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

Close your key fob after you have installed the battery and testing it.

Contacts

If your Hyundai keyfob suddenly stopped working and you didn't drop it, there may be a problem with the internal chip.

If it is able to withstand a short splash from a washing machine, or an a short immersion in light rain it's unlikely to get damaged. If you drop it in a pool or ocean, the water could penetrate the seals, causing damage to the circuit board. This is a costly repair.

The first step is to dry the key fob completely. It can be done in a variety of ways. You can put it in a bag with silica packs to absorb the moisture. You could also use uncooked rice Be careful not to contact it while it's still wet. This could contaminate its internal components.

Diagnostics of a fault

It isn't easy to pinpoint a problem if your check engine light is flashing and you have a fault code. This is why the diagnostic scanner is commonly known as an OBD 2 (or OBD 2 in the UK). They are available in Bluetooth models which connect to your phone or standard models that have an attached reader to the socket.

One of the most frequent problems with i20s is the throttle position sensor (TPS) becomes defective. This sensor is responsible for measuring the opening angle of the throttle valve. This information is sent to a control unit, which aids in calculating the amount of fuel required. A malfunctioning throttle position sensor can result in reduced engine performance, jerky acceleration, and RPM fluctuations when driving.

Another issue common to the i20s is the malfunctioning transmission. The transmission is a complex part with a variety of gears that mesh together to transfer power from the engine to the wheels. In time the friction between the gears could cause the transmission to suffer failure. Sounds of grinding or clunking as well as jerky acceleration are symptoms of an inefficient gearbox.

The spark plugs on the i20 are another common problem area. A defective plug can cause damage to engines by not sending enough sparks to every cylinder. If unchecked a damaged spark plug could cause serious and expensive engine damage.
