Take off the cover of the battery compartment on the key fob (A). By using a flat-head screwdriver a thumb nail, push the cover upwards and replace the CR2025.
Dead Coin Battery
If your key fob has stopped functioning and you're not capable of reprogramming it with a new code, then the most likely reason is a dead coin battery. You can replace the battery yourself in less than ten minutes.
Flip the key open first from the side with no metal rings. It is possible to open the clip-on cover using your nail. The old battery will be removed through the hole in the middle. Note: Changing the battery incorrectly or with an unsuitable battery may damage the remote key. Replace the battery using the same size, voltage and specification as the original.
If your key fob was submerged in water you might also need to clean the chip prior to replacing the battery. This is especially crucial if you've dropped it in the ocean or in soapy wash water. It's crucial to do this as soon as possible, because water could damage the chip in your key fob's electronic.
Worn Buttons
Seat Ibiza keys stop working most often because the coin battery is dead. It is a simple fix and can be done in a couple of minutes. The key fob can also stop working if the buttons are worn out. It's simple to fix and only requires you to replace the key shell that was used to replace it with a new one.
It is essential to replace the button cell battery correctly otherwise the key fob could become damaged. It is recommended that you always make sure you use a new battery of the same size as well as voltage and specifications. It's important that the polarity is facing up on the new battery.
Rubber seals should keep water out of the key fob. Submerging the keyfob in water may cause the seals on the keyfob to break and damage the electronic chip. This is usually the case when the key fob is placed in the rain or accidentally drops into the pool. If the key fob doesn't work after replacing or reprogramming it or replacing the receiver module, it may be defective.
Water Damage
The rubber seals on the key fob stop water from getting to the electronic chip. However, this doesn't stop the occasional splash. If your fob has been through a wash or an ocean swim, it may have damaged the chip.
This can be resolved by removing the battery, and cleaning the chip using isopropyl or electronic cleaner. Dry it completely and then put it back. If the chip has become damaged then it must be replace it with a new chip.
If your key fob still isn't working after changing the battery and reprogramming it, then it could be due to a issue with the receiver module. This is the part of the car that receives signals from the key fob and relays them to the key ignition system. If you have a spare key fob you can test it. This should cause the ignition system light come on and the central locking button activate. If this does not happen, the receiver module is faulty. This is a cost-effective fix, however, it can be fixed by a professional at your local garage.
Radio Interference
The receiver module inside your key could be causing interference. Seat parts can provide an alternative key that comes with a new receiver.
To replace the battery, simply flip off the key piece and then using your thumb nail or screwdriver with a flat-headed head, gently push upwards the key fob's compartment cover. Remove the old CR2025 and replace it with a new battery, ensuring that the polarity is in the right place. You can also use a standard key with the transponder chip which was transferred from the damaged or worn key. The chip can be coded and cut to fit your car in the event that it is needed.
Faulty Receiver Module
The receiver module is the part in the key fob that transmits the radio signals to your vehicle. The module could be faulty when the fob ceases to function. This can be identified with an OBDII scan tool or by getting in touch with the dealer.
Other devices that use the same frequency may interfere with the remote keyless entry system. This can include mobile phones, electrical devices, and even household appliances.
If the key fob has been exposed to pure tap water, it might be possible for you to clean the chip with paper towels and isopropyl Alcohol. If the key fob is submerged in salt or soapy water, or is sat on a floor that is wet for prolonged periods, this will almost certainly result in damage and is likely to need replacing.
To change the battery on your key fob make use of a thumb nail or small screwdriver that has a flat head to break open the cover of the button cell battery compartment (B). Remove the battery that was in place. Insert a new CR2025 and ensure that the "+" orientation is facing up.
