Most Hyundai smart key fobs utilize batteries that are CR2032, which are available in many stores and online. Once you have the battery installed, close up your key fob and test it to verify if it's functioning again.

Contacts

If your Hyundai Key Bexley key fob has stopped working completely out of the white of the night and you haven't lost it, you could have a problem with an internal chip. The receiver module in your vehicle relies on a radio frequency signal to communicate with the remote control, so in the event that this signal is disrupted by nearby transmitters or objects, it may cause the key fob's functionality to cease properly.

Therefore, if it withstands an accidental splash of water from a washing machine, or even a brief immersion in light rain, it's unlikely to get damaged. If you drop it in the ocean or a pool the water could get into the seals, damaging the circuit board. This is an expensive repair.

The first step is to dry the key fob completely. You can do this in many ways. You can place it in a bag along with silica packs to absorb the moisture. Alternatively, you can use uncooked rice but it's crucial not to touch the key fob while it's still moist because this could contaminate the internal components.

Fault Diagnosis

If your check engine light is on and there is a fault code, it can be difficult to pinpoint the problem without the use of a diagnostic scanner typically referred to as an OBD 2. These are available in Bluetooth versions that connect to phones or standard models with an attached reader to the socket.

One of the most frequent issues with i20s can be that the throttle position sensor (TPS) develops a fault. The sensor is used to measure the opening angle of throttle valve. The data is sent to the control unit, which aids in calculating the amount of fuel needed. A malfunctioning throttle sensor could result in rapid acceleration that is jerky, fluctuations in RPM and a reduction in engine performance.

Another issue that is common in the i20s is the malfunctioning transmission. The transmission is a complex component that has many gears that interlock to transfer power from the engine to the wheels. The friction between the gears cause wear over time which can cause the transmission to fail. Sounds of grinding or clunking as well as an acceleration that is jerky can indicate the gearbox being damaged.

Spark plugs are a different 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 every cylinder. A damaged spark plug could cause costly and severe engine damage if ignored.
