This could be caused by the battery being dead or water damage, or even signal interference. Battery Hyundai has developed the smart key fob for their vehicles that enables users to perform a variety of remote functions including locking and unlocking doors, starting your vehicle, and even triggering panic buttons.

Water Damage (Image: [[https://www.thekeylab.co.uk/wp-content/uploads/sb-instagram-feed-images/311170119_2306394586188303_2849487588620745484_nlow.jpg|https://www.thekeylab.co.uk/wp-content/uploads/sb-instagram-feed-images/311170119_2306394586188303_2849487588620745484_nlow.jpg]])The key fob features rubber seals to shield the chip inside from water. So, if it survives 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 in a pool and the water sank into the seals, causing damage to the circuit board. This is an expensive repair. The first step is drying the key fob completely. It can be done in a variety of ways. It can be placed in a plastic bag containing silica gel packets which will drain the moisture of it. Or, you could use rice that has not been cooked, but it is important not to contact the key fob when it's still wet, as this could contaminate the internal components. You can also clean the contacts of the circuit board using isopropyl or electronic cleaner. If, however, the chip is fried then it's probably best to accept that you'll require a new key fob. Replacing the battery on the Hyundai key fob is straightforward and usually not messy. You can follow an YouTube tutorial or the owner's manual to guide you through the procedure. It is a good idea to keep a spare key fob on hand so that you can continue driving your vehicle while you wait for the repair key to arrive. Troubleshooting If your check engine light is on and the fault code is present, it may be difficult to identify the issue without the use of a diagnostic scanner, often referred to as an OBD 2. These are available in Bluetooth versions that connect to your phone or standard models that have a reader attached. One of the most frequent problems with i20s is the throttle position sensor (TPS) is damaged. This 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 sensor could result in sudden acceleration, RPM fluctuations and a decrease in engine performance. 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. The friction between the gears cause wear over time which can cause the transmission to fail. Clanging or grinding sounds as well as rapid acceleration that is jerky are signs of the gearbox being damaged. Spark plugs are a different aspect to be concerned about for the i20. Faulty plugs could cause engine damage due to not giving enough sparks to each cylinder. If unchecked a damaged spark plug can result in severe and expensive engine damage.
