Avoid Making This Fatal Mistake With Your Fiat 500 Keys

fiat doblo key fob replacement Panda Key Fob Replacement

fiat ducato replacement key Panda keyfobs are equipped with a transponder which transmits signals from the fob to the car that allows it to unlock doors or start the motor. The fob might stop working for a variety of reasons.

The most common reason for key fob malfunction is an inoperable coin battery. Other causes include water damages or a damaged module and interference signals.

Dead Coin Battery

Replace the battery if the key fob has failed. Make use of a button cell battery with the same voltage, size, and specification as your old one.

If the key fob was exposed to water, for example 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 soaked with isopropyl, or electronic cleaner.

If the key fob has not been exposed to water, but still does not work it could be a problem with the receiver module or an internal electronic chip. In these situations, reprogramming the key fob with an OBDII scanner may assist.

Water Damage

You might have water damage if your key fob was submerged in a pool, puddle or washing machine. It's usually possible to get it working by removing the batteries and cleaning the circuit board with ruby alcohol. It's a good idea let the fob dry completely before putting in a brand new battery.

You may have a faulty module if your key fob stops working after replacing the battery or changing the programming. You can find instructions for the reprogramming of most remote keys on YouTube, or consult your owner's manual. You could also try resetting the car's onboard computer using the OBDII scan tool.

Faulty Receiver Module

The key fob contains the chip that communicates with the car's system. If this chip becomes damaged, it will no longer be able to send or receive signals to the vehicle. A key fob falling off can result in this, as can water exposure. If the key fob is not functioning after exposure to water, it could be possible to repair it by cleaning the chip with isopropyl alcohol or electronic cleaner.

If the key fob doesn't respond to cleaning, it's likely that the module is in issues and needs to be replaced. A faulty receiver can also cause the key to stop working. This is typically caused by electromagnetic interference.

Faulty Electronic Chip

The electronic chip that is in your key fob plays an important role in the anti-theft system in your car. It sends a signal the immobiliser unit of your car to inform it whether or not the key is in fact valid. If the chip is damaged or damaged, your car won't start.

A defective chip could be caused by interference caused by objects, bad weather or transmitters near your vehicle. In this instance an upgrade to the fob will be needed.

Contacts with the battery may be damaged.

The battery contacts of the fob's key can be damaged through heavy use. If they're bent or broken, the fob won't transmit any signals to receiver modules in the vehicle.

Modern fobs are equipped with rubber seals that keep out water. Submerging them in water even if just small splash or drizzle can harm the chip's electronic components.

The key fob is equipped with a chip which communicates with the immobilizer system of the vehicle to start it. The system utilizes the old red keys in older vehicles or the crypto coding system in modern vehicles. If this chip is faulty it must be replaced.

A faulty 12 Volt battery

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

Test the battery with the help of a voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading decreases significantly it is time to replace the battery.

Set an electrical load for a few moments on the battery to gauge its capacity. This will remove approximately 1 percent of the charge on the surface. After that, take the voltage once more. The higher the capacity of the battery and the longer it can maintain its voltage. The ideal scenario is to keep it close to 12 volts several minutes.

Problems with Radio Signal

This is the most common reason behind a key fob that ceases to send signals to the car. The battery could be replaced to fix this issue. It is crucial to buy an identical battery dimensions and voltage as the original.

Fobs aren't indestructible and are susceptible to damage. The battery buttons and contacts are delicate and can be bent or broken by rough use.

Other transmitters or objects operating on the same frequency may also interfere with a signal. A light control panel in your home, for example, may interfere with key fobs which use the same frequency. This can interfere with the remote control of your car.

Afflicted OBDII scan tool

There are a number of reasons why a scanner could not 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, however they can be expensive and are out of the range 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 both are in good condition, a fuse may have ruptured. This is among the most frequent causes of a scan tool failing. The most straightforward fix is to replace the fuse that has been blown.
