Water Damage

If your key fob is soaked by dropping it in the pool or slipping it in the washing machine you might think that it's lost but there's a chance. When the circuit board on the fob is exposed to water, it transforms into a conductor that shorts out the components. It also accelerates corrosion and rust.

This is an easy fix. Simply locate something absorbent and place it inside the fob. Paper towl or tissue can be used. Then, use the cotton swab, dipped in isopropyl ethanol to wipe down the circuit board as well as other components to eliminate any battery acid residue and contamination.

If the problem persists after replacing the battery, the antenna of your key fob may be damaged or is malfunctioning. The antenna is responsible to transmit a signal between the key fob and the receiver module. An OBDII scan will help diagnose the problem by revealing what's wrong with the system. The scanner will ask you for details about the vehicle you own, such as the make and model as well as the engine type and VIN number.

Faulty Receiver Module

Take the cable off first of the negative terminal, then from the positive terminal. After 15 minutes, connect your battery in reverse order. First, positive, then negative, and finally negative.

The internal chip in the key fob may be damaged by water or dirt. If the key fob you purchased stopped working after being wet, wash it using isopropyl or an electronic cleaner. Then reinstall the battery. If it is not working after exposure to soapy or salty water, the chip is probably damaged and must be replaced.

A defective antenna module fuse may also be the cause. It is the fuse that transmits an alert to the vehicle to lock or unlock. The fuse may be located in various places, based on the model. For instance, it could be under the rear seat ibiza replacement key, or in the trunk, or the side of the dashboard.
