The old battery is then pushed through the hole at the middle. Be careful: If you change the battery improperly or with a battery not suitable, it may damage the remote. Always replace the battery using one with the same size, voltage and specifications as the original.
Alternatively, if your key fob has been submerged in water, you may need to clean the chip before replacing the battery. This is particularly important when you drop it in the ocean or in soapy washing water. This must be addressed 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 coin battery is dead. This is easy to fix and only takes a few minutes. The key fob will also stop working if its buttons are worn. It is simple to fix the issue that requires you to replace the old key shell with the new one.

If the key fob doesn't work after replacing it or reprogramming it or replacing the receiver module, it could be faulty.
Water Damage
The rubber seals on the key fob block water from getting into the electronic chip. However it's not enough to prevent the occasional splash or bath. If your pet has survived a wash cycle, or an ocean swim, it could have damaged the chip.

This is the component in the car that receives signals from the key fob and transmits signals to the key ignition system. If you have an extra key fob, you can test it. This should make the ignition system light come on and the central locking activate. If this doesn't happen, the receiver module is defective. This is a costly fix but it is possible to fix by a professional at your local garage.
