTube or in the owner's manual. You can also try resetting the car's onboard computer using the OBDII scan tool.

Faulty Receiver Module

The key fob has a chip which communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if it becomes damaged. The key fob being dropped can cause this, as can exposure to water. If the key fob has stopped working after exposure to water it is possible to repair the issue by cleaning or cleaning the chip with isopropyl alcohol or an electronic cleaner.

If the key fob continues to not respond after cleaning it then it is likely that the module is faulty and needs to be replaced. A defective receiver can cause the key to stop working. This usually happens due to electromagnetic interference.

Faulty electronic chip

The electronic chip in your key fob plays a crucial part in the anti-theft security system in your car. It sends a message to the immobiliser inside your car to determine if the key is valid. If the chip is damaged or broken, your car won't start.

A faulty chip can also be caused by interference signals from objects, bad weather conditions or transmitters on the same frequency in close proximity to your vehicle. In this scenario, you will need an entirely new key fob.

Faulty Battery Contacts

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

Modern fobs feature rubber seals that keep out water. Submerging them in water even if it's only a light drizzle or splash, can damage the chip's electronic circuit.

The key fob contains chip that communicates with the immobilizer system of the vehicle to begin it. The system utilizes the old red keys for older vehicles as well as the cryptocoding system found in modern vehicles. This chip will need to be changed if it is damaged.

Problematic 12 Volt Battery

A faulty battery can cause the remote to stop working. The car's computer may not recognize the remote if this occurs.

Before you replace the battery, you should test it with a an voltmeter to gauge its capacity. A fully charged battery should read 12.6 volts. If the reading falls significantly then it's time to replace it.

To test a battery's capacity, place an electrical load on it for a few minutes. This will take away about 1 percent of the surface charge. After that, take the voltage once more. The longer a battery can hold its voltage and the higher its capacity. Ideally, it should remain at 12 volts or less for several minutes.

Problems with Radio Signal

This is the most typical reason for the key fob to stop sending signals to vehicles. The battery can be replaced to solve this issue. It is important to buy a battery that has the same dimensions and voltage as the original.

The buttons are not impervious to destruction and can be damaged by a lot. The battery buttons and contacts are delicate and are susceptible to being bent or broken with the force of.

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

Afflicted OBDII Scan Tool

There are a variety of reasons why scanners may not work. Some are more complicated than others.

Professional scan tools enable a mechanic observe the car's networks and run various self-tests. These are great time-savers, but they are also extremely expensive, and beyond the budget of many DIYers.

If your OBD2 scanner isn't turning on examine the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If these are both present the chances are that a fuse has blown. This is among the most frequent causes of failures in the scan tool. It is often easy to fix the problem by replacing the fuse that was blown.
