The most commonly cited reason for key fob failure is the battery of the coin is dead. Other causes are water damage, malfunctioning receiver modules, and signal interference.
Dead Coin Battery
If your key fob battery has gone out of service, the first step is to replace it. Make use of a new button battery that is the same voltage, size and specifications as the original.
If the key fob has been exposed to water, like 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 that has been soaked in isopropyl or electronic cleaner.
If the key fob is not working despite being not exposed to water, it could be due to a malfunction in the receiver module or internal electronic chip. In these cases you can reprogramme the key fob with an OBDII scanner could aid.
Water Damage
If your key fob has taken submerged in a pool or puddle or even a trip down the wash machine, you may have some water damage. You can usually 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 to allow the fob to dry completely before putting in a new battery.
It could be that you have a defective module in the event that your key fob stops working after replacing the battery or changing the programming. There are reprogramming guidelines for all vehicles' remote key fobs on YouTube or in your owner's guide. You can also reset the computer of your vehicle using the OBDII scanner tool.
Faulty Receiver Module
The key fob is equipped with an electronic chip that communicates with the vehicle's system. The chip will stop sending and receiving signals to the car if damaged. This can be caused by dropping the key fob or by water exposure. If the key fob you have purchased has stopped working due to exposure to water or water exposure, you might be able to fix it by attempting to clean the chip using electronic cleaner or isopropylethanol.
However, if the key fob is still unable to not respond after cleaning it then it is likely that the component is damaged and will need to be replaced. A damaged receiver module may also cause the fiat ducato remote key programming control key to cease functioning. This is usually due to electromagnetic interference.
Faulty Electronic Chip
The electronic chip that is in your key fob plays a crucial role in the anti-theft security system of your vehicle. It transmits a signal to the immobiliser unit inside your car to inform it whether the key is valid. If the chip is damaged or broken, your vehicle will not start.
A faulty chip can also be caused by interference signals from other objects or weather conditions that are bad, or transmitters on the same frequency as your car. In this situation an upgrade to the fob will be required.
Contacts to the battery are not working properly.
The battery contacts inside the key fob are delicate and may be damaged with hard usage. If they are damaged or bent, the fiat grande punto key fob won't send any signals to the receiver modules inside the car.
Modern fobs are made with rubber seals to keep out water. A splash of water or a light rain should be fine but submerging them into saltwater could damage the electronic chip.
The key fob has an electronic chip that communicates with the vehicle's immobilizer system in order to activate it. This system makes use of cryptocoding systems in newer vehicles or the red key system used in older ones. This chip needs to be replaced if faulty.
A faulty 12 Volt battery
A defective battery can cause the key fob not to function. The car's computer will not recognize the remote when this happens.
Test the battery with a voltmeter before replacing it to determine its capacity. A fully charged battery will read 12.6 volts. If the reading drops significantly, it is time to replace the battery.
Set an electrical load for a few seconds on the battery to gauge its capacity. This will eliminate one percent of the surface charges. Then, test the voltage again. The better the battery's capacity and the longer it can maintain its voltage. The ideal scenario is to keep it close to 12 volts several minutes.
The radio signal is not working properly. Radio Signal
This is the most typical reason behind a key fob that ceases to send signals to the car. This issue can be resolved by replacing the battery. It is however important to purchase a battery with the same size and voltage as the original.
Fobs endure a lot of abuse, but they're also not impervious to destruction. The battery contacts and buttons are delicate and are susceptible to being bent or broken with the force of.
A signal may also be disrupted by other transmitters or objects that operate on the same frequency. For instance, a lighting control panel near your home may send interference over the same bandwidth that key fobs utilize. This can affect the remote control of your car.
Afflicted OBDII Scan Tool
There are a variety of reasons why a scanner tool may not work. Some are more complex than others.
Professional scan tools permit mechanics to examine the car's systems and run a variety of self-tests. These tools can save you a lot of time, but are costly and out of reach for most DIYers.
If your OBD2 scanner isn't turning on Check the voltage on terminal 16 (scan tool power) and terminal 4 (chassis ground). If all is fine it could be that a fuse has ruptured. This is the most common reason for failures of the scanner. The easiest fix is to replace the fuse which has blown.
