What to Do If Your Seat Ibiza Key Fob Stopped Working
Check these things if your key fob suddenly stopped working or is not locking or unlocking your car. The battery may require replacement or the electronic chips could be defective.
Seat's most popular model is the Ibiza which is a competitor to the Renault Clio and Peugeot 208 in the supermini market. It's also an excellent value.
Battery
The most frequent reason for a key fob to stop working is the battery is dead. 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 a new one with the same type, size and specification. Utilizing a different type of battery could cause damage to the fob.
Metal clips secure the battery within the fob, which completes an electric circuit upon activation of the remote. If these are loose or dirty, they might cause a short, and stop the remote from functioning. Clean them using isopropyl alcohol or an electronic cleaner.
To change the battery you must remove the fob. This can be done by inserting a screwdriver through the opening. Replace the battery with a new one. Make sure you install it in the same direction. The fob is then supposed to close itself once more. It is essential to test the fob to be sure it works properly after changing the battery.
Water Damage
Water damage could be the reason for keys that stop working after you dropped it into a pool or washed it in a washer. The electronic chip inside the key fob is protected by rubber seals but prolonged exposure to water can reduce the effectiveness of these seals over time. Water is also a powerful conductor, and can cause short-circuits to the key fob.
Fortunately, the key fob's battery is easy to replace. By using a small flat screwdriver (or thumb nail) prise open the cover of the key fob battery compartment and insert a brand new button cell battery CR2025. Make sure that the polarity is facing upwards. Close the key fob battery compartment and the remote is reprogrammed to work with your car again.
If your key fob still has a problem after replacing the battery and reprogramming it, then it's possible that the receiver module has developed an issue. The receiver module is the component that receives signals from the key fob, and transmits them to your car to control the ignition, engine and central locking.
Faulty Chip
If your Seat Ibiza key fob stopped working, it could be a problem with the chip within it. It could happen if it is dropped or gets wet. It can also happen if the buttons are worn or damaged. You will either need to replace your key fob, or repair it by professionals.
The key fob is made with rubber seals in order to prevent water from leaking into the chip inside. It can be damaged when submerged in salt water or exposed to water for an extended period of time. This can happen due to swimming on the beach or during a storm.
If you are having trouble with your Seat Ibiza key fob and have tried everything else to resolve the issue you may have to purchase a replacement. Depending on the brand and model of your car it can be affordable. However, seat car key G28CarKeys can still be a headache to install it. You'll need to know how to program the new key, so you should 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 an issue with the receiver module. This is the tiny black box that is inside the fob, which 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 coin battery. This is the first thing to be replaced in the event of this happening. Make sure the new battery has the same dimensions, specification and voltage as the previous one.
Water damage is a different problem. If your fob was exposed to water that is clean from the tap or rain this shouldn't be an issue, however when it was exposed to salty, soapy or dirty water, then the chip may have been damaged. Before you reuse the fob, it is best to open it and look over every mechanical part for signs of damage or corrosion. Verify the wiring to make sure it's properly connected.
Radio Interference
The vehicle may not respond to the remote control if the signal from the key fob is disrupted. This can happen in a range of ways, which include radio transmissions from other devices operating on the same frequency as the key fob. Signals that are too strong might also block out the signal.
The most frequent reason for the key fob that does not function is a dead coin-cell. This needs to be examined first. If the battery of the key fob has been replaced recently but it is no longer able to function it is a sign that the battery is wearing out.
It is recommended to only make use of new batteries for replacement, and to ensure the correct voltage and size. It is also advisable to ensure that the polarity of the battery is in the exact direction 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 may require cleaning using isopropyl or electronic cleaner.
