Dead Coin Battery

The most common reason for a key fob to not allow you to lock or unlock your car is a dead coin battery. It will usually show symptoms before it dies like a lower range or no power at any time. It is easy to replace it with a new (CR2025) one from your local store. It is important to be aware that using the wrong or non-compatible batteries can damage your key fob. Make sure that the battery you purchase is identical in size, specifications and voltage as the previous one.

If your fob has been exposed to clean water, such as rainwater or soapy tap water, it is likely that corrosion has caused damage to the electronic chip. You might try cleaning your chip with isopropyl Alcohol or an electronic cleaner to try to see if this helps but it is likely the chip has fried.

A new key fob is the simplest solution. They are available at most major car dealers and can be fitted by a professional mechanic. You can also buy them on the internet, for instance on eBay. The best way to work is to work on a flat, level surface with adequate lighting. This will make it easier to work on the smaller parts inside. This will also help you to avoid putting something back in the wrong spot. Always work on the key fob in a secure and safe place.

Water Damage

If your key fob gets submerged after dropping it into the pool or throwing it in the wash you might think that it's lost but there's still hope. The issue begins when the circuit board inside the fob comes into contact with water - it is a great conductor, and it shorts out the components. It also accelerates corrosion and rust.

Fortunately, this is not difficult to fix. Find something absorbent to put inside the fob. A paper towel or tissue will be ideal. Then make use of an alcohol-soaked cotton swab and a cotton swab isopropyl alcohol to wipe down the circuit board and other components to clean out any residues of acid from batteries and contamination. Let the fob dry out for a few days in a dry and warm environment.

After the fob has dried out, replace the battery with another one of the same size and the same polarity ('+' pointing upwards). It can be difficult to open the fob to get access to the battery, but if have a small flat-head screwdriver that you have at hand, it will be able to insert easily. After the fob has been reassembled and working, it should operate like normal. If it doesn't work you may need to re-program it or replace the module.

Radio Interference

When a keyfob is working properly, it broadcasts an audio frequency that is absorbed by a receiver module inside your vehicle. If the signal is distorted in any way the key fob won't perform as it should. This may be due to things, weather conditions or other transmitters operating in the same frequency range close to your car.

This could cause your key fob to not be able to activate the vehicle's systems like the ignition switch or the security system. In this situation, it would be best to replace the battery on your key fob.

A few LED lighting aftermarkets that utilizes the same frequencies as key fobs for remote control could interfere with the signal, preventing it from reaching receiver modules. The LED lighting must be switched off or changed to a different frequency in order to prevent interference.

If the problem persists after installing a new battery, the antenna of your key fob may be damaged or inoperable. The antenna is responsible to transmit a signal between the key fob and the receiver module. An OBDII scan can aid in diagnosing the issue by revealing exactly what's wrong with your system. The scanner will ask for information about your specific vehicle like the model and make as well as the engine type and VIN number.

Faulty Receiver Module

The key fob is equipped with an electronic receiver that transmits signals to lock and unlock the key fob. If this module fails then all the on-board electronics will stop working. Reprogramming the key fob by an OBDII scan or replacing it might help.

There are several possible reasons for this problem which could be due to a dead coin battery water damage or signal interference. You can try resetting the computer on board by disconnecting the 12 volt battery for 15 minutes. This will drain any remaining electricity that could be causing problems. Start by removing the cable from the negative terminal of the battery first, followed by the positive terminal. After 15 minutes, connect the battery in reverse order beginning with positive first, and negative second.

Dirt or water can damage the internal chip of the key fob. If your key has stopped working after it got wet, you need to clean the electronic component with isopropyl alcohol or an electronics cleaner before reinstalling the battery. If it has stopped working after exposure to salty or soapy water the chip is likely damaged and needs to be replaced.

A defective antenna module fuse could be a cause. It is the fuse that transmits an electronic signal to the vehicle to lock or unlock. The fuse could be found in various places, based on the type of vehicle. For example it could be under the rear Seat Leon Key Programming, or in the trunk, or on the side of the dashboard.
