Dead coin battery
The most common reason for your seatleon key fob not working is a dead battery. This is a straightforward fix that takes only just a few minutes.

The coin battery in the key fob of your Seat Leon is a very vital component of the remote keyless system. It is fitted with clips made of metal which keep it in place and complete the circuit by sending power to the receiver module. If the clips become loose or corroded, they could cause the circuit to fail. To fix the problem replace the battery with one that is the same size, voltage and type.

If the key fob was exposed it is recommended that you clean it using isopropyl alcohol and paper towel. This will prevent further corrosion or damage. Also, you should allow the electronics to dry completely before replacing the battery.
Faulty battery contacts
The key fob of your Leon includes metal retaining clips that hold the battery in place and complete the circuit. If they're not properly tensioned, it can cause problems with contact. This is also common when the battery has been replaced with a battery that's the wrong size or voltage. The best way to fix this is to replace the old battery with a fresh one. Choose a new battery that is exactly the same size and voltage as the original.
The fob could also stop working if the contacts to the battery are defective or there's water damage, signal interference or a 12 volt dead battery. In this case you'll need to shut off the battery that is 12 volts for a couple of minutes. Reconnect the negative and positive cables afterward.

Receiver module that is defective
The key fob of the seat Leon is a small device which transmits signals to the vehicle. If these signals are not properly received, the vehicle's immobilizer mechanism may cease to function. This could be due to interference from objects, poor conditions in the weather, or transmitters that utilize the same frequency band. The key fob may work, but only within the range of a few meters.
Metal clips keep the battery in place inside the key fob. If they get corroded or worn out the contact points could fail. It is easy to replace the battery in your key fob, but be sure it's of the same size and voltage.
If your key fob can not start the car, you may need to replace the receiver module or the battery. This problem can be fixed by a professional at an affordable cost. You can also program the key fob by yourself, saving money on having to pay the dealership to complete the process. A professional can also assist you with other issues, like the malfunctioning TIPM (transmission immobilizer control unit). They can also help you replace the ignition switch or sensor.
Radio interference
The key fob uses radio waves to communicate with the car, but the signals can be mangled if there is a large amount of interference in the vicinity. The Keylab can happen from broadcast towers, airplanes, and even satellites. This type of interference can also alter the range of your remote. If your remote only works from a short range Try placing it close to your head or chin and check if this solves the problem.
Resetting the receiver module can be enough to repair the problem of a Leon keyfob that isn't working. This can be done by disconnecting the battery for a couple of minutes (first then, the negative cable and then the positive cable). The key fob should then work normal. If not, you may be required to visit an authorized dealer for reprogramming. You can also employ an OBDDII scanner to identify the issue. It's possible that the electronic chips inside the key fob have developed an issue and need to be replaced. This is especially true when the key fob is been exposed to salt or water.
