A dead battery for the coin is the most frequent reason for malfunctioning keys. Other causes include water damages or a damaged module and interference signals.

Dead Coin Battery

If your key fob's battery has died, the first thing to do is replace it. Choose a button battery that has the same voltage, size and specifications as the previous one.

If the key fob was exposed to water, for example a splash of rain or salt water at the beach, it's going to need to be cleaned before it is able to be used again. The best method is to use a paper towel soaked with isopropyl or electronic cleaner.

If the key fob doesn't working despite not being exposed water it could be due to a malfunction in the receiver module or internal electronic chip. In these situations it is possible that reprogramming the key fob with an OBDII scanner might help.

Water Damage

You might have water damage if your key fob was submerged in a puddle, pool or washing machine. It is usually possible to be able to get it back up and running by getting rid of the battery and scrubbing the circuit board with isopropyl alcohol. It's a good idea allow the fob to dry completely before putting in a new battery.

There could be a problem with the module when your key fob ceases working after replacing the battery or changing the programming. Reprogramming instructions are available for the majority of vehicles' remote key fobs on YouTube or in the owner's manual. You can also reset your computer of your vehicle using the OBDII scanner tool.

Faulty Receiver Module

The key fob has an electronic chip that communicates with the vehicle's system. This chip will stop sending and receiving signals to the car if it becomes damaged. This can be caused by dropping the key fob, or by exposure to water. If the key fob stopped working after water exposure it may be possible to fix the issue by cleaning the chip with isopropyl alcohol, or electronic cleaner.

However, if the key fob does not respond even after cleaning it there is a good chance that the component is damaged and will require to be replaced. A defective receiver module could also cause the remote control key to stop functioning. This is typically caused by electromagnetic interference.

A malfunctioning electronic chip

The electronic chip inside your key fob plays an important role in the anti-theft security system in your car. It sends a signal the immobiliser unit inside your vehicle to tell it whether the fiat key is valid. If the chip is damaged or broken, your vehicle will not start.

A faulty chip may also be caused by interference from other objects, weather conditions or transmitters in the vicinity of your vehicle. In this case, you will need an entirely new key fob.

Contacts to the battery are not working properly.

The battery contacts in a key fob are very delicate and could be damaged with hard usage. If they're damaged or bent, the key fob won't send any signals to the receiver modules inside the fiat car keys.

Modern fobs are constructed with rubber seals to keep out water. A splash of water or a light rain is acceptable However, submerging them in salt water could harm the electronic chip.

The key fob contains a chip which communicates with the immobilizer system of the vehicle, allowing it to start it. It uses the red keys of older vehicles as well as the cryptocoding system found in newer vehicles. This chip will have to be replaced if it's damaged.

Faulty 12 Volt Batterie

A damaged battery could cause the key fob not to work. The car's system will not recognize the remote if this occurs.

Test the battery using a voltmeter before replacing it to determine its capacity. A fully charged battery should read 12.6 volts. If the reading decreases significantly it's time to change it.

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 about 1% of the surface charge. After that, measure the voltage. The greater the battery's capacity is, the longer it will keep its voltage. It should be 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 fiat scudo key replacement fob not sending signals to vehicles. The battery can be replaced to solve this issue. It is important to buy a battery that has the same dimensions and voltage as the original.

Fobs take a lot of abuse, and they aren't impervious to destruction. The battery contacts and buttons are delicate and can be bent or damaged by excessive use.

A signal can also be interrupted by other objects or transmitters that use the same frequency. For example, a light-control panel that is near your home could transmit interference using the same frequency that key fobs use. This can interfere with the remote control of your car.

Faulty OBDII Scan Tool

There are a number of reasons why a scanner may not work. Some are more complex than others.

Professional scan tools allow a mechanic to examine the car's systems and run a range of self-tests. These tools can help save time, but they are costly and are out of reach for most DIYers.

If your OBD2 scanner won't turn on make sure you check the voltage at terminal 16 (scan tool power) and terminal 4 (chassis ground). If they're both in good shape, it's likely that a fuse is blowing. This is one of the most common causes of scan tool failure. It is typically simple to fix the issue by replacing the blown fuse.
