A dead coin battery is the most frequent cause of malfunctioning keys. Other causes include water damage, the receiver module is defective, and signal interference.

Dead Coin Battery

If your key fob's battery is dead, the first step is to replace it. Make use of a new button battery that is the same voltage, size and specifications as the old one.

If the key fob was exposed to water, like a splash of rain or salt water at the beach, it will have to be cleaned before it can be used again. A paper towel that has been soaked in isopropyl alcohol or electronic cleaner can help.

If the fiat ducato replacement key fob has not been exposed to water but isn't working it could be an issue with the receiver module or an internal electronic chip. In these situations it is possible that reprogramming the key fob with an OBDII scanner may help.

Water Damage

You could have water damage to your key fob if it was submerged in a pool, puddle or washing machine. It's possible to get it back in working order by getting rid of the batteries and cleaning the circuit board with rubbing alcohol. It's a good idea let the fob dry completely prior to installing a new battery.

You may have a faulty module when your key fob ceases working after replacing the battery or reprogramming. You can find reprogramming procedures for the majority of vehicles' remote key fobs on YouTube or in your owner's guide. You can also try resetting the car's computer onboard using the OBDII scan tool.

Faulty Receiver Module

The key fob has the chip that communicates with the car's system. The chip will stop sending and receiving signals to the car if damaged. This could be due to dropping the key fob, or by exposure to water. If the key fob stopped functioning after exposure to water, it is possible to fix the issue by cleaning the chip using isopropyl alcohol, or electronic cleaner.

If the key fob won't respond to cleaning, it is likely that the module is in an issue and should be replaced. A damaged receiver can cause the fiat key fobs to not work. This usually happens due to electromagnetic interference.

A malfunctioning electronic chip

The chip inside your key fob plays a vital function in the anti-theft security system of your vehicle. It sends a signal the immobiliser unit of your car to inform it whether the key is valid. Your car won't start when the chip is damaged.

A damaged chip could be caused by interference from objects, bad weather or transmitters located near your vehicle. In this instance, a new fob will be required.

Contacts of the battery may be damaged.

The battery contacts on a key fob are very delicate and may be damaged when used for long periods of time. If they're bent or damaged, the fob will not send any signals to receiver modules inside the vehicle.

Modern fobs are designed with rubber seals to keep out water. In the event of submerging them in water, even if it's just an occasional drizzle or splash can harm the chip's electronic components.

The key fob is equipped with an embedded chip that communicates to the immobilizer system of the vehicle to begin it. This system makes use of cryptocoding systems in the latest vehicles and the older red key system used in older models. This chip will need to be changed if it is faulty.

The 12 Volt Battery is faulty

A defective battery can cause the key fob to function. The car's computer will not recognize the remote when this happens.

Test the battery using the help of a voltmeter to determine its capacity. A fully charged battery will display 12.6 volts. If the reading drops significantly then it's time to replace the battery.

Place an electrical load for a few moments on the battery to check its capacity. This will take away approximately 1% of the charge on the surface. Then, measure the voltage once more. The longer a battery is able to hold its voltage and the higher its capacity. It is ideal to maintain close to 12 volts for several minutes.

The radio signal is not working properly. Radio Signal

This is the main cause of a key fob that stops sending signals to the car. This problem can be solved by replacing the battery. It is crucial to buy an identical battery voltage and dimensions as the original.

Fobs are not indestructible and can be damaged by a lot. The battery buttons and contacts are brittle and are susceptible to being bent or broken by rough usage.

A signal can also be impacted by other transmitters or objects that operate on the same frequency. A light-control panel at your home, for instance could interfere with key fobs using the same bandwidth. This can affect the remote control of your car.

Faulty OBDII scan tool

There are many reasons why a scan tool could not function. Some are more complex than others.

Professional scan tools allow mechanics to look over the car's networks and perform a variety of self-tests. These tools can save you a lot of time, but they are costly and are out of reach for the majority of DIYers.

If your OBD2 scan tool doesn't turn on, check the voltage at terminals 16 (scantool power) and 4 (chassis earth). If they are all OK it could be that a fuse has ruptured. This is the most typical reason for a scan tool to fail. The easiest solution is to replace the fuse which has blown.
