The fob may stop working due to a variety reasons.
A dead coin battery is the most frequent cause of malfunctioning keys. Other causes are water damage, an inoperative receiver module, and signal interference.
Dead Coin Battery
If the battery in your key fob is dead, the first step is to replace it. Choose a new button battery with the same size, voltage and specification as the previous one.
If the key fob was exposed to water (such as saltwater or rain at the beach) It must be cleaned before being used again. The best method is to use an old towel soaked in isopropyl or an electronic cleaner.
If the key fob has not been exposed to water, but still does not work, there may be an issue with the receiver module or an internal electronic chip. In these instances, reprogramming the key fob using an OBDII scanner can help.
Water Damage
If your key fob's battery has taken immersed in a pool or puddle or walked down the washing machine, it could have some water damage. You can usually be able to get it back up and running by taking the battery off and cleaning the circuit board with isopropyl alcohol. It's a good idea to let the fob dry completely before putting in a new battery.
You may have a faulty module in the event that your remote stops working after replacing the battery or replacing it with. Reprogramming instructions are available for most remote key fobs on YouTube or in your owner's guide. You could also try resetting the car's computer onboard using the OBDII scan tool.
Faulty Receiver Module
The key fob contains the chip that communicates the vehicle's system. If this chip becomes damaged, it will be unable to longer transmit and receive signals to the vehicle. The key fob being dropped can cause this, as well as exposure to water. If the key fob you have purchased has stopped working due to exposure to water and you are unable to fix it by attempting to clean the chip with electronic cleaner or isopropyl alcohol.
If the key fob won't respond to cleaning, it is possible that the receiver module has an issue and should be replaced. A faulty receiver can also cause the fiat punto key replacement cost to not work. This is typically caused by electromagnetic interference.
A malfunctioning electronic chip
The electronic chip in the key fob is a crucial component of the anti-theft system in your car. It sends a signal to the immobiliser inside your car to determine if 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 objects, bad weather conditions or transmitters operating on the same frequency close to your car. In this case, a fiat 500 new key fob will be required.
Faulty Battery Contacts
The battery contacts of the key fob are fragile and are susceptible to damage with hard usage. If they are broken or bent, the fob will not be able to send any signals to the receiver modules inside the car.
Modern fobs are designed with rubber seals that keep out water. A splash of water or light rain should be fine, but submerging them in saltwater may harm the chip's electronic components.
The key fob has chip that communicates with the immobilizer system of the vehicle in order to start it. The system is based on the red keys of older vehicles or the cryptocoding system that is used in newer vehicles. This chip will need to be replaced if it's damaged.
A faulty 12 Volt battery
A faulty battery may cause the key fob to work. The car's computer won't recognize the remote if this happens.
Before you replace the battery, you should test it with a the voltmeter to determine its capacity. A fully charged battery should display 12.6 volts. If the reading falls dramatically then it's time to replace the battery.
Place an electrical load for a short period of time on the battery to gauge its capacity. This will eliminate 1percent of the charges. After that, measure the voltage. The better the battery's capacity, the longer it can maintain its voltage. Ideal is that it stays close to 12 volts over several minutes.
Problems with Radio Signal
This is the most typical reason for the key fob to stop sending signals to a car. The battery can be replaced to solve this problem. But, it is essential to purchase a battery that is the same voltage and size as the original one.
The buttons are not impervious to destruction and are susceptible to damage. Contacts on batteries and buttons can be damaged through rough handling.
The signal could also be interrupted by other objects or transmitters who use the same frequency. For instance, a light control panel near your home may send interference on the same bandwidth that key fobs use. This could interfere with the remote control of your car.
Problems with OBDII Scan Tool
There are a number of reasons why a scan tool may not work. Some are more complex than others.
Professional scan tools enable mechanics to look over the car's network and perform various self-tests. These tools can help save time, but are costly and out of reach for most DIYers.
If your OBD2 scan tool fails to turn on, check voltage at terminals 16 (scantool power) and 4 (chassis earth). If both are in good condition there is a chance that a fuse has been blown. This is one of the most frequent causes of a scan tool failing. The easiest fix is to replace the fuse which has blown.
