Remove the cover for the battery compartment on the key fob (A). By using a thumb nail or flat-head screwdriver. Pull upwards the cover and replace the CR2025 battery.

Dead Coin Battery

If your key fob isn't working and you haven't been capable of reprogramming it with an entirely new code, the most likely culprit is a dead coin battery. You can replace this battery yourself in a mere ten minutes.


The key is opened from the side, without the metal rings. You can open the clip-on lid with your nail. The battery that was used is moved through the hole in the middle. Be careful: If you change the battery improperly or with a battery that is not suitable, it could damage the remote. Always replace the battery using one with the same size, voltage and specification as the original.

If your key fob was submerged in water you might also have to clean the chip prior to replacing the battery. This is especially true if it was dropped into the sea or in soapy water. This must be addressed immediately since exposure to water may damage the chip's electronic circuit and cause your key fob to cease working.

Worn Buttons

Seat Ibiza keys stop working most often due to the battery that powers the coin is dead. It's a straightforward fix that takes only a few moments. The key fob will also stop working if the buttons are worn out. This is another easy fix, and requires you to swap out the old key shell for an entirely new one.

It's important to know that the battery for the button is required to be replaced in a timely manner or damage could be caused to the key fob. It is recommended to always use a brand new battery with the same size as well as the voltage, specifications, and size. It's also crucial that the side of the new battery is facing upwards.

Rubber seals are designed to keep water away from the key fob. However, submerging the key fob in water could cause the seals to break and cause damage to the electronic chip inside. This happens most often when you accidentally drop your key fob into the pool or leave it in the rain. If your key fob still doesn't work even after replacing it or reprogramming, the receiver module might be defective.

Water Damage

Rubber seals on the key fob keep water from reaching the electronic chip. However, this doesn't stop the occasional splash. If you've gotten through a washing cycle or swimming in the ocean your chip might be damaged.

This can be fixed by removing the battery and cleaning the chip with isopropyl alcohol or electronic cleaner. Let it dry completely, then put it back. If the chip has become damaged then it must be replace with a brand new one.

If your key fob doesn't work after replacing the battery and reprogramming it there could be a problem with the receiver module. This is the part of your car that receives the signals from the keyfob and sends the signals to the key ignition system. It is possible to test it by using a spare key fob if you have one. It should trigger the ignition system light come on and the central locking switch activate. If this doesn't happen and the receiver is not working, then it could be defective. This is a costly fix but it can be fixed by a professional at your local garage.

Remove the old CR2025 and replace it with a new battery, ensuring that the polarity of the battery is correct. You can also make use of an ordinary key that has a transponder chip that was previously on a damaged or damaged key. It can be coded and cut to fit your car, if needed.

Faulty Receiver Module

The receiver module is the component on the key fob, which transmits radio signals to the car. The module could be faulty when the fob stops functioning. This can be detected using an OBDII scan device or by calling the dealer.

The remote keyless entry system is susceptible to interference from other devices operating on the same frequency. This includes wireless phone transmitters, electronic devices and even some household appliances.

If the key fob has been exposed to clean tap water it may be possible for you to clean the chip with paper towels and isopropyl alcohol. If the fob's key is submerged in salt or soapy water, or sits on a floor that is wet for long periods of time, this will almost certainly result in damage and is likely to need replacing.
