Replace the CR2025 battery, making sure it is installed in the correct direction.
Dead Coin Battery
The most frequent reason for a seat leon replacement key fob to not be able to lock or unlock your car is a dead battery. It usually shows signs before it dies like a lower range or no power at all. It is easy to replace with a brand new one (CR2025) from a local supermarket. Be aware that defective or unsuitable batteries can damage the key fob. Make sure that the battery you purchase is identical in size, specifications and voltage as your old one.
If your device was exposed to clean water such as rain or soapy tap water it is possible that the chip inside has been damaged by corrosion. You can clean the chip using isopropyl or electronic cleaners to see if it helps, but it's likely that the chip is fried.
The most straightforward solution is to get an entirely new key fob. Most major car dealers offer them and they can be installed by a seasoned mechanic. They can also be bought on ebay. It is recommended to work on a surface with good lighting. This will make it easier to work on small parts inside. This also helps you to avoid putting anything back in the wrong place. Always work on your key fob in a location that is safe and secure.
Water Damage
If your key fob gets wet from dropping it into the pool or by slipping it in the washing machine, you may think that it's gone but there's hope. The issue begins when the circuit board inside the fob comes in contact with water - it makes an excellent conductor and shorts out components. It also accelerates corrosion and rust.
This is a simple solution. Find something absorbent to put inside the fob. A tissue or paper towel would work. Then apply a cotton swab dipped in isopropyl alcohol and wipe down the circuit board and other components to clean out any residue of battery acid and contamination. Let the circuit board dry for a few days in a dry, warm environment.
Replace the battery once the fob has dried by replacing it with a new one that has the same dimensions and polarity ('+' (pointing upwards). The fob may be difficult to open in order to access the battery, however when you have a flat head screwdriver in your toolbox, it should be easy to insert. After the fob is reassembled it should function like normal. If it doesn't, then you'll require reprogramming it or replace the receiver module.
Radio Interference
If a keyfob works properly, it sends out a radio frequency that is received by a receiver module in your vehicle. If the signal is damaged in any way the key fob won't function as expected. This may be due to things, weather conditions or other transmitters operating on the same frequency band close to your car.
This can cause your key fob to not activate the vehicle's functions for example, the ignition switch or security system. It is best to replace your key fob's battery.
A few aftermarket LED lighting fixtures that utilizes the same frequency as a remote key fob might interfere with the signal, preventing it from reaching the receiver modules. The LED lighting must be switched off or changed to a different frequency to avoid interference.
If you've got a new battery in your key fob and the issue persists, it is likely that the key fob's antenna is damaged or has stopped working. This is significant 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 exactly what's wrong with the system. The scanner will ask for details about your vehicle including the make and model, engine type, and VIN number.
Faulty Receiver Module
The key fob is equipped with a receiver module which transmits signals for locking and unlocking. If the receiver module fails that causes it to fail, the entire onboard electronics will cease to function. Reprogramming the key fob by an OBDII scan or replacing it can help.
This problem could be caused by a dead coin-cell or water damage, or signal interference. You can reset the on-board computer if you disconnect the 12 Volt batteries for 15 minutes. This will remove any remaining electric current that could cause issues. Take the cable off first of the negative terminal, then the positive terminal. After 15 minutes, you can reconnect your battery in reverse order. First positive, then negative next.
Water or dirt can also affect the internal chip inside the key fob. If your key fob stopped functioning after getting wet, clean it with isopropyl or electronics cleaner. Then, you can reinstall the battery. If it has stopped working after exposure to salty or soapy water, the chip is probably damaged and needs to be replaced.
A defective fuse for the antenna module could also be the cause. This is the fuse that sends a signal to the vehicle to lock or unlock. Depending on your model the fuse can be found in a variety of places such as the engine bay, to the left of the dashboard, beneath the rear seat replacement car key, or in the trunk.
