Fiat Panda Key Fob Replacement

fiat doblo key fob replacement Panda key fobs contain transponder chips that send a signal to your car to unlock the doors or start the engine. The fob may stop working for a variety of reasons.

A dead battery for the coin is the most frequent cause of a key fob malfunction. Other causes include water damages or a malfunctioning module and interference signals.

Dead Coin Battery

If your key fob's battery has gone out of service, the first thing to do is replace it. Make use of a new button battery that is the same voltage, size, and specification as the old one.

If the key fob was exposed to water (such as saltwater or rain at the beach) it must be cleaned prior to being used again. A paper towel soaked with isopropyl alcohol or electronic cleaner will be the solution.

If the key fob isn't working despite not being exposed water, it could be due to a problem in the receiver module or an internal electronic chip. In these instances, reprogramming the key fob with an OBDII scanner may assist.

Water Damage

You could have water damage to your key fob if it was submerged in a puddle, pool or washing machine. It's possible to repair it by taking out the batteries and cleaning the circuit board with ruby 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 reprogramming it, you may have a malfunctioning receiver module. You can find instructions for reprograming the majority of remote keys on YouTube or in your owner's manual. You can also reset the car's computer using the OBDII scanner tool.

Faulty Receiver Module

The key fob has the chip that communicates the vehicle's system. If the chip is damaged, it can no longer transmit and receive signals to the vehicle. This could be due to dropping the key fob, or due to exposure to water. If your key fob stopped working due to exposure to water, you may be able to fix it if clean the chip with electronic cleaner or isopropyl alcohol.

If the key fob doesn't respond to cleaning, it is possible that the module has issues and needs to be replaced. A malfunctioning receiver could cause the key to not work. This is usually caused by electromagnetic interference.

Electronic chip that is malfunctioning

The electronic chip in your key fob is a crucial component of the anti-theft systems in your car. It sends a message to the immobiliser inside your car to inform it if the key is valid. Your car won't start if the chip is damaged.

A defective chip can be caused by interference signals from other objects such as weather conditions, objects or transmitters on the same frequency as your car. In this case you'll need an entirely new key fob.

Faulty Battery Contacts

The battery contacts of the fob's key can be damaged by excessive usage. If they're damaged or bent, the fob will not be able to send any signals to the receiver modules inside the car.

Modern fobs are made with rubber seals that keep out water. Submerging them in water, even if it is just an occasional drizzle or splash could harm the chip's electronic components.

The key fob has an electronic chip that communicates with the vehicle's immobilizer system to start it. The system utilizes the old red keys in older vehicles, or the cryptocoding system used in newer vehicles. This chip will have to be replaced if faulty.

Problems with 12 Volt Batteries

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

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

Install an electrical charge for a short time on the battery to test its capacity. This will remove one percent of the surface charges. Then, test the voltage again. The longer a battery is able to keep its voltage steady and the higher its capacity. It is ideal to maintain close to 12 volts during several minutes.

Faulty Radio Signal

This is the most typical cause of a key fob that ceases to send signals to the car. The battery is able to be replaced to resolve this problem. It is important to buy a battery with the same dimensions and voltage as the original.

Fobs endure a lot of abuse, but they're also not indestructible. The battery contacts and buttons could be damaged through rough handling.

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

Afflicted OBDII scan tool

There are a number of reasons why a scanner could not function. Certain are more complicated than others.

Professional scan tools enable mechanics to look over the car's network and run various self-tests. They can be huge time savers but they're also expensive and are out of the budget of many DIYers.

If your OBD2 scan tool fails to turn on, make sure you check the voltage at the terminals 16 (scantool power) and 4 (chassis earth). If these are both present, it's likely that a fuse has failed. This is the main cause of scan tool failure. It is often easy to fix the problem by replacing the fuse that was blown.
