How to Fix a Skoda Superb Key Fob Not Working
A malfunctioning key fob can be an inconvenience, especially since it could prevent you from getting into your vehicle or even starting the car. It's good to know that most key fob issues can be solved by troubleshooting, common sense, and some troubleshooting.
Start by replacing the battery. It's the most commonly encountered problem and can be solved within a matter of minutes.
Dead Coin Battery
The first thing to check to determine if your key fob has stopped working is the battery. If it's dead, the issue can be fixed by removing it and replace it with a fresh one, and your key fob should start working again. This is important because the batteries inside your key fob may not be very long-lasting and you may require replacement on a regular basis depending on the frequency you use it.
If the new battery does not solve the issue, there might be a second issue with the key fob, which requires professional help. Some of the common problems with key fobs include signal interference or damaged buttons, worn buttons or receiver module issues and an unresponsive 12 volt battery. To determine if any of these are the cause of the issue, it's important to have an extra key fob that functions to identify any possible causes of the issue.
The 12 volt battery in the key fob is essential for powering the onboard electronics, including the remote keyless and central locking systems. If the battery is defective or has gone out of charge then all the on-board electronics will stop working and the remote keyless system will not function. To test the 12 volt battery take it off for a short period of time by taking off the negative cable first, and then the positive cable. This will remove the remaining electricity from the circuit, and then reset it. The remote keyless system will function again.
If you have an extra key fob, you should consider reprogramming the original one to see if this solves the issue. The process for reprogramming the key fob is straightforward and involves switching on the ignition and then leaving it on and pressing the unlock button 5 times, with a one second interval between each press, and waiting 6 seconds until the horn sounds to start the coding process.
Worn Buttons
It is inevitable that your key fob will fail at some point regardless of how diligently you handle it. Fortunately, most key fob problems are not major and can be easily repaired by replacing the battery. In certain cases it is possible to replace the entire fob. However, prior to doing this it is important to ensure that the replacement has the same voltage and size as the original battery.
If you have a spare fob, you can always test it to determine if the problem is with the fob or the car. If it doesn't work it could be the fault of the vehicle and you will have to bring it to the dealer.
Over time, the buttons on your key fob are likely to wear out and break. They may stop working and then become unstable. This is more common in the event that the key fob was dropped or left out in the rain. If this is the case, pressing the buttons lightly can help to restore their functionality.
You can also try removing the battery from the key fob and then cleaning it with isopropyl alcohol or an electronic cleaner. It is also important to ensure that the metal retaining clips are clean and tight. This will ensure that the retaining clips are in good contact with each other.
Another issue that could arise is interference with signals. This can be caused by radio transmitters in close proximity, objects, or even the weather. This can cause your key fob to only function when it is close to your vehicle. This can be resolved by moving away from the source.
Water Damage
If the electronics inside your key fob have been damaged by water, it could hinder its functioning. It could stop working completely or may only work when it is near to the vehicle. Replace the battery as a first step. This is a cost-effective and easy fix and can usually be done by prying the transmitter housing with your thumb or using a flathead screwdriver.
It is crucial that the coin battery in your key fob is healthy. A damaged or dead battery can stop the key fob from functioning.
If you have an additional key fob, make use of it to determine if the problem is the receiver module in your car or whether a battery should be replaced. This will help you figure out whether the issue is with your key fob from skoda or whether it's something other that requires professional attention.
If you have tried the battery trick but still cannot get your key fob from skoda to work it could be due to a signal interference problem. This is a very common problem that can be caused by a variety of things, like other electronic devices that operate on the same frequency. Interference can be caused by bad weather or objects that interfere radio waves. This type of problem is difficult to identify in some instances because it is not always obvious. If you notice that your key fob doesn't work close to your car it could be due to a signal interference problem.
Receiver Module Issues
It's possible that the receiver module is faulty if your key fob doesn't work. This is the chip which communicates with the other modules in your car in order to lock and unlock doors. If the chip develops a fault it is likely to require replacement.
Or, it could be due to signal interference. If the transmitter of your key fob is too close to the transmitter, signals may interfere and cause it to cease functioning. This could include radio towers, TV or mobile phone antennas, or even household appliances. If you suspect this is the cause try shifting your keyfob away from any sources and see if it starts working again.
Also, make sure that the key fob's steel retention clips are in good shape and not loose or damaged. These clips hold the battery and complete the circuit. If they're damaged or broken the battery won't be able to receive power and the remote won't work. You should also replace the battery with one with the same size and voltage to ensure that the key fob is not damaged.
If your key fob won't function it could be because the keyfob has been exposed salt or water. If your key fob has been submerged in water, it's important to remove the battery and clean the chip using isopropyl alcohol or electronic cleaner. Also, ensure that the chip is completely dry prior to reinstalling it in the key fob.
Although it can be a bit of a snarl when your key fob isn't working it is important to remember that it is not the end of the world, and you are still able to use your vehicle. In fact, it's a good idea carry an extra key fob in your car just in case.
Signal Interference
Signal interference from other sources could cause your key fob to malfunction. This isn't always caused by the battery. This could be due to radio signals coming from nearby vehicles wireless devices, or even key fobs. Utilizing skoda keys locked in car TheKeyLab can help you see what's going on and figure out what you have to do to repair it.
It can be a real pain if your car key fob isn't working. Fortunately, most of these problems are relatively easy to identify and fix. In some instances, a replacement keyfob may be required.
The coin battery is the most frequent reason for the key fob not working. While it is possible for the battery to be recharged, it is often more economical to replace it.
It is also essential to make sure that the new battery is a proper fit. If you are purchasing an entirely new button cell it is a great option to choose one with the same size and voltage that your original battery. If you choose to use an unsuitable battery right size, it could damage the inside of your key fob.
Water damage, worn out buttons, or a damaged connector may cause your key fob to cease to work. It is a good practice to have an extra key fob to determine if the key fob functions. If it does, the issue could be attributed to the keyfob and not your car. If it does not it could be a sign of a more severe problem.
