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.

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.
