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

Take a photo or note the position of the old battery within the circuit before you remove it. This will allow you to install the new battery in the same way. The majority of Hyundai smart keyfobs use the CR2032 batteries, which are sold at most stores or online. Once you have the battery in place, close up your key fob and then test it to determine if it's working again.

Contacts

If your Hyundai keyfob suddenly stopped working and you haven't dropped it, there might be a problem with the internal chip. The receiver module in your vehicle relies on radio frequency signals to communicate with the remote control, therefore in the event that this signal is disrupted by nearby transmitters or objects, it might cause the key fob to not function properly.

If you're looking to find a clever way to unlock, lock, and start your car during your Reno commute, you should consider the Hyundai I30 key programming Digital Key system.

First, take note of the way that the old battery is placed within the circuit board, or snap a picture. This will allow you to place the new battery in the same spot.

Water Damage

The key fob comes with rubber seals to protect the chip's electronic components from water. If it is able to withstand a short splash from a washing machine or a brief immersion in a light rain, it's unlikely to get damaged. However, if you've dropped it in a ocean or pool, the water can penetrate the seals and cause damage to the circuit board, which is costly to repair.

The first step is drying the key fob completely. It can be done in a variety of ways. You can put it in a bag with silica packets to soak up the moisture. You can also cook rice uncooked, but be careful not to be near it while it's still damp. This could contaminate its internal components.

It's a great idea to keep an extra key fob to ensure you can drive your car while waiting for your repaired key.

Fault Diagnosis

It can be difficult to determine the cause of a problem when your check engine light is flashing and you have a fault code. This is why an OBD diagnostic scanner is usually known as an OBD 2 (or OBD 2 in the UK). They are available in Bluetooth models that connect to your phone or standard models with readers that are connected to the socket.

One of the most common problems with i20s is the throttle position sensor (TPS) becomes defective. The sensor is responsible for determining 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 malfunctioning throttle position sensor can result in lower engine performance, jerky acceleration and RPM variations when driving.

Transmission problems are a common issue for the i20s. The transmission is a complex component with a variety of gears that work together to transfer power from the engine. Over time the friction between gears could cause the transmission to suffer failure. Signs of a malfunctioning transmission include clunking or grinding sounds and an abrupt acceleration.

Spark plugs are another area of concern for the i20. Spark plugs that are defective can cause engine damage by not sending enough sparks to every engine. If unchecked the damaged spark plug could cause serious and expensive engine damage.
