how much is a new key fob for hyundai to Fix a Problem With Your Hyundai i20 Key Fob

Hyundai i20 owners are able to lock and unlock their cars remotely. They can also start their vehicle ahead of time and monitor key-fob functions through an app on their smartphone.

Sometimes the key fob can stop working. It could be due to an unresponsive battery, water damage, or signal interference.

Battery

Hyundai has created a smart key fob that can be used to perform various remote functions, like locking and unlocking your doors, starting your car and even triggering the panic button. It's an ideal way to save time and energy for drivers, but can be frustrating when the system isn't working properly. If you're having difficulty getting your Hyundai i20 key fob to work properly there are a few things you can do to resolve the issue.

The first step is to test the battery. The majority of smart key fobs are powered by a coin-cell battery which can be easily replaced within minutes. This is the fastest and cheapest solution to solve your issue. You can find replacement batteries in most shops and also online. Re-open the keyfob after installing the new battery in order to confirm that the battery is in the proper location and that it is in contact with all connections.

Make sure you capture a photograph or take a note of the way in which the old battery was positioned on the circuit board prior to removing it. This will help you install the new battery in the same manner. The majority of Hyundai smart key fobs are powered by the CR2032 battery that is available in most shops and on the internet. Close your key fob after installing the battery and then test it.

Contacts

If your Hyundai key fob has stopped working completely out of the white of the night and you haven't lost it, you could be dealing with a faulty internal chip. The receiver module inside the car utilizes radio frequency signals to communicate with the remote. If these signals are interfered with by nearby transmitters or other objects the key fob might cease to function properly.

Take a look at the Hyundai Digital key system if you're looking to unlock, lock and start your vehicle during your commute in Reno. This advanced keyless system works via an app that you can install on your smartphone and allows you to share Digital Key access up to three persons. This is useful when you are giving a friend the opportunity to take a ride or leaving your vehicle for valet services.

A dead battery is the most frequent cause of the Hyundai i20's key fob not working. If yours is showing signs of dying, like slow operation or not responding at all it's time to replace the battery. While the process of replacing and opening your Hyundai key fob battery isn't a big deal, there are a few things you should know before starting. The first step is to take note of where the old battery is placed on the circuit board. You can also take a photograph. This will allow you to place the new battery in the same spot.

Water Damage

The key fob features rubber seals that protect the electronic chip inside from water. If it is able to survive a quick splash from a washing-machine, or just a brief dip in light rain, it's unlikely to get damaged. If you've dropped it in the ocean or pool, the water could penetrate the seals and cause damage to the circuit board, which can be costly to repair.

The first step is drying the key fob thoroughly. This can be accomplished in several ways. It can be placed in a plastic bag containing silica gel bags that will suck the moisture out of it. Alternately, you can use rice that has not been cooked, but it is important not to touch the key fob while it's still damp as it could cause contamination to the internal components.

Using isopropyl alcohol or an electronic cleaner may also be helpful in cleaning the contacts on the circuit board. If the chip is in danger of being damaged and you suspect it, you'll have to replace the key fob.

Replacing the battery on the Hyundai key fob is straightforward and typically not a big mess. You can follow an YouTube video tutorial to assist you with the process or refer to the owner's manual. It's a good idea to keep a spare key fob so you can drive around in your vehicle while you wait for your key to be repaired.

Diagnosis of a Fault

If your check engine light is on and the fault code is present, it may be difficult to identify the issue without the help of a diagnostic scanner, commonly referred to as an OBD 2. These are available in Bluetooth versions which connect to your phone or Shop standard models that have readers that are connected to the socket.

One of the most frequent issues with i20s is the throttle position sensor (TPS) is defective. This sensor is responsible for determining the opening angle of the throttle valve. This information is sent to the control unit that helps calculate the amount of fuel needed. A problem with the throttle position sensor could result in a decrease in engine performance, jerky acceleration, and RPM fluctuations during driving.

Transmission problems are another common issue in i20s. The transmission is a complex component that contains a number of gears that are connected to transfer power from the engine. In time friction between gears could cause the transmission to suffer failure. Symptoms of a faulty transmission include clunking or grinding noises and rapid acceleration that is jerky.

The spark plugs in the i20 are a second common problem area. Faulty plugs can cause engine damage by not giving enough sparks to each cylinder. If not checked the damaged spark plug can cause serious and costly engine damage.
