Receiver Module Issue

If your key fob stops working, it might be due to the receiver module having developed a fault. Water damage is among the numerous causes. It can happen when you drop your keys, or wash them. It is possible to solve the problem by removing your chip and cleaning it with isopropyl or an electronic cleaner. This will help to keep the chip from getting damaged.

This will eliminate any remaining electrical energy, allowing the system to reboot.

Before replacing the battery it is essential to ensure it's of the correct type and size. If the replacement battery isn't big enough or has an unsuitable voltage, it can damage the circuit board inside the fob's key. You should also remove any corrosive substances from the chip inside the fob prior to installing a new battery.
