10 Healthy Habits For A Healthy Hyundai I10 Key
How to Fix a Problem With Your Hyundai i20 Key Fob

Hyundai i20 owners can lock and unlock their vehicles remotely. They can also start their vehicle prior to time and monitor the functions of their key fob through a mobile application on their smartphone.

Sometimes the key fob might stop working. This could be due to the battery being dead or water damage, or even signal interference.

Battery

Hyundai has developed a smart key fob that is able to perform various remote functions, such as locking and unlocking your doors, launching your car and even activating the panic button. It's an excellent way to save time and energy for drivers, but it can be frustrating when it doesn't work as intended. There are a few options you can do if your Hyundai i20's key fob isn't working properly.

The first thing to do is to check the battery. The majority of smart key fobs are powered by a coin-cell battery that can be repaired in a matter of minutes. This is the easiest and cheapest way to fix the issue. Batteries for replacement are available at the majority of stores or on the internet. Once you have a new battery in place and you have it open, check to ensure that the battery is sitting in the right position and that it's in contact with all connections.

Take a photo or note the position of the old battery in the circuit before you remove it. hyundai i10 car key cover will assist you in installing the new battery in the same manner. Most Hyundai smart key fobs utilize CR2032 batteries, available in a variety of stores or online. Once you have the battery in place and closed, you can close the key fob and test it to determine if it's working again.

Contacts

If your Hyundai key fob suddenly stopped functioning and you didn't drop it, there may be a problem in the internal chip. The receiver module in your car uses radio frequency signals to communicate with the remote control, therefore when this signal is disrupted by nearby transmitters or objects, it can cause the key fob to stop functioning properly.

You should consider the Hyundai Digital Key system if you want to unlock, lock and start your vehicle during your commute in Reno. This innovative keyless entry system works with an app for smartphones that allows you to share Digital Key access with up to three others. This is useful when you offer an individual a ride or when you're leaving your car with valet services.

A dead battery is the primary cause of the Hyundai i20's key fob not functioning. If yours is displaying signs of dying, like slow operation or not responding at all, it's time to replace the battery. While the process of opening and replacing your Hyundai key fob battery shouldn't be difficult but there are a few things you should know before beginning. First, make a note of the way that the old battery sits inside the circuit board or snap a picture. This will assist you in placing the new battery in the same position.

Water Damage

The key fob has rubber seals that protect the chip's electronic components from water. So, if it survives an accidental splash of water from a washing machine, or an evaporation in light rain, it's likely to not be damaged. However, if you've dropped it into the pool or the ocean, then the water could penetrate the seals and cause damage to the circuit board, which can be expensive to repair.

The first step is drying the key fob completely. This can be done in several ways. You can put it in a plastic bag containing silica gel packets that will suck the moisture out of it. You can also cook rice uncooked, but be careful not to be near it while it's still wet. This could cause contamination to the internal components.

You can also clean the contacts of the circuit board by using isopropyl or electronic cleaner. However, if the chip is fried then it's probably best to accept that you'll require a new key fob.

Replacing the battery in the Hyundai key fob is straightforward and usually not messy. You can follow an YouTube tutorial video to help you through the process or consult the owner's manual. It is a good idea to have an extra key fob in your side so that you can continue driving your vehicle while you wait for the replacement key to arrive.

Diagnosis of a Fault

It isn't easy to pinpoint the cause of a problem when your check engine light is illuminated and you have a fault-code. This is why the diagnostic scanner is typically called an OBD 2 (or OBD 2 in the UK). These are available in Bluetooth versions which connect to your phone or standard models that have an attached reader to the socket.

The throttle position sensor (TPS) is located in the i20, could fail. The sensor is responsible for determining the opening angle of the throttle valve. This information is transmitted to the control unit, and contributes to the calculation of the amount of fuel needed. A malfunctioning throttle sensor will cause sudden acceleration, RPM fluctuations and reduced engine performance.

Another common problem found in the i20s is the transmission that is defective. The transmission is a complicated component with a variety of gears that work together to transfer power from the engine. Over time, the friction between the gears can cause the transmission's failure. Sounds of grinding or clunking as well as the jerky acceleration can be signs of the gearbox being damaged.

Spark plugs are yet another area of concern for the i20. Spark plugs that are defective can cause damage to engines by not sending enough sparks to every engine. If they are not checked the damaged spark plug could result in serious and expensive engine damage.
