What to Do If Your Seat Ibiza Key Fob Stopped Working
You should check these things if your key fob suddenly stopped working or is not locking or unlocking your car. It could be that the battery needs replacing or the electronic chip is defective.
The Ibiza is the most well-known model from Seat, vying with the Renault Clio, Peugeot 208, Ford Fiesta and Vauxhall Corsa in the supermini mainstream market. It's also an excellent value.
Battery
The most frequent reason for a key fob not working is an inactive battery. The coin battery in the fob is a 3V lithium button cell battery (CR 2032) and can be purchased at a variety of retailers and online. Replace the old battery with a new one of the same type, size and specification. The use of a different battery can damage the fob.
The battery is secured inside the fob with metal retaining clips, which complete an electrical circuit when the remote is activated. If these are loose or dirty, they can cause a short and stop the remote from working. Clean them using isopropyl alcohol or an electronic cleaner.
To change the battery, you need to open the fob by looking for an opening in the middle in which you can use a screwdriver or another tool to break it. Remove the battery and replace it with a brand new one, making sure that it is positioned in the same direction as the old one. The fob is then supposed to close itself. It is important to test the fob in order to make sure that it functions correctly after replacing the battery.
Water Damage
If you dropped your key fob into the pool, or threw it in the washing machine and it stopped working it may be suffering from water damage. Rubber seals protect the electronic chip on the key fob. However, long-term exposure to moisture can affect the seal's quality. Water also makes a good conductor that can cause short circuits inside the key fob.
Fortunately, the battery for the key fob is simple to replace. Use a small flat-head screwdriver or thumb nail to push open the cover of the battery compartment on the key fob. Replace the button-cell battery CR2025. Make sure that the polarity faces upwards. Close the keyfob battery compartment to reprogramme the remote in order that it can work with your car.
If your key fob still has issues after replacing the battery and programming it then it's possible that the receiver module has developed an issue. The receiver module is the part 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, there could be a problem with the chip within it. It can happen if it is dropped or wet. It could also happen if the buttons wear out or are damaged. If this is the case, you'll need to replace the key fob or bring it to a professional to repair it.
G28 Car Keys has rubber seals that stop water from getting to the electronic chip. It can be damaged when submerged in salt water or exposed to water for an extended time. This could be triggered by swimming at the beach, or by the rainstorm.
If you're having issues with your Seat Ibiza key fob and have tried everything to resolve the issue you may have to buy a replacement. It is usually affordable depending on the model and brand of your vehicle. However, it could be a headache 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 battery replacement and reprogramming) this could be an indication of an issue with the receiver module. This is the small black box that sits inside the fob and transmits the signal to control the keyless entry system in your car.
The most common reason for the receiver module to stop functioning is a dead coin battery. This is the first thing that needs to be replaced in the event of this happening. Ensure that the new battery is of the same size in terms of specifications, and voltage as the old one.
Water damage is another common problem. If your fob was exposed to pure water, like rain or tap water then this shouldn't be an issue. However, if the water was dirty or soapy, or even salty the water may have caused damage to the chip. It is advisable to take the fob apart and inspect all mechanical components for signs of damage or corrosion before trying to use it again. It is also important to examine the wiring and making sure it is properly connected.
Radio Interference
If the signal from the key fob is interrupted by interference, it could stop the vehicle from responding to the remote control. This can be caused by several factors that include radio transmissions from other devices that operate on the same frequency band as the key fob. The signal could be masked out by signals that are too loud in power.
The most frequent reason for key fobs that do not function is a dead coin-cell battery. This should be checked first. If the key fob has been replaced with a battery recently and the range has diminished this is a sign that the battery is worn out.
It is advised to make use of a brand new battery for replacement and make sure that the correct size and voltage are utilized. It is important to make sure that the direction of the polarity is the same direction as the battery is inserted. This will ensure that there is no damage to the electronic chip contained within the key fob. If the battery has been damaged by water the chip could require cleaning with isopropyl, or electronic cleaner.
