You can lock and unlock the door by the button under the intake boomerang which many don’t know. Long as you have the fob, just hit the button as if you’re going to open the door and it’ll lock if you’re exiting and leaving, just like coming to the car and getting back in. The rear hatch extension is called ‘Service Mode’. I have the Paragon struts that auto open into service mode. Also radar detectors can be plugged into the rear view mirror with a phone Jack for power.
I recommend testing the C8 key. My battery went dead one week after delivery. When I tried to use the key, it turned but did not open. I had to have a tow service access the emergency floor latch with a very long rod and using an inflatable tool at the window. Stressed to da max.
Is there a way to link the power folding mirrors to the lock button on fob? Seems like an obvious option…auto fold mirrors for locking and then fold out when unlocking
@SK-pn1pe Yes. My side mirrors fold when I lock using the fob. I think ota on the 2nd press of the fob....I think it's something you can set up in the vehicle settings
Hard wire your radar from mirror, down the A pillar, under the dash, behind the center console and hard wire it to the 12 volt plug in. DO NOT plug in mirror for power! Will throw codes. And it looks better. Words of wisdom from a GM ASE Certified Master Technician over 40+ years.
I’ve been lucky so far, so far only four months using the mirror as my power source 🤞 but the C8’ are so finicky anything could happen at any time for any reason or no reason at all, you might want to add that as a modifier to your statement of best way to do it
Great to the point video! Question, when you are in the car and your wife is in the car with the other key fob, how does the car know which driver settings to use? Does it know which fob is closer to the steering wheel?
My dark one was set to #2 driver. I just kept the light one for #1 (myself) and the dark one was set up at the factory as #2, so that will be the spare or wifey for me. I just want to keep it simple and not waste Mt time reprogramming the dark one to be #1.
Please differentiate your secret tips, because coup’s and HTC’s are not exactly the same, example the trunk lid works the way you showed only on coup’s not HTC’s
You can buy an aftermarket keyboard that is identical to the factory and any dealer or some locksmiths can program the new key fob. I paid $200 for a spare fob for my TRX as it came with only one when I bought it. I found someone on Facebook and he programmed the new key fob, $200 for fob including programming.

Thanks Joseph...I just learned something new. Thanks for sharing.
Thank you
I did not know about the window feature!
Those aviator glasses are like Sleepy Joe’s! Good video.
❤Thank you for sharing this God bless you

Love your video ❤
Did you try the keyhole behind the license plate?
@@SerhansGarage in GM’s infinite wisdom probably to save $.32 they’ve eliminated the key access behind the license plates on the 2024 C8’s
Good video, I have a C8 and didn’t know about the setting
Thanks man, service mode was a great tip

Awesome…I just haven’t dug into it far enough. Just got car, thanks man!
My rear trunk won’t open, like it’s stuck. What manual way can I get it opened? Or does it have an electrical lock I have to disable before it opens?
The key lock is behind the license plate. Are you using the fob, the button in the bumper and the driver door and all 3 don't unlock the trunk?

Service mode is acc mode
Great to the point video! Question, when you are in the car and your wife is in the car with the other key fob, how does the car know which driver settings to use? Does it know which fob is closer to the steering wheel?
Thank you. The fobs are set in priority order, so Driver #1 settings will override the fob for Driver #2
Makes sense. Thanks!
It's smart that's how
is the dark one the #1 or just whichever one you set first?
My dark one was set to #2 driver. I just kept the light one for #1 (myself) and the dark one was set up at the factory as #2, so that will be the spare or wifey for me. I just want to keep it simple and not waste Mt time reprogramming the dark one to be #1.
Clarification of getting into service mode. You must have foot off the brake when pressing the start button. Otherwise the car will start.
How do I find elevations on the gps. I have a c8 3 lt. thanks, david
Does the 12v outlet on passenger side turn off when the car is turned off.?
Yes. Only the 12v outlet in frunk is always hot
Boys and girls!

How can these be hidden features if they are in the owners manual? People just need to read it.
True but no one reads every page of the manual. I'm just showing the less known features to help other C8 owners.
Like who reads the manual esp when you have CZcams plus we see you click lol.✍️
Oh c’mon, nobody does.
Yes read because forum some forum members would rather tell you to read it than help you
Hidden features? 😂
Some C8 owners are not aware of these less known features. It's all in the manual but no one reads those! Thanks for watching
Anyway to get a key fob under 700 bucks

Nope works great for my Valentine One
