Fiat Panda Key Fob Replacement

fiat key cover Panda key fobs contain a transponder chip which sends signals to your car to unlock the doors or start the engine. The fob may stop working due to a variety reasons.

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

Dead Coin Battery

If your key fob battery is dead, the first thing to do is replace it. Choose a new button battery with the same size, voltage and specifications like the previous one.

If the key fob was exposed to water, Fiat Panda Key Fob Replacement like a splash of rain or salt water on the beach, it's going to need to be cleaned before it is able to be used again. A paper towel soaked with isopropyl alcohol or electronic cleaner will help.

If the key fob hasn't been exposed to water but still does not work it could be because of an issue with the receiver module or an internal electronic chip. Reprogramming the keyfob through an OBDII scan may help in these cases.

Water Damage

It is possible to get water damage to your key fob if it was submerged in a pool, puddle or washing machine. It's generally possible to fix it by getting rid of the batteries and cleaning the circuit board with ruby alcohol. It is best to let the fob completely dry before putting in the battery.

If your key fob stopped working, even after replacing the battery and reprogramming it, you may have a problem with the receiver module. You can find information on reprogramming most vehicles' remote keys on YouTube, or consult your owner's manual. You could also try resetting the car's onboard computer by using the OBDII scan tool.

Faulty Receiver Module

The key fob's chip is a chip that communicates with the vehicle's system. If this chip becomes damaged, it will be unable to longer be able to send or receive signals to the vehicle. This could be due to dropping the key fob, or due to exposure to water. If the key fob has stopped working after exposure to water it could be possible to repair the issue by cleaning or cleaning the chip using isopropyl alcohol, or electronic cleaner.

If the key fob is still unable to not respond after cleaning it it is likely that the component is damaged and will require to be replaced. A malfunctioning receiver could cause the key to stop working. This is typically caused by electromagnetic interference.

Faulty Electronic Chip

The chip that is embedded in the key fob is an important element of the anti-theft device in your car. It sends a signal the immobiliser unit in your vehicle to tell it whether or not the key is in fact valid. If the chip is damaged or broken, your car will not start.

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

Faulty Battery Contacts

The battery contacts inside the key fob are fragile and are susceptible to damage through repeated use. If they're bent or broken, the fob won't send any signals to receiver modules in the vehicle.

Modern fobs come with rubber seals to keep out water. A splash of water or a light rain is acceptable but submerging them into salt water could damage the chip's electronic components.

The key fob is equipped with an electronic chip that communicates with the vehicle's immobilizer to allow it to activate it. This system uses crypto coding systems in the latest vehicles and the older red key system in older models. If the chip is not working properly, it will need to be replaced.

The 12 Volt Battery is faulty

A malfunctioning battery could cause the key fob to function. The car's system will not recognize the remote if this happens.

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

Install an electrical charge for a short time on the battery to check its capacity. This will take away 1% of the surface charges. After that, take the voltage again. The longer the battery can hold its voltage and the higher its capacity. Ideal is to hold at or near 12 volts for several minutes.

Radio Signal Faulty Radio Signal

This is the most frequent cause of a key fob that ceases to send signals to the car. The battery could be replaced to fix this issue. However, it is important to buy a new battery that is the same voltage and size as the original.

The buttons are not impervious to destruction and can withstand a lot. The battery buttons and the contacts are fragile and can be bent or broken by excessive use.

Other objects or transmitters using the same frequency can also disrupt a signal. For example, a light-control panel in your home could transmit interference on the same bandwidth that key fobs utilize. This could interfere with the remote control in your car.

Incorrect OBDII Scan Tool

There are many reasons why a scanner tool may not function. Some are more complex than others.

Professional scan tools allow a mechanic to look over the car's networks and Fiat Panda Key Fob Replacement run a range of self-tests. These are great time savers, however they are also extremely expensive and are out of the range of most DIYers.

If your OBD2 scan tool doesn't turn on, make sure you check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition it could be that a fuse has blown. This is the most common reason for failures of the scanner. It is often simple to fix the issue by replacing the fuse that has blown.
