If the key fob isn't working even though it is not exposed to water, it could be due to a malfunction in the receiver module, or even in the internal electronic chip. Reprogramming the keyfob with an OBDII scan may aid in these situations.

Faulty Receiver Module

The key fob's chip is the chip that communicates 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 due to exposure to water. If your key fob stopped working due to exposure to water, you may be able to fix it if you clean the chip with electronic cleaner or isopropylethanol.

If the key fob won't respond to cleaning, it is possible that the receiver module has a fault and needs to be replaced. A damaged receiver module may also cause the remote control key to cease functioning. This is usually due to electromagnetic interference.

Faulty Electronic Chip

Modern fobs feature rubber seals that keep out water. Submerging them in water even if just the slightest splash or drizzle can harm the electronic chip.

The key fob has an embedded chip that communicates to the immobilizer system of the vehicle, allowing it to start it. The system relies on cryptocoding systems in modern vehicles and the older red key system for older ones. This chip will need to be replaced if faulty.

A faulty 12 Volt battery

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

Test the battery with the voltmeter before replacing it to determine its capacity. A fully charged battery should display 12.6 volts. If the reading drops significantly, it's time to replace it.

Set an electrical load for a short period of time on the battery to gauge its capacity. This will take away approximately 1% of the surface charge. Then, measure the voltage once more. The greater the battery's capacity and the longer it can maintain its voltage. Ideal is that it stays close to 12 volts over several minutes.

Faulty Radio Signal

This is the most frequent reason for keys not sending signals to cars. The battery can be replaced to fix this problem. It how much is a new fiat 500 key essential to purchase a battery that has the same voltage and dimensions as the original.

Fobs aren't impervious to damage and can be damaged by a lot. Contacts and buttons on batteries can be damaged by rough handling.
