Battery
A dead battery is the main reason why a keyfob stops functioning. The coin battery used in the fob is a 3V lithium button-cell battery (CR 2032). The battery can be purchased at retailers or online. Replace the battery you have with one that is identical in size, type and specification. A battery of a different type could damage the fob.
The battery is encased within the fob by retaining clips, which complete an electrical circuit when the remote is turned on. They can cause shorts if they're dirty or loose. This will stop the remote from functioning. Use isopropyl or electronic cleaner to clean them.
To change the battery, simply open the fob by finding a gap in the seam where you can insert a screwdriver, or other tool to break it. Replace the battery with a new one.

Water Damage
Water damage could be the cause for the key fob to stop working after dropping it in a pool or washed it in the washer. The chip inside the key fob is protected by rubber seals, however prolonged exposure to water can affect the quality of these seals over time. Water is also a great conductor, which can cause short-circuits in the key fob.
The key fob battery can be replaced easily. Using a small flat head screwdriver (or thumb nail) prise open the cover of the key fob's battery compartment and then insert a new button cell battery, CR2025. Ensure that the polarity of the battery is facing upwards. Close the keyfob battery compartment to re-programme the remote so that it works with your car.
If you're still experiencing an issue with your key fob even after replacing the battery or reprogramming it, you could be experiencing issues with the receiver module is faulty. The receiver module is the part that receives signals from the key fob and relays the signals to your car in order to control the ignition, engine and central locking.
Faulty Chip
Seat Ibiza keyfobs that stop working could be due to a chip problem. It could happen if the device is dropped or gets wet. It can also happen if the buttons are worn out or damaged. It is either necessary to replace your key fob, or have it repaired by a professional.

Faulty Receiver Module
In rare cases when the key fob isn't working, and all other steps have been performed (including battery replacement, reprogramming) this may indicate an issue with the receiver module. This is a small black box in the key fob that transmits the signal to control the keyless system in your car.
Dead coin batteries are a typical reason for the receiver module not working. If this is the case then the battery for the coin should be replaced first. Make sure that the new battery is the same size, specification and voltage as the original one.
Water damage is a different issue. If your fob has been exposed to clean water from the tap or even rain, this shouldn't be a problem, however if it has been in salty, soapy or dirty water, then the chip inside may have been damaged. It is advisable to open the fob and check all mechanical pieces for indications of corrosion or damage before trying to use it again. It is also worth checking the wiring and making sure that it is connected correctly.
Radio Interference
The vehicle might not respond to the remote control if the signal of the key fob is disrupted. This can be caused a number of ways, including radio transmissions by other devices that operate on the same frequency as the key fob. The signal may be masked out by signals that are too loud in intensity.
The most common reason for key fobs that do not function is a dead coin-cell battery. This must be investigated first. If the key fob has been replaced with a battery recently however the range has diminished this could indicate that the battery is damaged.
It is recommended to only use new batteries for replacement, and to ensure the correct voltage and size. It is essential to ensure that the direction of the polarity is the same direction as the battery when it is inserted. This will prevent damage to the chip in the key fob. If the battery has been exposed to water damage the chip could have to be cleaned with isopropyl alcohol or electronic cleaner.
