Two methods exist in Nissan and Infinity vehicles. Some models use method 1. In this case, insert the Intelligent Key in the port provided. It will be found to the left of the steering column. It might be horizontal (first image) or vertical (second image).
If an attempt is made to start the vehicle with a discharged Intelligent Key, a guide light will illuminate at the port. Insert the key fob with the buttons up in the horizontal 
port or with the buttons facing the door in the vertical port. Make sure the key ring side is out.
Once the key fob is inserted, the vehicle can be started as normal by pressing the Start / Stop ignition button while depressing the brake. Note that the port does not recharge the fob’s battery.
If a port does not exist, method 2 comes into play. Simply touch the ignition switch with the Intelligent Key (a chime will sound). Push the ignition Start / Stop button while depressing the brake pedal within 10 seconds after the chime sounds to start the engine.
And finally, in the Infiniti QX30, the Start / Stop button appears to ‘float’ above the dashboard. Pull it away exposing the ignition switch. If necessary the tip of the mechanical key can be used as a pry bar.
Please, please, do NOT try this if you do NOT have a tapered key as shown above! Insert the tapered end of the key fob into the switch and turn to start the car old school style.
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.

Here’s the deal: Buckle up, find your model, and if the main start battery is still good, we’ll get you underway.
With Style 1 (square) key fob, used in most GM vehicles prior to 2014, and in some Cadillac CTS Coupes and Sedans ongoing, place the transmitter in the transmitter pocket at the top and rear of the center console storage area with the buttons facing towards the front of the vehicle (right).
The XLR Coupe use either a small key fob that does not hold a mechanical key or the Style 1 fob. Regardless of the key fob type, the pocket for the transmitter (or fob) is on the left of the inside of the glove box. Place the transmitter in the pocket with the buttons facing the glove box storage area (right).
In the Cadillac SRX, the transmitter pocket is located at the bottom of the console storage area (right). The new CT5 crossover uses this location as well, but using the Style 3 key fob. The spot may be beneath a storage tray, which must be lifted out, or at least beneath all the stuff that has gathered inside. Then insert the transmitter with the buttons facing up and with the vehicle in Park or Neutral, press the brake pedal and the Start / Stop ignition button as normal.
The new key style, Style 3, was introduced in 2014. In the ELR Coupe and some CTS Sedans and Wagons (later models all use this location), locate the transmitter pocket on the shelf in the front of the console, as shown to the right. It is beneath a rubber that will need to be removed, and is the shape of the transmitter. Place the transmitter in the pocket, buttons facing up, and with the vehicle in Park or Neutral, press the brake pedal and the Start / Stop ignition button as normal.
In the XTS sedan, the transmitter pocket is found in the front of the center console storage area. A storage tray may have to be lifted out. Place the transmitter in the pocket with the key ring up and the buttons facing out. See the image below. With the vehicle in Park or Neutral, press the brake pedal and the Start / Stop ignition button as normal. Check out the video 
In ATS sedan, the transmitter pocket is located in the face of the front of the inside of the center console, similar to or as shown to the right. Slide the transmitter into the pocket with the key ring facing out and buttons up. With the vehicle in Park or Neutral, press the brake pedal and the Start / Stop ignition button as normal.
In the CT6 sedan, the transmitter pocket is located in the center console as well, but in the face of the back of the console, as shown to the right. Slide the transmitter into the pocket with the key ring up and buttons facing the front of the car. With the vehicle in Park or Neutral, press the brake pedal and the Start / Stop ignition button as normal.
previously in a Cadillac model. And the Escalade went along for the ride.
Meanwhile, the new CT4, CT5 and Lyriq EV models, for no apparently good reason, use the rear cup holder as the back up start location. Again, make sure the cup holder is empty and that the key fob’s buttons are facing up. With the vehicle in Park or Neutral, press the brake pedal and the Start / Stop ignition button as normal to start the vehicle.
In the XT5 and XT6 SUVs, clear away anything being stored in the center console. At the bottom near the back, there is a depression shaped like the Cadillac key fob. Set the fob down in the depression with the buttons facing up. With the vehicle in Park or Neutral, step on the brake pedal and press the Start / Stop ignition button as normal.
pocket also located in the face of the front of the inside of the center console. However, the pocket points down, as shown to the right. The pocket in the Escalade is placed to the center and a bit lower. Slide the transmitter into the pocket with the key ring facing out, buttons forward (in a Suburban we had on hand, the engine started with the buttons facing either way). It is a loose fit, so don’t be concerned. With the vehicle in Park or Neutral, press the brake pedal and the Start / Stop ignition button as normal. Check out the video

fob (remote control or ‘clicker’) styles, and two (GM Styles 1 and 3) have mechanical keys embedded inside. That key will be used to unlock the driver’s door or the trunk (yes, the trunk) and in some cases to remove a piece of the car!
The Style 3 key fob is similar to Style 1, in that the mechanical key is removed from the fob for use getting into the vehicle. To remove the mechanical key, press the button on the side of the transmitter near the key ring, as shown, and pull out the key.
Many GM models hide the key holes under a cap at the back of the driver’s door. They include the Cadillac CT4, CT6, CTS, XT4, XT5, XT6, XTS and ATS. 
key hole. The cylinder is hidden in the same place and manner, but the cap is the top, 1/8 of an inch portion. To remove it, the door handle must be pulled fully open. Then, push the cap towards the handle to release it. It may take a bit of force to accomplish this. See two videos 
Then in 2020, Cadillac came up with a whole new cap. As with the first style, there is a slot beneath the cap (right). The handle is first identified by its more curved appearance front to back and a separation near the top. Only the bottom can be removed. It is found on the Escalade and CT5.
cover frees. It will pop out about 1/8 of an inch. Remove the key – do not pry or pull with it. Once free, the cap simply swings up and can be pulled away (right).
The CTS, XLR and ELR Coupes have flush door handles (left image) with no key holes
at all. They have a very different trick up their sleeves.
We have two videos for coupes 
With the flip key key fob, the mechanical key remains attached to the fob, but several back-up locations are used. In the Buick Verano, Regal (through 2017) and pre-2014 Lacrosse, remove the cup holder from the center console in front of the storage area. This may be the entire cup holder assembly (above right), or simply a cup holder insert (below right).
Look for a notch at the top rear of the cup holders to insert a finger or tool to aide removal. Then place the transmitter in the transmitter pocket with the buttons facing up. The pocket will be shaped somewhat like the key fob.
The back up location is changed in the Regal beginning with the 2018 model year, and the car uses a newer key fob. The spot is in a narrow compartment at the front of the center console, as can be seen in the image at right. And for the first time in any GM vehicle, the spot is marked. There is an image of a padlock with lines radiating from it, meant to invoke radio waves.
For the LaCrosse in 2014, the transmitter pocket is moved into the storage area inside the armrest near the auxiliary power, USB and audio ports (right). Place the transmitter in the pocket.
The newest key style was introduced in 2014. It features a removable key. Note that there are still some flip keys in use. The Buick Encore, with exception, and Envision, until 2021, crossovers will use this spot. Simply drop the key fob into the front cup holder with the buttons up, and start the car as normal. Check out videos for these models 
The exception is the Encore GX, beginning with the 2020 model. There is a small depression at the rear of a tray on the center console that is just in front of the center console storage area. This is the back up spot. The new Envista model introduced in 2024 uses this spot as well. Drop the key fob onto this spot with the buttons up and start the car as normal, again pressing the Start / Stop button while stepping on the brake.
And the 2021 Envision finds the back up spot moved to the front of the center console storage area, See the image to the right. Inside and at the front of the console there is a small, flat depression. Drop the key fob onto this spot with the buttons facing up and start the vehicle as normal, stepping on the brake while pushing the Start / Stop button. See a helpful 
Finally, the Buick Enclave gets keyless start for the first time in 2018. The back up spot is beneath the rubber mat at the bottom of the center console. Remove the mat and place the transmitter on the fob-shaped depression that is now visible. As always, with the vehicle in Park or Neutral, press the brake pedal and the Start / Stop ignition button as normal. We’ll post more information as it comes available.
Buick uses the last two of GM’s three key fob (remote control or ‘clicker’) styles. Style 2 is a flip key, shown to the right. Simply press the unmarked chrome button to extend the mechanical key. It remains attached to the key fob.
Then came the new Envista in 2024. The key hole or lock cylinder is hiding behind an oval cap seen towards the rear of the driver’s door handle (right). It will need to be removed to expose the cylinder.
the oval cap that can accept the key (right). Insert the key into the spot and press the key inward. This will allow the cap to move. Move it towards the rear and remove it. The key hole is now visible and the door can be unlocked.
The MKS is unique in using the glove box as the location for the backup slot. It is to the far right side under the glove box door, and may be difficult to reach. Slip the Intelligent Access key down into the slot with buttons facing out and with key ring up or out. See the image.
bit.
In 2018, the Navigator location is moved to the back wall inside the center console (right). It should look like a pocket anchored to the back wall. Slip the key fob in vertically with the buttons facing forward.
beneath the rear cup holder. Remove the bottom liner from the cup holder by pulling it up by the tab (see image to the right). The slot is then revealed. Drop the fob into the slot with the buttons facing the rear of the rear of the car.
the front wall structure ( lower right). For this model, the key fob should be placed on its side with the buttons facing the back of the console.
In MKT, MKZ Hybrid (2013) and new (2017) Continental models, the slot is found near the Auxiliary, USB and power ports in the center console, like the one shown. The Intelligent Access key is slipped in with the buttons facing out and the key ring up (in one vehicle we tested, the vehicle started with the buttons facing either direction).
In the MKC and MKX (through 2015), the backup slot is to the front of center console, also found near the Auxiliary, USB and power ports, as shown. The Intelligent Access key is slipped in with the buttons facing out and the key ring up. The slot is impossible to see and you may want to feel for the ribbing at the bottom of the slot.
In 2016, the back up slot in the MKX is moved to the bottom of the center console. The Nautilus, new in 2019, uses this location as well. There is a visible depression in the console’s floor the shape of the key fob. Place the fob in the depression with the buttons up and key ring end facing forward.
In 2024, the back up slot in the Nautilus is moved to the front of the center console (image right). Slip the fob in with the buttons facing the rear.
New in the 2014 MKZ and MKZ Hybrid the backup slot is hidden under one of the cup holders.
Stress Can, Will, and Does Put Drivers in Danger
Stress Dangers
In our last post, we discussed the gap in the knowledge of automotive technology in first responders, as represented by a video from truthaboutcars.com and YouTube. It featured a man pulled over in his Tesla for having a computer mounted on his dashboard. The item is linked here.
But as we thought more about this, the video painted a very clear picture of how people tend to react to stressful situations.
In truth, it is the car’s entire instrument panel! The screen offers control of everything, as well as a view to the functioning of the car, and mapping, etc. The center console is simply not in play.
A Thank You
“Thank you 73 year old lady, 2013 mini nervous and panicked in parking lot with dead FOB yesterday. Your video heloed get everything up and running. Hard to read a manual with out reading glasses in stress situation. Thank you again.”
She describes perfectly the difficulty people face solving a problem and reading a manual while under stress. And stress is the central theme.
She identifies herself as 73, and the stress is due to the all too common key fob problem that we put a great deal of emphasis on here at DashboardSymbols.com. The video we discussed earlier puts the stress of being pulled over on full display.
Is Age the Issue?
But first we also get to once again dispel the ageism myth. The driver in the video is clearly quite young and still stutters and stammers his way through his interactions with the police officer.
This reaction to stress happens to us all irrespective of age, and returns us to our primary thesis. The relentless increase in automotive technology continues to outpace driver knowledge. And for those of you tempted to blame the driver for lack of effort, we will repeat that all of us learn by use and repetition, and if a new problem crops up, it will make little difference whether or not the driver has read about it in the manual months earlier.
And it is all too often the little things — and things that could easily be removed from the equation, taking us back to key fobs. If the battery in the fob dies, there is a back up plan, but there is no standardization. We know of and have documented exposing hidden keys holes from 15 manufacturers, a dozen variations for retrieving the standard ‘hard’ key from the fob, and over 50 distinct starting variations.
The hidden key holes are a particularly pointless exercise intended only to make a square inch of the car prettier. What it does in truth is leave drivers with dead key fobs vulnerable outside of their cars, fumbling for a mechanical key and trying to expose a lock cylinder. Will it happen on a warm summer day at home? Most likely it will be dark, rainy, cold, snowy, or in a parking garage with cell service blocked.
Make no mistake, these are safety issues and the responsibility lies with the manufacturer to make getting in to the relative safety of the car as easy as possible, and the majority of manufacturers are failing.
At the very least, once inside a manual can be consulted to get help to get the car started, but remember that stress is still in play.
Unfortunately, it will take someone getting hurt or worse, or a manufacturer getting sued before this will change, and even if it does, there will be millions of vehicles already on the road holding tight to the old ways.
