Types of Hyundai Key Fobs

Hyundai key fobs can come in a few different forms, including a traditional key fob with buttons or a keyless entry fob that allows for keyless entry into the vehicle. Make sure you know which type of fob you have before attempting to open it.

Traditional key fobs with buttons typically have a lock button, an unlock button, a trunk release button, and a panic button. The lock button will lock all the doors of the vehicle, while the unlock button will unlock all the doors. The trunk release button will open the trunk, and the panic button will activate the alarm on the vehicle.

Keyless entry fobs allow for keyless entry into the vehicle. This means that you can simply approach the vehicle with the key fob in your pocket or purse, and the doors will automatically unlock. To start the vehicle, you simply need to press the start button on the dashboard.

In addition to the basic functions, some Hyundai key fobs may also have additional features such as remote start. This allows you to start the vehicle from a distance, which can be especially helpful on cold or hot days. Some key fobs may also have a feature that allows you to roll down the windows from a distance, which can be helpful on hot days.

Once you have gathered your tools and found a suitable workspace, you are ready to begin opening your Hyundai key fob. Remember to be patient and gentle, and take your time to avoid damaging your key fob.
