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

Make sure you snap a photo or take a note of where the old battery was placed on the circuit board prior removing it. This will help you install the new battery the same way. The majority of Hyundai smart key fobs utilize a CR2032 battery which is available in many stores and on the internet. Once you have the battery in place, close up your key fob and test it to verify if it's functioning again.

Contacts

If your Hyundai key fob stopped working from the blue and you haven't dropped it, you may be experiencing a malfunctioning internal chip.

If you drop it in the ocean or in a pool the water could get into the seals, causing damage to the circuit board. This is an expensive repair.

The first step is drying the key fob completely. This can be done in several ways. You can put it in a bag along with silica bags to absorb the moisture. You can also cook rice uncooked, but be careful not to touch it while it is still damp. It could be contaminated by the internal components.

Troubleshooting

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

One of the most frequent issues with i20s can be that the throttle position sensor (TPS) becomes defective. This sensor is responsible to measure the opening angle of the throttle valve. The information is then sent to the control unit and contributes to the calculation of the amount of fuel needed. A damaged throttle sensor can cause sudden acceleration, RPM fluctuations and reduced engine performance.

Another issue that is common in the i20s is the transmission that is defective. The transmission is a complicated component made up of many gears that work together to transfer power from the engine to the wheels. The friction between the gears can cause wear over time which can cause the transmission to fail. Grinding or clunking sounds and jerky acceleration are symptoms of an unreliable gearbox.

Spark plugs are a different area of concern for the i20. Faulty plugs could cause engine damage due to not providing enough sparks to each engine. A damaged spark plug could cause costly and severe engine damage if it is not checked.
