However, the key fob may be inoperable due to various reasons.

The most common cause of key fob failure is an inoperable coin battery. Other causes include water damages or a malfunctioning module and interference signals.

Dead Coin Battery

If the battery in your key fob has failed, the initial step is to replace it. Choose a new button battery with the same voltage, size and specifications as the previous one.

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

If the key fob has not been exposed to water but remains inoperable it could be due to a problem with the receiver module or an internal electronic chip. Reprogramming the keyfob with an OBDII scan can help in these instances.

Water Damage

If your key fob took a bath in the pool or puddle or gone through the washing machine, you might have some water damage. It is usually possible to get it working by removing the batteries and cleaning the circuit board using rubbing alcohol. It's a good idea allow the fob to dry completely before installing a new battery.

You could have a damaged module if your key fob stops working after replacing the battery or updating. There are instructions for the reprogramming of most remote keys on YouTube, or consult your owner's manual. You can also reset the computer of your car using the OBDII scanner tool.

Faulty Receiver Module

The key fob has a chip which communicates with the vehicle's system. The chip will stop sending and receiving signals to the car if damaged. Dropping the key fob could result in this, as can exposure to water. If your key fob has stopped working due to water exposure, you may be able fix the issue if you clean the chip using electronic cleaner or isopropyl ethanol.

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

Faulty Electronic Chip

The electronic chip in 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 that tells it if the fiat ducato key fob programming is valid. If the chip is damaged or broken, your vehicle will not start.

A damaged chip could be caused by interference from other objects, weather conditions or transmitters located near your vehicle. 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 can get damaged with hard usage. If they are damaged or bent, the fob won't send any signals to the receiver modules inside the car.

Modern fobs have rubber seals that block out water. In the event of submerging them in water, even if just the slightest splash or drizzle can harm the chip's electronic components.

The key fob contains a chip that communicates with the vehicle's immobilizer system in order to allow it to start. The system is based on the old red keys that were used in older vehicles, or the cryptocoding system used in newer vehicles. This chip will have to be changed if it is faulty.

Poor 12 Volt Battery

A defective battery can cause the key fob to work. When this happens the car's computer will not be able to recognize that the remote is within the vehicle.

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

To test the battery's capacity put an electrical load on it for a couple of minutes. This will remove one percent of the surface charges. Then, you can measure the voltage again. The greater the battery's capacity, the longer it can keep its voltage. Ideally, it will remain at 12 volts or less for several minutes.

The radio signal is not working properly. Radio Signal

This is the most frequent reason for the key fob not sending signals to the car. The battery is able to be replaced to resolve this problem. However, it is important to buy a new battery that has the same voltage and size as the original one.

Fobs aren't indestructible and are susceptible to damage. Contacts and buttons on batteries can be damaged by rough handling.

Other transmitters or objects operating on the same frequency can also disrupt a signal. A light-control panel in your home, for instance, may interfere with fiat 500 replacement key cost uk fobs that use the same frequency. This could interfere with the remote control in your car.

Afflicted OBDII Scan Tool

There are many reasons scanner tools may not function. Some are more complicated than others.

Professional scan tools permit mechanics to monitor the car's network and conduct a variety self-tests. These are great time savers but they can also be very expensive, and beyond the budget of many DIYers.

If your OBD2 scanner doesn't work Check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If both are in good condition it's possible that a fuse is blowing. This is one of the most common causes of a scan tool failing. It is usually easy to fix the problem by replacing the fuse that was blown.
