What to Do If Your Seat Ibiza Key Fob Stopped Working
If your key fob stopped working suddenly or it isn't locking and unlocking the car then there are some things to be able to check. The battery might need to be replaced or the electronic chips could be faulty.
The most popular model by Seat is the Ibiza that competes with the Renault Clio and Peugeot 208 in the supermini market. It's also an excellent value.
Battery
The most frequent reason for a keyfob not working is the battery is dead. The battery used in the fob is a 3V lithium button-cell battery (CR 2032). This battery can be bought at retail stores or online. Replace the old battery with new ones that are identical in size, type and specifications. Using a different type of battery could cause damage to the fob.
Metal clips secure the battery inside the fob, which completes an electrical circuit when activated of the remote. If these clips are loose or dirty, they can cause a short and stop the remote from functioning. Use isopropyl or electronic cleaners to clean them.
To change the battery, you must remove the fob. You can do this by inserting a screwdriver into the gap. Replace the battery with a new one. Make sure you install it in the same direction. The fob will then be shut automatically. It is essential to test the fob to be sure that it functions correctly after replacing the battery.
Water Damage
Water damage could be the cause for the key fob to stop working when you dropped it into the pool or washed it in the washer. The electronic chip inside the key fob is protected by rubber seals however prolonged exposure to water can reduce the effectiveness of these seals over time. Water also makes a good conductor which can cause short circuits within the key fob.
Fortunately, the battery for the key fob is easy to replace. Make use of a small screwdriver with a flat head or thumb nail to pull open the cover on the battery compartment of the key fob. Replace the button-cell battery CR2025, making sure the polarity is facing upwards. Close the keyfob battery compartment to re-programme the remote so that it can work with your car.
If your key fob isn't working after replacing the battery and reprogramming it then it's possible that the receiver module has developed an issue. The receiver module is the component that receives signals from the key fob and sends the signals to your car in order to control the ignition, engine and central locking.
Faulty Chip
If your Seat Ibiza key fob stopped working, there may be an issue with the chip inside it. It could happen when it is dropped or soaked. This could also happen when the buttons have worn out or damaged. If this is the case, you will have to replace the key fob, or take it to a professional to repair it.
The key fob is made with rubber seals to stop water from entering the chip inside. However, it could be damaged when exposed to prolonged water or submersion in saltwater. This can be caused by swimming at the beach or in an unexpected rainstorm.
If you have been unable to repair the key fob of your Seat Ibiza, and you have tried everything to fix it and still haven't succeeded, you might need to buy a replacement. It is usually affordable depending on the model and make of your vehicle. It's not easy to install. You'll need to learn how to program the new key, so you should contact your dealer if possible.

In rare instances when the key fob has stopped functioning, even though all other steps have been taken (including replacement of batteries or reprogramming) it could indicate a fault with the receiver module. This is a small black box inside the key fob that sends the signal needed to control the keyless system in your car.
Dead coin batteries are a typical reason for receiver modules not working. If this is the situation, the coin battery should be replaced first. Make sure the new battery has the same size specifications, voltage and specification as the previous one.
Another issue that is common is water damage. If the fob was exposed to clean water, such as rain or tap water then this shouldn't be a problem. However it is the case if the water was dirty and soapy, or salty or corrosive, it may have damaged the chip. It is advisable to take the fob apart and inspect the mechanical parts for signs of corrosion or damage before trying to use it again. It is also important to examine the wiring and making sure it is properly connected.
Radio Interference
If the key fob's signal is interrupted by interference, it can prevent the vehicle from responding to the remote control. This could be due to many things, including radio transmissions from other devices operating on the same frequency band as the key fob. Signals that are too strong might also cause the signal to be distorted.
The most common cause of the key fob that does not function is a dead coin-cell. It is important to check the battery first. If the key fob had its battery replaced recently, but the range has diminished, this is an indication that the battery is exhausted.
It is recommended that you only make use of new batteries for replacement and to ensure correct voltage and size. It is important to ensure that the direction of the polarity is the same direction as the battery when it is put in. This will help to avoid damage to the electronic chip inside the key fob. If the battery has been damaged by water, the chip may require cleaning with isopropyl or electronic cleaner.
