fiat key fobs Panda keyfobs are equipped with a transponder that sends signals from the fob to the car that allows it to unlock doors or start the motor. The fob may stop working due to a variety of reasons.

The most frequent cause of key fob failure is the battery of the coin is dead. Other causes include water damage a faulty receiver module, and signal interference.

Dead Coin Battery

Replace the battery if the key fob has gone out of service. Make use of a new button battery that is the same size, voltage and specifications as the original.

If the key fob was exposed to water, like a splash of rain or salt water on the beach, it will need to be cleaned before it is able to be used again. The best solution is to use a paper towel that has been soaked in isopropyl or electronic cleaner.

If the key fob is not working despite not being exposed water it could be due to a malfunction in the receiver module, or even in the internal electronic chip. In these instances, reprogramming the key fob using an OBDII scanner may help.

Water Damage

There could be water damage how to start fiat 500 without key your key fob if it was submerged in a pool, puddle or washing machine. It is usually possible to be able to get it back up and running by removing the battery and scrubbing the circuit board with isopropyl alcohol. It is a good idea to let the fob dry completely before putting in a brand new battery.

It could be that you have a defective module if your key fob stops working after replacing the battery or reprogramming. You can find reprogramming instructions for the majority of vehicles' remote key fobs on YouTube or in the owner's manual. You can also try resetting the car's computer onboard using the OBDII scan tool.

Faulty Receiver Module

The key fob contains a chip that communicates with the car's system. This chip will stop sending and receiving signals to the car if it becomes damaged. This can be caused by dropping the key fob or by exposure to water. If the key fob stops working after exposure to water, it may be possible to fix it by cleaning the chip with isopropyl alcohol, or electronic cleaner.

If the key fob doesn't respond to cleaning, it is possible that the receiver module has issues and needs to be replaced. A defective receiver can cause the key to cease to function. This usually happens due to electromagnetic interference.

Electronic chip that is malfunctioning

The electronic chip inside your key fob is a vital part in the anti-theft security system of your car. It transmits a signal to the immobiliser unit of your vehicle to tell it whether or not the key is genuine. The car won't start if the chip is damaged.

A damaged chip could be caused by interference from other objects, weather conditions or transmitters near your vehicle. In this situation you'll need a new key fob.

Contacts for the battery that are damaged

The battery contacts on a key fob can be damaged through heavy use. If they're bent or broken the fob will not be able to send any signals to the receiver modules in the car.

Modern fobs are designed with rubber seals that keep out water. A splash of water or a light rain should be fine However, submerging them in salt water could harm the chip's electronic components.

The key fob comes with an embedded chip that communicates to the immobilizer system of the vehicle to start it. The system uses the old red keys for older vehicles, or the cryptocoding system found in newer vehicles. This chip needs to be replaced if it's malfunctioning.

A faulty 12 Volt battery

A damaged battery could cause the key fob to work. When this happens the car's computer cannot recognize that the fiat doblo van remote key is within 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 drops significantly, it's time to replace it.

Set an electrical load for a short period of time on the battery to check its capacity. This will take away one percent of the surface charges. Then take another measurement of the voltage. The longer the battery can hold its voltage and the higher its capacity. Ideal is to hold close to 12 volts during several minutes.

Radio Signal Faulty Radio Signal

This is the most frequent reason for the key fob not sending signals to vehicles. This issue can be fixed by replacing the battery. It is essential to purchase an identical battery dimensions and voltage as the original.

Fobs endure a lot of abuse, and they aren't impervious to destruction. The battery contacts and buttons could be damaged by rough handling.

The signal could also be interrupted by other transmitters or objects that use the same frequency. A light-control system in your home, for example can interfere with key fobs using the same frequency. This can affect the remote control of your car.

Incorrect OBDII Scan Tool

There are many reasons why scanners may not function. Certain are more complicated than others.

Professional scan tools allow a mechanic to look over the car's networks and perform a variety of self-tests. These tools can help save time, but they're expensive and not accessible to the majority of DIYers.

If your OBD2 scan tool doesn't turn on, check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If they are all OK there is a chance that a fuse has failed. This is the main reason for a scan tool to fail. The simple fix is usually to replace the fuse that has been blown.
