Retrieving the mechanical key
GM makes three key 
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.
For the rectangular style fob or transmitter press the thin button near the bottom of the transmitter (remote control or ‘clicker’) used to remove the mechanical key. Do not pull the mechanical key out without pressing the button.
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.
Getting Inside
If a key hole is visible at the back of the driver’s door handle, simply insert the mechanical and turn, and you’re in.
Beginning with the 6th generation Corvette introduced in 2005 and adding the Cadillac CTS and ELR Coupes, no external door handle is obvious, and thus no backup entrance option. See below.
Then in the 2013, the Chevrolet Impala and followed by eight additional models the by 2017, the key hole was hidden. Sadly, more and more General Motors products will likely feature this unnecessary change going forward.
Impala, Tahoe, Suburban, Malibu, Cruze, Camaro, Volt, Bolt
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).
Push it as far upwards as possible and hold that upward pressure. Then pry outward. And yes, you WILL feel like you are prying off a piece of your car! Move the cap rearward revealing the key cylinder. Now the mechanical key can be used in the cylinder. Look for a video here to help.
To replace the cap, insert the two tabs at the back of the cap between the black seal and the metal base. Pull the door handle out to the door open position and move the cap forward and press to snap it into place. You can then release the door handle.
Blazer EV
Blazer EVThe new Blazer EV offers a “twist” on a very similar cap. There is still a slot on the underside of the handle, but the cap is only about a 1/4 inch thick. Insert the mechanical key into the slot and turn it to release the cap. It can then be pulled away.
To replace the cap, insert it back into the grooves on the door handle. Push down on the cap until it clicks into place.
Remember, getting in the car is most important. If you have difficulty replacing the cap, don’t. Let your dealer do it when you get a new battery for your Key FOB!
Corvette
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).
Pull this release lever and the driver’s door will unlock, unlatch and open slightly and you’ll be in!
We have videos for the coupes here.
