Retrieving the mechanical key
Retrieving the mechanical keyKia has used a flip key key fob since 2015 and they remain in use today (2025) in some models. The mechanical key is found by pressing the chrome button on the end opposite the key ring. The mechanical key is released and remains attached to the fob.
To use the most common Kia 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).
Kia added a new fob in 2022 that features all the the buttons on the side (right). The button at the very top — that is, the one closest to the key ring end — is the one to push in order to release the mechanical key.
If a key hole is visible, use the key to unlock the driver’s door.
Hidden Keyholes
Two Piece Door Handles
Starting with the 2014 Cadenza and K900, the manufacturer adopted the hidden keyhole trick. The Optima and Sportage were added in 2016. These models all feature a two-piece door handle. As shown in the image to the right, 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).
Pulling the cap while holding some upward pressure will work best. There is a black button in the slot that is being pushed up with the key in this move and the cap is immediately to move!
A “hybrid” of this was introduced in 2024 in the Sorento and Telluride. 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 right, 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.
And yes, with the two-piece handle one way or another you must pull a piece of your car off, but its ok! The cover will come off exposing the keyhole.
One Piece Door Handles
Kia EV6 vehicles feature a flush door handle. A push on the front of the handle will rotate the rear part outward. Then pull the handle out as far as it will go. The key hole is immediately visible (right). The mechanical key can be inserted and turned to unlock the vehicle.

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).
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.
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.
