Retrieving the mechanical key
To use the most common Hyundai key fobs, press and hold the release button at the key ring end of the remote control or ‘clicker’ and pull the key ring to remove mechanical key. Use the key to unlock the driver’s door. They too remain in limited use today (2025).
The exception come in the form of key fobs with the mechanical release on the back, which. Hyundai began using in 2019 (right). Push the button in order to release the mechanical key.
supplying a new key fob and separate mechanical key shown to the right. This fob has spread to other models as well. To use the mechanical key, a protective cover must be removed and its handle rotated down.
trick. Several other Hyundai models have been added since, namely the Santa Fe, in 2024, and Venue. These models all feature a two-piece door handle. As shown in the image to the left, press the mechanical key into the slot found under the cover at the back of the driver’s door handle (1) and pull forward and up by hand (2).
A “hybrid” of this was introduced in 2020 in the Sonata. By 2024, it is found in the Elantra, Santa Cruz, and Tucson. The mechanical key is again slipped into a slot beneath the back of the door handle and pushed upwards. Now however, a small cover, seen in blue to the left, is slid to the side and out of the way. This should be done when the mechanical key is still inserted and pushed upward. The keyhole is then revealed.
The redesign of the Kona brings with it a new and odd door two-piece handle, as seen to the left. It still features a cap that hides the key hole, which must be removed. It looks like the others, but to get at the key hole, lift the door handle and hold it in the open position. Slip the mechanical key into the open slot in the cap from behind it and rotate the cap upwards. It will come free, exposing the key hole.
In 2019, a very different hidden key hole style was introduced in the Hyundai Santa Fe (removed in 2024), the new Palisade model a year later and the Elantra in 2021. The handle for all intents and purposes is one piece, but a small piece of horizontal trim located just behind the black entry button (arrow) is removable. Pull the handle outward. This exposes another small black button just behind the handle (2, below). Look at the handle from behind to find it.
Push the button inwards using the mechanical key. This releases the trim piece that can be swung away exposing the keyhole. The key can then be turned to unlock the car. Pull the key out before opening the door to avoid damaging the door handle.
Afterwards, the cover can be pressed back on, but your immediate concern is getting into your car.
In the Nexo, a plug protects the key hole, likely from water and debris. Use the mechanical key to pry the plug away (first image left) and then insert the key to unlock the car.
Hyundai vehicles that include a separate mechanical key include two digital options and a facial recognition option. Digital options include a pre-registered card key and a smart phone app on a registered smart phone. The card key and app can also start the car. However, facial recognition will only open the vehicle, so the key fob, card key or smart phone app will be needed to start the car.
Facial recognition is accomplished using a camera mounted in the pillar behind the driver’s door. Again, this will only allow entry and other means will be needed to start the car, so this is of limited value.
