How can we enter our Hyundai car even if the SmartKey is dead? This video shows us how. The principle is applicable to most Hyundai cars, definitely to the Tucson, Santa Fe, Sonata, and Elantra. Inside the remote control, there is a hidden emergency key that will allow us to open the emergency lock located in the driver's door lock in these cases.

Let's extract it, pulling outwards, the metal part of the remote control and open the door. To start the car, simply press the start button with the key (which we will have reassembled in the meantime) and the car will start, taking us to the nearest electronics store to buy a new battery for replacement.
