Battery

Hyundai has created a smart key fob that can be used to perform a variety of remote functions like locking and unlocking your doors, starting your car and even activating the panic button. It's a fantastic feature for drivers, helping them save time and effort, however it can be a challenge when the system ceases to function properly. There are a few options you can do when your hyundai spare key i20's main fob isn't functioning properly.

The first thing to do is to check the battery. The majority of smart key fobs utilize an internal battery that is easily replaced in minutes. This is the fastest and cheapest way to solve your issue. You can purchase replacement batteries at most stores as well as online. Re-open the keyfob after installing the new battery to ensure that the battery is in the proper location and that it is in contact with all the connections.

Make sure to snap a photo or take a note of the way in which the old battery was positioned in the circuit board prior removing it. This will let you install the new battery the same way. Most Hyundai smart keyfobs are equipped with CR2032 batteries, which are sold in a variety of stores or online. Once you have the battery installed shut down your key fob and then test it to determine if it's working again.

Contacts

If your Hyundai keyfob suddenly stopped working and you weren't able to drop it, it may be a problem with the internal chip. The receiver module inside the car uses radio frequency signals to communicate with the remote. If these signals are interrupted by nearby transmitters, or objects the key fob might stop working correctly.

Consider the Hyundai Digital Key system if you want to unlock, lock and start your vehicle while you commute to Reno. This innovative keyless system functions with an app on your smartphone. It allows you to share Digital Key access up to three people. This is helpful when you give a friend an escort or leaving your vehicle with valet service.

The most frequent reason for a Hyundai i20 key fob to stop functioning is an inactive battery. If yours is showing signs of dying, such as slow operation or not responding at all, it's time to replace the battery. While opening and replacing your Hyundai key fob battery shouldn't be difficult, there are a few things you should know before starting. Take a picture or make a note about how the old battery is placed inside the circuit board. This will help you place the new battery in the same place.

Water Damage

The rubber seals on the key fob protect the electronic chip from water. So, if it survives a splash of water from a washing machine or even a brief immersion in light rain, it's unlikely to get damaged. If you've dropped it in the pool or the ocean, then the water may get through the seals and damage the circuit board, which is expensive to repair.

The first step is drying the key fob thoroughly. This can be done in several ways. You can place it in a bag along with silica packets to soak up the moisture. You can also make use of rice that isn't cooked but it's important not to contact the key fob when it's still damp as this could contaminate the internal components.

It is a good idea to keep a spare key fob on hand so that you can continue driving your car while you wait for the replacement key to arrive.

Diagnosis of a Fault

It can be difficult to determine a problem if your check engine light comes on and you have a fault-code. This is the reason why a diagnostic scanner is often known as an OBD 2 (or OBD 2 in the United Kingdom). These are available in Bluetooth models that connect to your smartphone, or standard models that have an attached reader.

One of the most frequent issues with i20s can be that the throttle position sensor (TPS) develops a fault. The sensor is responsible for measuring 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 required. A malfunctioning throttle sensor can result in abrupt acceleration, erratic RPM changes and reduced engine performance.

Another common problem found in the i20s is the transmission that is defective. The transmission is a complicated component that has many gears that work together to transfer power from the engine to wheels. The friction between the gears cause wear and tear over time, which could cause the transmission to fail. Symptoms of a faulty transmission include clunking or grinding sounds and an abrupt acceleration.

Spark plugs are an additional area of concern for the i20. The problem with defective spark plugs is that they can harm the engine by not delivering the correct amounts of sparks to each cylinder. If unchecked a damaged spark plug could result in serious and costly engine damage.
