The No. One Question That Everyone Working In Replacement Seat Key Should Be Able Answer
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, there are a few things to check. It could be that the battery needs to be replaced or the electronic chip is faulty.
The Ibiza is the most well-known model from Seat competing with the Renault Clio, Peugeot 208, Ford Fiesta and Vauxhall Corsa in the supermini mainstream market. It's also a great value.
Battery
A dead battery is the main reason why a key fob ceases functioning. The coin battery on the fob is a 3V lithium button cell battery (CR 2032) and can be bought at many retailers and online. Replace the old battery with one that is the same size, model and specification. If you use a different battery could damage the fob.
Metal clips secure the battery within the fob, and complete an electric circuit upon activation of the remote. If these are loose or dirty, they can result in a short circuit and stop the remote from working. Clean them using isopropyl alcohol or an electronic cleaner.
To replace the battery, open up the fob by locating an opening between the two sides in which you can use a screwdriver or another device to pull it apart. Remove the battery and replace it with a new one, ensuring it is fitted in the same direction as the previous one. The fob will then be shut automatically. It is crucial to test the fob to be sure it works properly after replacing the battery.
Water Damage
If you dropped your key fob into the pool or put it into the washing machine and it stopped working, it might be suffering from water damage. The electronic chip inside the key fob is protected by rubber seals, but prolonged exposure to water will affect the quality of these seals over time. Water also serves as a conductor that can cause short circuits inside the key fob.
The key fob battery can be easily replaced. With a small flat-head screwdriver (or thumb nail) break open the cover of the key fob battery compartment. Insert a new button cell battery, CR2025. Ensure that the polarity is facing upwards. Close the keyfob's battery compartment to re-programme the remote so that it is compatible with your car.
If you still have issues with your key fob despite replacing the battery or reprogramming it, you could be experiencing issues with the receiver module is defective. The receiver module is what receives the signals from your key fob, and sends them into your vehicle to control the central locking, ignition and engine.
Faulty Chip
Seat Ibiza keyfobs that stop working could be due a chip problem. It could happen when it is dropped or soaked. It can also happen if the buttons are worn or damaged. If this is the case, you'll have to replace the fob or send it to a specialist to repair it.
The key fob is fitted with rubber seals to prevent water from getting to the chip. It could be damaged when it is submerged in salt water or exposed to water for a long time. This could be triggered by swimming on the beach or in a rainstorm.
If you've been unable to repair your Seat Ibiza's key fob and have tried every method you can think of to solve the issue the best option is to purchase a new. It is usually affordable depending on the model and make of your vehicle. However, it can still be a pain to install it. You'll need 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 replacing batteries and changing the program) this could indicate a problem with the receiver module. It's a small, black box within the key fob which sends the signal needed to control the keyless system in your car.
A common cause for the receiver module to cease working is a dead coin battery. This is the first thing that needs to be replaced in the event of this happening. Make sure that the new battery is the same size, specifications and voltage as your previous one.
Water damage is a different issue. If your fob has been exposed to clean tap water or rain this shouldn't cause an issue. However, if seat key transponder programming was in the presence of soapy, salty or dirty water, then the chip inside might be damaged. It is recommended to take the fob apart and examine all mechanical parts for any indications of corrosion or damage before attempting to use it again. It is also important to examine the wiring and ensuring it is correctly connected.
Radio Interference
If the key fob's signal is distorted by interference, it can prevent the vehicle from responding to the remote control. It could be caused by a number of things that include radio transmissions from other devices that operate on the same frequency as the key fob. Signals that are too strong might also cause the signal to be distorted.
The most common reason for the key fob that does not work is a dead coin-cell. It is important to check the battery first. If the key fob has been replaced with a battery recently, but the range has decreased it is a sign that the battery has worn out.
It is recommended to only make use of a brand new battery for replacement and ensure that the proper size and voltage are employed. It is also recommended to ensure that the battery's polarity is in the same direction when it is placed. This will prevent damage to the electronic chip that is inside the key fob. If the battery has been damaged by water the chip may need cleaning using isopropyl or an electronic cleaner.
