Retrieving the Mechanical Key
Subaru uses three different styles of Access Key fobs (remote controls or 
‘clickers), each of which holds a mechanical key. The rectangular shape Style 1 has a release catch (1) on the mechanical key (2) itself, very near the key ring hole, as shown. Slide the catch towards the hole while pulling on the key to remove it from the Access Key.
There’s plenty more below and video help here…
The Style 2 Access Key has an oval shape. The release for the mechanical key (2) is a simple push-button (1) on the back of the Access Key, as shown (for the record, it looks like it will slide — it won’t). Pull out the mechanical key while pressing the release button at the same time.
Finally, a limited number of Subaru models feature a Style 3 Access Key, 
which is also a more rectangular shape. Here, the mechanical key release (1) is on the side of the Access Key, as shown. Pull out the mechanical key (2) while pressing the release button at the same time.
Starting Your Subaru
Regardless of which Access Key or key fob in hand, the starting process for Subaru vehicles is the same. Hold the Access Key or key fob against the Start / Stop ignition switch with 
buttons facing out towards you, as shown. The vehicle and the Access Key will talk to each other for a few moments, after which a chime or ‘ding’ will be heard.
The Start / Stop ignition has now been switched to the “ACC” or “ON” position. With the brake pedal still depressed, push the Start / Stop button to start the engine. Like similar systems from Toyota and Hyundai, etc., you might opt to simply push the button with the key fob to start it.
Note: If you have made an attempt to start the vehicle without success, there may be residual pressure in the brake system and a new warning light may appear (left) or text 
message to Step on the Brake. Press the brake pedal very, very hard when trying to start the vehicle again to be sure that the release switch behind the pedal is engaged. Or wait a few minutes and try again.

There are three general styles of key fobs in use with Volkswagen and Audi models. With the older style shown to the right, press the chrome button on the back of the key fob (remote control or ‘clicker’) to release the spring-loaded mechanical key, which remains attached to the key fob.
Newer Volkswagen and Audi models use what they called an Advanced Key, shown to the left. The mechanical key is separated 
from the fob (or remote control or ‘clicker’) by pressing the button on the back side of the fob, shown with the arrow, while pulling on the same key ring end.
And yet a fourth key fob from Audi has a chrome button on the back, similar to the unit above, but below the chrome end. push the button and pull on the key ring end to remove the mechanical key. We saw it first in the new 2019 Q8.
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.
fob (remote control or ‘clicker’) styles, and Chevrolet uses them all. To get in the vehicle when the key fob battery is dead, a mechanical key will have to retrieved from the fob and used to unlock the car.
In next style is a flip key, shown to the left, press the unmarked chrome button to extend the mechanical key. It remains attached to the key fob. Use the mechanical key to unlock the driver’s door.
The final rounded style key fob is similar to the rectangular fob, in that the mechanical key is removed from the fob for use getting into the vehicle. However, it is similar in appearance to Style 2. To remove the mechanical key, press the button on the side of the transmitter near the key ring, as shown, and pull the key out.
Chevrolet models with traditional door handles but no obvious key holes or lock cylinders, hide the key holes under a cap at the back of the driver’s door. They include the Impala, Tahoe, Suburban, Malibu, Cruze, Camaro and Volt as well as new Bolt model. To remove the cap, pull the door handle out to the open position. Insert the key into the slot on the bottom of the cap (“3”, right).
Blazer EV
To replace the cap, insert it back into the grooves on the door handle. Push down on the cap until it clicks into place.
Corvette models are a very different animals. The C6 through C8 models have non-traditional, all electronic locks, latches and door handles, if they can be called handles at all. The C8 does have a key cylinder, but it is found in the air inlet located on the body, behind and above the left door handle. See the image to the right. Insert the mechanical key and turn to open the car.
Older C6 and C7 Corvette models, also have flush door handles (right image) with no key holes at all. They have a very different trick up their sleeves. You must use the mechanical key to open the trunk. The key hole is under the lip of the trunk lid facing the ground.
Once the trunk is open, you will find a release handle. It is along the left wall of the trunk in the Corvette (right).
(IA) (remote control or ‘clicker’) key styles. Two of the key fobs use a sliding release on the back side to release the key. Two new key fobs use a push button to release the mechanical key, and one is much easier than the other to use. Another holds the key inside the fob itself and is really difficult to remove.
To release the mechanical key blade in your IA key fob, slide the release on the back of the transmitter and pull the blade out. You can now use the mechanical key to unlock the driver’s door.
(pull is straight up and off) to access the key blade. Its awkward and may take some practice. That mechanical key can now be used to unlock the driver’s door.
To remove it, push the buttons on either side of the key fob.
It has a push button on the front of the mechanical key itself near the key ring space. Simply push the button and pull the mechanical key away from the IA key.
the 2016 Edge and later models have since been added to this list.
The Ford Expedition is updated for 2018, and features another way to hide the key hole. The door handles are a single piece. The key hole is easily exposed by simply pulling the driver’s door handle. It is seen angled outward at the back end of the handle. Insert the mechanical key and turn clockwise. Remove the key and release the handle. The door will open on the next pull. Note that the alarm will sound in a minute or so if the car is not started in time.
GT
Competition Series GT, the key hole is on the top of the hatch.
The new all electric Mustang Mach E uses electronic latches. A button above the door handle (right) is pressed and the door pops open. If the key fob is dead, the vehicle offers is no opportunity to use the mechanical key to get inside. However, the car can be accessed with an app on your smart phone or using the keyless entry code panel on the door post.
Retrieving the mechanical key
The Key Fobs used in models built after 2010 are sleeker and rounded (see the image to the right) but work the same way. Slide the mechanical latch at the top of the back of the Fob to the side and pull the emergency key out with your free hand.
Even newer models, including Ram trucks, use an updated, flatter version of the key fob. The button is on the side, as denoted by the bottom arrow. The mechanical key is removed by once again pulling on the key ring end with your free hand.
Think You Locked Your Keys in the Trunk? Maybe Not…
Locked Your Keys in the Trunk?
In the world of Push Button or Keyless Start cars, three calls are commonly received by service departments and roadside assistance operators: lock outs, dead key fob batteries and keys “locked” in the trunk or behind the rear hatch.
The third, keys locked in the trunk or storage area, is usually a conceptual problem that is a result of the nature of “locked” when it comes to modern push button ignition systems.
And of course the length of the explanation highlights one of the many problems associated with advanced technology. Perceived as user-friendly, the details can be more than confusing.
So first, assuming, and yes we hate to use that word, that the battery in the fob is strong, closing the trunk with the fob inside does not lock your keys inside. Just as a driver can approach the car with the key fob in a pocket or purse and open a door with just a touch, there is also a touch spot or pad for the trunk.
The difference is, of course, that a door has a handle to pull while a trunk does not. Thus a sense of panic can easily arise in a driver who has not routinely opened the trunk using the touch pad. Feel for it – it will generally be a raised or depressed, rubberized bit above the license plate. It is not visible unless you bend over and look for it.
This takes us to the nature of “locked” on push button systems. A driver steps from his or her car and presses the lock button on the fob. The locks engage. However, he or she can approach the vehicle at any time and open it with just a touch, all because the vehicle is in constant communication with that key fob. The same is true for the trunk, even with the fob inside the trunk.
So is the vehicle locked?
Well yes – and no! If the driver is within range, anyone can walk up to vehicle and open it. However, most vehicles make it possible to lock all the doors from the inside, which overrides the touch system.
This can result in a lockout, if the interior lock switch is engaged when exiting the car – and leaving the keys inside. This is roadside assistance time, unless you are fortunate enough to have OnStar, or an equivalent service.
So just to confuse things further, many manufacturers have included a trunk lockout switch, usually located in the glove box. This allows a driver to lock the trunk with the switch, then manually lock the glove box and hand the key fob to a valet while keeping valuables protected. If that switch is engaged and the keys are in a closed trunk, its roadside assistance time again!
Truly though, in the vast majority of situations, if you have dropped the keys into the trunk and closed it, relax. If you have a push-button start system, simply touch the pad above the license plate or on the lift handle of your rear hatch and the trunk lid or hatch will pop open.
