This is usually the fastest and most cost-effective method to fix the problem. Batteries for replacement are available at many stores or online. Once you have a new battery and you have it open, check to make sure the battery is in the correct place and is in contact with all connections.

Make sure you take a picture or make a note of where the old battery was placed in the circuit board prior to removing it. This will enable you to install the new battery in the same way. The majority of Hyundai smart key fobs utilize CR2032 batteries, which can be found at most stores or online. Close your key fob after installing the battery, and then test it.

Contacts

If your Hyundai keyfob suddenly stopped working and you didn't drop it, there could be a problem with the internal chip. The receiver module inside your vehicle utilizes radio frequency signals to communicate with the remote control, so when this signal is disrupted by nearby transmitters or objects, it may cause the key fob's functionality to cease correctly.

Water Damage

The rubber seals on the key fob shield the chip's electronic components from water. So, if it is able to withstand the splash of water that comes from a washing machine or even a brief immersion in light rain it's unlikely to be damaged. If you drop it into the ocean or in 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 thoroughly. This can be accomplished in a variety of ways. You can put it in a bag with silica bags to absorb the moisture. Alternatively, you can use rice that has not been cooked, but it is crucial not to contact the key fob when it's still wet, as it could cause contamination to the internal components.

Troubleshooting

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 an OBD diagnostic scanner is usually called an OBD 2 (or OBD 2 in the UK). These can be purchased in Bluetooth models that connect to your phone, or standard models with an integrated reader.

One of the most common problems with i20s is the throttle position sensor (TPS) is damaged. The sensor is responsible for measuring the opening angle of the throttle valve. This information is transmitted to the control unit and is used to the calculation of the amount of fuel needed. A malfunctioning throttle sensor will cause rapid acceleration that is jerky, fluctuations in RPM and a reduction in engine performance.

Transmission problems are a common issue for i20s. The transmission is a complicated part that has a lot of gears that work together to transfer the power from the engine. In time the friction between gears can cause the transmission's failure. Grinding or clunking sounds and rapid acceleration that is jerky are signs of an inefficient gearbox.

Spark plugs are a different issue for the i20. The problem with the plugs is that they could cause engine damage due to not providing enough sparks to each engine. If not checked an unclean spark plug can cause serious and costly engine damage.
