Battery
The most common reason for a key fob that isn't working is an inactive battery. The coin battery used in the fob is a 3V lithium button-cell battery (CR 2032). The battery can be bought at retail stores or on the internet. Replace the battery with one of the same kind size, capacity and specifications. Using a different type of battery could cause damage to the fob.
Metal clips secure the battery in the fob, which completes an electrical circuit upon activation of the remote. If these clips are loose or dirty, they might cause a short and prevent the remote from working. Clean them by using isopropyl ethanol or electronic cleaner.
To change the battery, you need to open the fob by locating an opening in the seam where you can insert a screwdriver or similar tool to break it. Remove the battery and replace it with a new one, ensuring it is installed in the same direction as the old one. The fob will then automatically close. After changing the battery it is crucial to ensure that the fob is functioning properly.
Water Damage
Water damage could be the cause of the key fob not working after you dropped it into the pool or washed it in the washer. Rubber seals protect the electronic chip on the key fob, but long-term exposure to moisture can affect the seal's quality. Water also serves as a conductor, which can lead to short circuits within the key fob.
The key fob battery can be easily replaced. By using a small flat screwdriver (or thumb nail) lift the cover of the key fob battery compartment and insert a new button cell battery CR2025 ensuring that the polarity of the battery is facing upwards. Close the key fob's battery compartment and the remote is reprogrammed to work with your vehicle again.
If you're experiencing an issue with your key fob, even after replacing the battery or reprogramming it, this could mean that the receiver module is defective. The receiver module is what receives the signals from your key fob, and then transmits them to your vehicle to control the central locking, ignition and engine.
Faulty Chip
Seat Ibiza keyfobs that stop working could be due to a chip issue. It can happen if it is dropped or wet. It could also happen if the buttons are worn out or damaged. You will either need to replace your key fob or get it repaired by a professional.
The key fob is constructed with rubber seals to prevent water from leaking into the electronic chip inside. It is susceptible to damage by submersion in salt water or exposed to water for an extended time. This can be caused by swimming on the beach, or by a rainstorm.

It can be a pain to install. It is necessary to know how to program the new key, so contact your dealer if possible.
Faulty Receiver Module
If the key fob stops working after all other steps (including battery replacement and reprogramming) this could be an indication of an issue with the receiver module. This is the small black box that is inside the fob that sends out the signal that controls the keyless entry system in your car.
Dead coin batteries are a frequent cause of the receiver module not functioning. If this is the case, the coin battery should be replaced first. Make sure that the new battery is the same specifications, size and voltage as your previous one.
Another common problem is water damage. If your fob was exposed to clean water from the tap or even rain, this should not be a problem, however if it was in dirty, soapy or salty water, then the chip may be damaged. It is recommended to remove the fob and inspect all mechanical components for indications of corrosion or damage prior to using it again. It is also important to examine the wiring and making sure that it is connected correctly.
Radio Interference
If the signal of the key fob is disrupted by interference it could prevent the vehicle from responding to the remote control. This can be caused by a number of ways, including radio transmissions from other devices that operate on the same frequency as the keyfob. Signals that are too strong can also cause the signal to become unreadable.
The most frequent cause of the key fob that does not function is a dead battery in the coin-cell. This needs to be examined first. If the key fob battery was replaced recently, but has lost its range, this is another indicator that the battery is wearing out.
It is advised to utilize a new battery for replacement and make sure that the correct size and voltage is used. It is crucial to make sure that the direction of the polarity is the same direction as the battery is inserted. This will help to avoid damage to the electronic chip within the key fob. If the battery has been damaged by water, the chip could have to be cleaned with isopropyl or electronic cleaner.
