How to Start a Hyundai ix35 When the Key Fob Battery is Dead?

Mechanical key, hidden inside the back cover of the smart key. Press and slide open the back cover to reveal the mechanical key. After opening the cover, pull out the key. Use the mechanical key to open the car door, then place the smart key near the sensor. The sensor location varies by model - some have it in the cup holder, others near the push-start button. Once the vehicle detects the key, you can start the car. Placing it in the correct position allows normal vehicle startup even with a dead smart key battery.
Oh, I've experienced my Hyundai ix35 key running out of battery too, don't panic! Most smart keys come with a backup mechanical key hidden inside the key fob—just press the small button to release it. First, locate the hidden keyhole on the driver's door and use the mechanical key to unlock it. Once inside the car, don’t rush to press the start button. Instead, place the dead key near the start button or the induction area under the steering wheel—some cars even have a slot near the cup holder. Then, press the button while holding the brake. That’s how I started my car last time when the key was completely dead. When I visited the dealership to replace the battery, they advised me to check the key’s battery level regularly to avoid such awkward situations, especially since driving at night without lights can be dangerous. If this method doesn’t work, the key might be broken and need replacement, or you could visit an auto repair shop for a check. In any case, keeping a spare CR2032 coin battery in the car can save a lot of hassle.
