Fiat Panda Key Fob replacement fiat 500x keys nottingham

Fiat Panda key fobs contain a transponder chip which sends signals to your car to open the doors and start the engine. The fob can stop functioning due to a variety reasons.

The most common reason for key fob failure is an inoperable coin battery. Other causes are water damage, a faulty receiver module and signal interference.

Dead Coin Battery

Replace the battery if the key fob has failed. Choose a button battery that has the same voltage, size and specifications as the previous one.

If the key fob was exposed to water, such as a splash of rain or salt water on the beach, it needs to be cleaned before it can be used again. The best solution is to use an old towel soaked in isopropyl or an electronic cleaner.

If the key fob has not been exposed to water, but still does not work it could be due to an issue with the receiver module or an internal electronic chip. In these cases it is possible that reprogramming the key fob with an OBDII scanner can assist.

Water Damage

You could have water damage if your key fob was submerged in a puddle, pool or washing machine. It's possible to get it working by taking the batteries off and cleaning the circuit board with rubbing alcohol. It is best to let the board completely dry before putting in a battery.

If your key fob isn't working even after replacing the battery and reprogramming it, you may have a faulty receiver module. There are reprogramming guidelines for the majority of vehicles' remote key fobs on YouTube or in your owner's guide. You can also reset your computer of your vehicle using the OBDII scanner tool.

Faulty Receiver Module

The key fob contains a chip that communicates with the vehicle's system. If the chip is damaged, it can no longer transmit or receive signals to the vehicle. This can be caused by dropping the key fob or through exposure to water. If the key fob you have purchased has stopped functioning due to exposure to water or water exposure, you might be able to fix it if clean the chip with electronic cleaner or isopropyl ethanol.

If the key fob does not respond after cleaning it, then it is likely that the module is faulty and needs to be replaced. A malfunctioning receiver module could also cause the remote control key to cease functioning. This is usually caused by electromagnetic interference.

Faulty Electronic Chip

The chip inside your key fob is a vital role in the anti-theft security system of your car. It sends a signal to the immobiliser in your car to tell it whether the key is legitimate. Your car won't start if the chip is damaged.

A damaged chip could be caused by interference signals from other objects like bad weather conditions or transmitters on the same frequency close to your car. In this situation it is likely that a new fob would be needed.

Contacts for the battery that are damaged

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

Modern fobs are equipped with rubber seals that keep out water. A splash of water or a light rain is fine but submerging them into saltwater may harm the electronic chip.

The key fob comes with a chip which communicates with the immobilizer system of the vehicle to begin it. It uses the old red keys for older vehicles as well as the cryptocoding system used in modern vehicles. This chip needs to be changed if it is defective.

Problems with 12 Volt Batteries

A damaged battery could cause the key fob not to work. The car's computer won't recognize the remote when this occurs.

Test the battery with an voltmeter prior to replacing it to determine its capacity. A fully charged battery should display 12.6 volts. If the reading falls significantly, it is time to replace the battery.

To determine the capacity of a battery test the battery's capacity by placing an electrical load on it for a few minutes. This will take away one percent of the surface charges. After that, take the voltage once more. The greater the battery's capacity is, fiat panda key the longer it will maintain its voltage. Ideal is that it stays at or near 12 volts for several minutes.

Radio Signal Faulty Radio Signal

This is the main cause of a key fob that ceases to send signals to the car. The issue can be fixed by replacing the battery. It is however important to purchase a battery with the same voltage and size as the original one.

Fobs aren't impervious to damage and Fiat Panda Key can withstand a lot. The battery buttons and contacts are delicate which means they could be bent or damaged from rough use.

A signal may also be disrupted by other transmitters or objects which use the same frequency. A light control panel in your home, for instance, may interfere with key fobs that have the same frequency. This can affect the remote control of your car.

Problems with OBDII Scan Tool

There are a number of reasons why a scan tool may not work. Certain are more complicated than others.

Professional scan tools allow a mechanic to monitor the car's network and run a variety of self-tests. These are great time savers, but they can also be very expensive, and beyond the reach of most DIYers.

If your OBD2 scan tool fails to turn on, test the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If these are both present, it's likely that a fuse has been blown. This is the most frequent reason for a scan tool to fail. It is generally simple to fix the issue by replacing the fuse that has blown.
