Water Damage

If your key fob is damaged by dropping it in the pool or by slipping it in the washing machine, you may think that it's lost but there's a chance. If the circuit board inside the fob is exposed to water, it transforms into an electrical conductor, which shorts the components. It also accelerates the process of corrosion and rust.

Fortunately, this is not difficult to fix. Simply find something absorbent and place it inside the fob. Paper towl or tissue is ideal. Make use of a cotton swab and isopropyl to cleanse the circuit board, and any other components. Allow the circuit board to air dry in a dry, warm environment for a few weeks.

The fob might be difficult to open to get to the battery, however when you have a flat head screwdriver it will be simple to slide in. After the fob has been reassembled, it should work as normal. If it fails then you might need to program it again or replace the module.

Radio Interference

When a keyfob operates properly, it broadcasts a radio signal that is received by a module inside your vehicle. If the signal is disrupted in any way the key fob won't function properly. This could be due to objects or weather conditions, or other transmitters operating at the same frequency as your car.

If you have a new battery on your key fob but the issue persists, it's possible that the antenna on the key fob is damaged or malfunctioning. This is important because the antenna is responsible for transmitting signals from the key fob to the receiver module. An OBDII scanner can aid in diagnosing the issue by telling you what is wrong with the system. The scanner will ask for information about your vehicle including the make, model engine type, and VIN number.

Faulty Receiver Module

The key fob comes with a receiver module that sends signals to lock and unlock the key fob. If the receiver module develops a fault, all of the on-board electronics will cease to function. Reprogramming the key fob using an OBDII scan, or replacing it may help.

There are several possible causes for this issue which could be due to a dead coin battery, water damage, or signal interference. You can reset the onboard computer by disconnecting the 12 volt batteries for about 15 minutes. This will draw out any remaining power that could be causing issues. The cable should be removed first from the negative terminal, then the positive terminal. After 15 minutes, connect your battery in reverse order. First, positive and then negative second.

The presence of dirt or water could harm the internal chip of the key fob. If your key fob stops working after getting wet, clean it with isopropyl or electronic cleaner. After that, replace the battery. If it has stopped working after exposure to salty or soapy water the chip may be damaged and needs to be replaced.

Another possibility is a defective antenna module fuse that is sending the lock and unlock signal to the vehicle. Depending on your model, the fuse is located in one of the many locations such as the engine bay, side of the dashboard, beneath the rear seat spare key leon key programming (navigate to this web-site), or in the trunk.
