What to Do If Your Seat Ibiza Key Fob Stopped Working
If your key fob has stopped working suddenly or it isn't locking and unlocking the car, there are things to check. The battery might need to be replaced or the electronic chips could be defective.

Battery
A dead battery is the main reason why a keyfob stops functioning. The battery that powers the fob is a 3V lithium button-cell battery (CR 2032). The battery can be purchased at retailers or online. Replace the old battery with one with the same type size, dimensions and specifications. Utilizing a battery of a different type can damage the fob.
The battery is encased within the fob by metal clips that hold it in place, which form an electrical circuit when the remote is turned on. They could cause shorts if they're dirty or loose. This will prevent the remote from working. Use isopropyl or electronic cleaners to clean them.
To replace the battery, you will need to open the fob. You can do this by inserting a screwdriver into the opening.

Water Damage

However, long-term exposure to moisture can decrease the quality of the seals. Water is also a great conductor, and can cause short-circuits within the key fob.
Fortunately, the key fob's battery is easy to replace. Make use of a small flat-head screwdriver or thumb nail to pry open the cover on the key fob's battery compartment. Insert a new button-cell battery CR2025. Make sure that the polarity is facing upwards. Close the keyfob's battery compartment to reprogramme the remote in order that it is compatible with your car.
If you still have problems with your key fob even after replacing the battery or reprogramming it, there is a possibility that the receiver module has failed. The receiver module is the component that receives signals from the key fob and relays signals to your car to control the engine, ignition and central locking.

Depending on the make and model of your car this could be inexpensive. It's not easy to install. It is necessary to know how to program the new key, so get in touch with your dealer.
Faulty Receiver Module
If the key fob stops working after all other steps (including replacing batteries and changing the program) this could indicate a fault in the receiver module. This is the tiny black box inside the fob that sends out the signal that controls the keyless entry system in your car.
A common cause for the receiver module to stop functioning is a dead battery for the coin. This is the first thing that needs to be replaced if this is the case. Ensure that the new battery is the same size specifications, voltage and specification that the old one.

However, if the water was dirty or soapy or corrosive, it may have caused damage to the chip. Before reusing the device, it is recommended to take it apart it up and inspect the mechanical components for signs of damage or corrosion. It is also advisable to check the wiring and ensuring it is properly connected.
Radio Interference
The vehicle may not respond to the remote control if the signal of the key fob is not functioning. This can happen in a variety of ways, such as radio transmissions by other devices operating on the same frequency as the keyfob. Signals that are too strong may also drown out the signal.

It is recommended that you only make use of new batteries for replacement and to ensure correct size and voltage. It is essential to ensure that the polarity is in the same direction as the battery when it is placed. This will help to avoid damage to the electronic chip contained within the key fob. If the battery has been damaged by water the chip might require cleaning with isopropyl, or electronic cleaner.
