Dead Coin Battery

A dead coin battery is the most frequent cause of a key fob that isn't locking or unlocking your car. When it is dead you will notice a decrease in range or no power. It is easy to replace it with a brand new (CR2025) one from your local store. It is important to be aware that using the wrong or non-compatible batteries could cause damage to your key fob. Make sure that the new battery is identical in size, specifications and voltage as the older one.

If your device has been exposed to pure water, such as rainwater or soapy tap water it is possible that corrosion has damaged the chip's electronic circuit. You can clean the chip using isopropyl or electronic cleaners to see if that helps, but it's likely that the chip has been damaged.

The most straightforward solution is to buy a new key fob. They are readily available from major dealerships and can be installed by a qualified mechanic. You can also buy them online, like on eBay. It is best to work on a surface that is equipped with good lighting. It makes it easier to work with small pieces. This can also help to avoid placing anything back in the wrong spot.

Water Damage

If your key fob is submerged after dropping it into the pool or slipping it in the wash you might think that it's lost but there's a chance. The issue begins when the circuit board in the fob comes into contact with water - it makes an excellent conductor and shorts out components. It also speeds up corrosion and rust.

This is an easy solution. Find something absorbent and place it inside the fob. A paper towl or tissue is ideal. Then you can use a cotton swab that has been soaked in isopropyl alcohol to clean the circuit board as well as other components to eliminate any battery acid residue and contamination. Let the fob air dry in a warm, dry environment for several weeks.

After the fob has dried out it is time to replace the battery a new one (of the same size and the same polarity ('+' with the upwards direction). It can be tricky to open the fob to reach the battery, however if you have a small screwdriver that is flat that you have at hand, it will be able to insert easily. After the fob is reassembled it should function like normal. If it doesn't, you may need to reprogramme it or replace the receiver module.

Radio Interference

When a seat leon key fob working correctly, it sends an audio frequency signal that is picked up by the receiver module in your seat car key cover. If the signal is damaged in any way your key fob will not function as expected. This can be caused by objects, weather conditions, or other transmitters that operate on the same frequency in close proximity to your vehicle.

This can cause your key fob not to be able to trigger the vehicle's functions for example, the ignition switch or the security system. In this case it is best to replace the battery inside your key fob.

A few LED lights that are aftermarket and utilizes the same frequency as a remote key fob can interfere with the signal, preventing it from reaching the receiver modules. To avoid interference, the lighting must be switched off or switched to the opposite frequency.

If the issue continues to persist after installing a new battery, the antenna of your key fob may be damaged or not functioning properly. This is important since the antenna is responsible for sending signals from the key fob to the receiver module. An OBDII scan can help diagnose the problem by revealing what's wrong with the system. The scanner will ask you to provide information about your vehicle, including the model, make and engine type as well as the VIN number.

Faulty Receiver Module

The key fob features an electronic receiver that transmits signals for locking and unlocking. If this module develops a fault that causes it to fail, the entire onboard electronics will stop working. Reprogramming the key fob using an OBDII scan or replacing it might help.

There are a number of possible causes that could be the cause, such as a dead coin battery water damage, or signal interference. Try resetting the computer on board by disconnecting the 12 volt battery for 15 minutes. This will flush out any residual electricity that could be causing problems. The cable should be removed first from the negative terminal, then the positive terminal. After 15 minutes, reconnect the battery in reverse order first, positive second.

The presence of dirt or water could affect the internal chip inside the key fob. If the key fob you purchased stopped 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 is likely fried and will need to be replaced.

A defective antenna module fuse could also be the cause. It is the fuse that transmits an indication to the vehicle to lock or unlock. The fuse can be found in various places, based on the type of vehicle. For instance it could be under the rear seat key fob, or in the trunk, or on the side of the dashboard.(Image: https://www.thekeylab.co.uk/wp-content/uploads/sb-instagram-feed-images/308785165_499195788347328_5859105632268553197_nlow.jpg)
