If the key fob was exposed to water (such as saltwater or rain at the beach) it must be cleaned before using again. The trick is to use a paper towel soaked with isopropyl, or electronic cleaner.

If the key fob has not been exposed to water but still does not work it could be because of an issue with the receiver module or an internal electronic chip. Reprogramming the keyfob with an OBDII scan may aid in these situations.

Water Damage

If your key fob has gotten submerged in a pool or puddle, or taken a trip down the wash machine, you may have some water damage. You can usually get it working again by removing the battery and scrubbing the circuit board with isopropyl alcohol. It's a good idea to let the fob dry completely before installing a new battery.

There are reprogramming guidelines for most remote key fobs on YouTube or in the owner's manual. You could also try resetting the car's onboard computer with the OBDII scan tool.

Faulty Receiver Module

The key fob's chip is an electronic chip that communicates with the vehicle's system. The chip will stop sending and receiving signals to the car if it becomes damaged. A key fob falling off can cause this, as well as exposure to water. If your key fob isn't working due to water exposure and you are unable to fix it if you clean the chip with electronic cleaner or isopropyl alcohol.

However, if the key fob is still unable to not respond after cleaning it, there is a good chance that the module is faulty and will need to be replaced. A damaged receiver can cause the key to not work. This is usually due to electromagnetic interference.

Faulty Electronic Chip

The chip that is embedded in your key fob is a crucial part of the anti-theft system in your car. It sends out a signal the immobiliser unit of your car to inform it whether or not the key is genuine. If the chip is damaged or broken, your car 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 instance the replacement fob will be required.

Contacts for the battery that are defective

Modern fobs come with rubber seals to keep out water. A splash of water or a light rain should be fine but submerging them into saltwater could harm the chip's electronic components.

The key fob is equipped with a chip which communicates with the immobilizer system of the vehicle to begin it. The system uses the old red keys that were used in older vehicles, or the cryptocoding system found in newer vehicles. If the chip is not working properly it will have how to program fiat 500 key fob be replaced.

Poor 12 Volt Battery

A damaged battery could cause the key fob not to work. If this happens, the car's computer system will not be able to recognize that the remote is inside the vehicle.

Before you replace the battery, test it by using a an voltmeter to gauge its capacity. A fully charged battery should display 12.6 volts. If the reading decreases significantly then it's time to replace the battery.

Set an electrical load for a short period of time on the battery to check its capacity. This will take away 1percent of the surface charges. After that, measure the voltage. The higher the capacity of the battery and the longer it can maintain its voltage. The ideal scenario is to keep it at or near 12 volts for several minutes.

The radio signal is not working properly. Radio Signal

This is the most typical reason for keys not sending signals to the car. This issue can be fixed by replacing the battery. However, it is important to buy a new battery that has the same size and voltage as the original one.

Fobs can take a lot abuse, but they're not indestructible. Contacts and buttons on batteries can be damaged by rough handling.

A signal may also be interrupted by other transmitters or objects who use the same frequency. For example, a light-control panel near your home may transmit interference using the same frequency as key fobs use. This could affect your car's remote control.

Incorrect OBDII Scan Tool

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

Professional scan tools enable mechanics to monitor the car's network and run a variety of self-tests. These can be real time savers, but they're also expensive, and beyond the budget of many DIYers.
