fiat key fob not working Panda key fobs contain transponder chips that send an alert to your car to open the doors and start the engine. However, the fob may stop working due to a variety of causes.

The most common cause of key fob malfunction is an inoperable coin battery. Other reasons include water damage, a faulty receiver module and signal interference.

Dead Coin Battery

If your key fob battery has gone out of service, the first thing to do is replace it. Choose a button battery with the same voltage, size, and specifications as the old 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 alcohol or electronic cleaner will help.

If the key fob is not working despite not being exposed water, it could be due to a glitch in the receiver module or internal electronic chip. In these cases you can reprogramme the key fob with an OBDII scanner may help.

Water Damage

If your key fob has gotten submerged in a puddle or pool or gone through the washing machine, you could be suffering some water damage. It's generally possible to repair it by taking out the batteries and cleaning the circuit board with rubbing alcohol. It's a good idea let the fob dry completely before putting in 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 updating. You can find the instructions for the reprogramming of most remote keys on YouTube or in your owner's manual. You can also try resetting the car's onboard computer by using the OBDII scan tool.

Faulty Receiver Module

The key fob is equipped with the chip that communicates the vehicle's system. This chip will stop sending and receiving signals to the car if damaged. Dropping the key fob could cause this, as can water exposure. If your key fob stopped functioning due to exposure to water and you are unable fix the issue if you clean the chip using electronic cleaner or isopropylethanol.

However, if the key fob is still unable to not respond even after cleaning it then it is likely that the receiver module is not functioning properly and will need to be replaced. A faulty receiver module can also cause the remote control key to stop functioning. This is usually caused by electromagnetic interference.

Faulty Electronic Chip

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

A faulty chip may also be caused by interference from other objects, bad weather or transmitters located near your vehicle. In this scenario it is likely that a new fob would be needed.

Faulty Battery Contacts

The battery contacts inside the key fob are fragile and are susceptible to damage through repeated use. If they're damaged or bent, the key fob will not send any signals to the receiver modules inside the car.

Modern fobs are designed with rubber seals that keep out water. A splash of water or a light rain is fine however, submerging them in saltwater may cause damage to the chip's electronic components.

The key fob contains a chip which communicates with the immobilizer system of the vehicle to start it. This system makes use of cryptocoding systems in modern vehicles and the older red fiat 500 key fob system used in older models. If the chip is not working properly it must be replaced.

Faulty 12 Volt Battery

A damaged battery could cause the key fob to function. If this happens the car's computer will not recognize that the remote is in the vehicle.

Test the battery using the help of a voltmeter to determine its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly it's time to change it.

Set an electrical load for a short period of time on the battery to test its capacity. This will eliminate one percent of the surface charges. After that, measure the voltage. The greater the battery's capacity and the longer it can maintain its voltage. Ideal is to hold close to 12 volts over several minutes.

The radio signal is not working properly. Radio Signal

This is the most frequent reason for a key fob to stop sending signals to a car. This problem can be solved by replacing the battery. It is important to buy a battery with the same voltage and dimensions as the original.

The buttons are not impervious to destruction and can take a lot. The battery buttons and the contacts are fragile and can be bent or damaged by the force of.

A signal may also be impacted by other objects or transmitters that use the same frequency. A light-control panel at your home, for example can interfere with key fobs that use the same frequency. This could interfere with the remote control of your car.

The tool is not working properly. OBDII scan tool

There are many reasons scanners don't work. Some are more complex than others.

Professional scan tools let mechanics to monitor the car's network and run various self-tests. They can be huge time-savers, but they can also be very expensive, and out of the budget of most DIYers.

If your OBD2 scan tool fails to turn on, check voltage at the terminals 16 (scantool power) and 4 (chassis earth). If all is fine, a fuse may have failed. This is one of the most frequent reasons for failure of the scanner. The simple fix is usually to replace the blown fuse.
