Dead Coin Battery
If your key fob is not working and you are unable to reprogram it, the most likely cause is an inoperative battery. By replacing it, you can make it functional and running again. You can do it yourself in less than 10 minutes.
Flip the key open first from the side, without the rings made of metal. You can open the clip-on lid using your nail. The old battery is then pushed through the hole at the middle. Note: Changing the battery incorrectly or with an unsuitable battery can damage the remote key. Replace the battery with the same voltage, size and specification as the original.
In addition, if your key fob was submerged in water, you could have to clean the chip prior to replacing the battery. This is especially crucial if you've dropped it in the ocean or in soapy washing water. This should be taken care of immediately as exposure to water may damage the electronic chip and cause the key fob to cease working.
Worn Buttons
Seat Ibiza keys stop working the majority of the time often because the battery is dead. This is simple to fix and can be done in a couple of minutes. The key fob also stops functioning if the buttons are worn out. This is another easy fix that requires you to swap the old key shell for a new one.

It's important to note that the button cell battery needs to be replaced correctly or damage could be caused to the key fob. It is recommended to always utilize a brand new battery with the same size as well as the voltage, specifications, and size. It's crucial that the polarity is facing upwards on the new battery.
Rubber seals should keep water away from the key fob. In the event that you submerge the keyfob into water, it may cause the seals on the keyfob to break, causing damage to the electronic chip. This typically happens when you accidentally drop your key fob in the pool or leave it in the rain. If the key fob doesn't work after reprogramming or replacing it or reprogramming it, the receiver module could be in trouble.
Water Damage
The key fob has rubber seals that prevent water from getting into the electronic chip inside. However it's not enough to stop the occasional bath or splash. If your pet been through a wash or swimming in the ocean it could have damaged the chip.
It is possible to fix this by removing the battery and cleaning the chip with isopropyl alcohol or electronic cleaner. Allow it to dry completely, then put it back. If the chip is damaged then it must be replace it with a brand new one.
If your key fob does not work after changing the battery and reprogramming, there could be due to a problem with the receiver module. This is the component of the car that receives the signals from the keyfob, and then sends the signals to the key ignition system. You can test it by using the spare key fob in case you have one. It should trigger the ignition system light come on and the central locking activate. If this doesn't happen then the receiver module may be defective. This is a pricey fix, but it can be done by a professional in your local garage.
Radio Interference
If your car's radio seems to be acting strangely or the key fob no longer functioning it could be caused by an interference issue with the receiver module within the key. This can be fixed with replacing the key with the new receiver module made by Seat parts.
To replace the battery, pull off the key piece and then using your thumb nail or screwdriver that has a flat head, gently pry upwards the key fob's compartment cover. Take off the old CR2025 battery and insert a fresh one, making sure it is in the correct the polarity. You can also use a standard key that has the transponder chip which was transferred from the damaged or worn key. This can be cut and coded to your car if needed.
Faulty Receiver Module
The receiver module in the fob that you have in your keys transmits radio signals to your car. If the fob isn't working it could be because the module has become defective. This can be detected using an OBDII scan tool or by contact with the dealer.
Other devices that operate on the same frequency may interfere with the remote keyless entry system. This can include wireless phone transmitters, electronic devices, and even some household appliances.
If The KeyLab is in contact with pure tap water, it might be possible for you to clean the chip using paper towels and isopropyl Alcohol. If the key fob was submerged in salty or soapy water or left for a long period of time on a wet surface it is almost certain to be damaged and need to be replaced.
To change the battery, use small screwdrivers with flat heads or a fingernail to push open the compartment for button cell batteries (B). Remove the old battery. Insert a new CR2025, making sure that the "+" polarity is facing up.
