Battery

Hyundai has developed the smart key fob for their vehicles. It allows you to perform a range of remote functions, including locking and unlocking doors, launching your vehicle and even activating an emergency button. It's an excellent way to cut down on time and energy for drivers, however it can be a hassle if the system isn't working properly. There are a few options you can do to fix your Hyundai i20's key fob isn't working correctly.

Re-open the keyfob after installing the new battery to make sure that the battery is in its correct position and in contact with all the connections.

Take a picture or note the location of the battery that was removed from the circuit before taking it out. This will allow you to install the new battery in the same way. Most Hyundai smart keyfobs use the CR2032 batteries, which can be found in most stores or on the internet. Close your key fob after installing the battery and testing it.

Contacts

If your Hyundai keyfob suddenly stopped working and you haven't dropped it, there may be a problem in the internal chip.

Water Damage

The rubber seals on the key fob shield the electronic chip from water. So, if it is able to withstand 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 in the pool or ocean then the water can penetrate 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 with silica packs to absorb the moisture. You can also use uncooked rice, but be careful not to contact it while it's still damp. This could lead to contamination of the internal components.

Using isopropyl alcohol or an electronic cleaner could also be helpful in cleaning the contacts on the circuit board. If, however, the chip is fried then it's probably best to accept that you'll require a replacement key fob.

These are available in Bluetooth versions that connect to your phone or standard models with readers that are connected to the socket.

One of the most frequent issues with i20s can be that the throttle position sensor (TPS) is defective. This sensor is used to measure the opening angle of throttle valve. This information is sent to an electronic control unit, which helps calculate the amount of fuel needed. A malfunctioning throttle position sensor can result in a decrease in engine performance, jerky acceleration, and RPM variations when driving.

Another issue common to the i20s is a faulty transmission. key replacement near me is a complex component that has many gears that connect to transfer power from the engine to wheels. The friction between the gears cause wear and tear that can cause the transmission to fail. Signs of a malfunctioning transmission include clunking or grinding sounds and the jerky acceleration.

Spark plugs are another issue for the i20. Spark plugs that are defective can cause damage to the engine by not delivering the right amount of sparks to every cylinder. A damaged spark plug can result in costly and serious engine damage if it is not checked.
