Its History Of Seat Key
Why a Seat Ibiza Replacement Key Won't Work

A new generation of driver assists take the Ibiza to a completely new level. Travel Assist ensures that your vehicle keeps pace with traffic while Lane Assist eliminates the stress of changing lanes.

Remove the key fob cover for the battery compartment (A). Utilizing a thumb nail or flat-head screwdriver, prise upwards the cover and replace the CR2025 battery.

Dead Coin Battery

If your key fob isn't working and you're capable of reprogramming it with an entirely new code, the most likely culprit is a dead coin battery. You can replace this battery yourself within a matter of ten minutes.

Start by opening the key from the side with no metal rings. You can remove the clip-on cover using your nail. The battery that was used is pulled through the hole in the middle. Note: If you replace the battery in a wrong way, or with a battery that is not suitable, it could harm the remote. Replace the battery using the same size, voltage and specifications as the original.

In the event that the key fob you have purchased has been submerged in water, you may require cleaning the chip prior to replacing the battery. It's especially important if it was dropped into the ocean, or soapy water. This should be taken care of immediately, as exposure to water can harm the chip's electronic circuit and cause the key fob to cease working.

Worn Buttons

Seat Ibiza keys stop working the majority of the time often because the coin battery is dead. This is easy to fix and can be done in a couple of minutes. The key fob may stop working if its buttons are worn. This is a simple fix and it only requires you to swap the old key shell with an entirely new one.

It's important to note that the battery for the button should be replaced properly or damage could be caused to the key fob. It is recommended to always use a brand new battery of the same size in terms of voltage, size, and specification. It's important that the polarity is facing upwards on the new battery.

The key fob is protected by rubber seals, which will keep water out. However when you submerge the key fob in water can cause the seals to crack and damage the electronic chip inside. This usually happens if you accidentally drop your key fob into the pool or leave it in the rain. If your key fob doesn't work after replacing it or reprogramming it, then the receiver module may be defective.

Water Damage

The key fob is fitted with rubber seals that prevent water from getting to the chip inside. This doesn't stop occasional splash. If your pet has survived a wash cycle, or an ocean swim, it may have damaged the chip.

You can fix this issue by removing the battery and cleaning the chip with isopropyl alcohol or an electronic cleaner. Then, let it dry completely before putting it back. If the chip has become damaged it is necessary to replace with a brand new chip.

If your key fob still doesn't work after replacing the battery and reprogramming it, then it could be due to a issue with the receiver module. This is the part of the car that receives the signals from the keyfob and transmits the signals to the key ignition system. If you have an extra key fob you can test it. The central locking should activate and the ignition system light should illuminate. If this doesn't happen, the receiver module may be defective. This is a costly fix however it can be accomplished by a professional in your local garage.

Radio Interference

The receiver module in your key could be causing interference. This can be fixed with replacing the key with a new receiver module purchased from Seat parts.

To replace the battery, flip out the key part and then using your thumb nail or screwdriver with a flat head, gently pull upwards the key fob's battery compartment cover. Remove the old CR2025 batteries and insert a new one, making sure it has the correct polarity. You can also make use of a standard key, with the transponder chip that was transferred from the worn or damaged key. TheKeyLab can be cut and coded to your car if needed.

Faulty Receiver Module

The receiver module in the fob that you have in your keys transmits radio signals to the car. The module could be faulty when the fob stops functioning. This can be determined by using an OBDII scanner or by calling the dealer.

The remote keyless entry system is vulnerable to interference from other devices that operate on the same frequency. This could include mobile phone transmitters, electrical devices, and even a few household appliances.

If the key fob is exposed to pure tap water, it might be possible for you to clean the chip with paper towels and isopropyl Alcohol. If the fob's key is submerged in salt or soapy water or is placed on a wet floor for long periods, it will most likely result in damage and will likely require replacement.

To change the battery, use a small screwdriver with a flat head or a fingernail for prying open the compartment for the button cell batteries (B). Remove the old battery and then insert the new CR2025 battery making sure that the "+" polarity is facing upwards.
