What to Do If Your Seat Ibiza Key Fob Stopped Working
Examine these points if your key fob suddenly stopped working or isn't locking or unlocking your car. It could be that the battery is in need of replacement or the electronic chip may be defective.
Seat's most popular model is the Ibiza that competes with the Renault Clio and Peugeot 208 in the supermini market. It's also an excellent value.
Battery
A dead battery is the main reason why a keyfob stops functioning. The battery inside the fob is an 3V lithium button cell battery (CR 2032) and is available in many retailers and online. Replace the old battery by a new one that is similar in size, shape and specification. If you use a different battery could damage the fob.
The battery is held within the fob by clips for retaining, which complete an electrical circuit when the remote is activated. These can cause shorts if they're dirty or loose. This will stop the remote from functioning. Use isopropyl or electronic cleaners to clean them.
To change the battery, you need to open the fob by finding a gap in the seam in which you can insert a screwdriver or similar device to pull it apart. Remove the battery and replace it with a new one, making sure it is placed in the exact direction as the original. The fob is then supposed to close itself again. After replacing the battery, it is essential to verify that the fob functions properly.
Water Damage

Water damage may be the reason behind the key fob to stop working when you dropped it into a pool or washed it in the washer. The chip inside the key fob is protected by rubber seals, however prolonged exposure to water will reduce the effectiveness of these seals over time. Water is also a powerful conductor, which can cause short-circuits inside the key fob.
Fortunately, the battery for the key fob can be replaced easily. Using a small flat head screwdriver (or thumb nail) remove the cover of the key fob's battery compartment. Insert a new button cell battery CR2025 ensuring that the polarity is upwards. Close the key fob battery compartment to reprogram the remote so that it can work with your car.
If your key fob still isn't working after replacing the battery and reprogramming it then it's possible that the receiver module has developed a fault. The receiver module is the part that receives signals from the key fob, and transmits signals to your car to control the engine, ignition and central locking.
Faulty Chip
If your Seat Ibiza key fob stopped working, it could be a problem with the chip inside it. It could happen if drop it or get it wet. This could also happen when the buttons are worn or damaged. If this is the case, you will need to replace the key fob or send it to a professional for repair.
The key fob features rubber seals that stop water from reaching the electronic chip. However, it is damaged through prolonged exposure to water or submersion in salt water. This could be triggered by swimming at the beach or during a rainstorm.
If new seat car key have been unable to repair the key fob in your Seat Ibiza and have tried every method you can think of to repair it, then you may need to purchase a new. Depending on the manufacturer and model of your car this could be affordable. However, it can still be a pain to install it. You'll need to learn how to program the new key, so contact your dealer if possible.
Faulty Receiver Module
In rare instances when the key fob stops functioning and all other steps have taken place (including replacing the battery or reconfiguring) it could indicate a fault with the receiver module. It's a small black box in the key fob which sends the signal to control the keyless system in your car.
The most common reason for the receiver module to stop functioning is a dead battery for the coin. This is the first thing that should be replaced when this happens. Make sure that the new battery has the same specifications, size and voltage as the old one.
Water damage is another typical issue. If your fob was exposed to clean water, such as tap or rain water then this shouldn't be an issue. However in the event that the water was dirty, soapy, or salty or corrosive, it may have caused damage to the chip. It is recommended to open the fob and examine all mechanical parts for any signs of damage or corrosion before using it again. Examine the wiring to be sure it's connected correctly.
Radio Interference
The vehicle might not respond to the remote control if the signal of the key fob is not functioning. This can be caused a variety of ways, including radio transmissions from other devices that operate on the same frequency as the keyfob. Signals that are too strong can also drown out the signal.
The most common reason for a key fob that does not work is a dead coin cell battery. It is important to check the battery first. If the key fob had its battery replaced recently and the range has decreased this is a sign that the battery has damaged.
It is recommended to only use new batteries to replace and to ensure correct voltage and size. It is important to make sure that the reverse polarity is in the exact direction as the battery is inserted. This will protect the chip in the key fob. If the battery has been damaged by water, the chip may need to be cleaned with isopropyl alcohol, or an electronic cleaner.
