Installing new battery
Welcome to the forum…
OK??? Sorry to be so blunt, but none of us have a crystal ball that is currently working…

Tip #1… ALWAYS remove the negative battery terminal FIRST.
Tip #2… No NOT mix the 2 cables… red to Positive, black to Negative. Take a picture of the original positioning and then compare BEFORE you reattach them.
Tip #3… If you break the battery hold down, buy a replacement, don’t just rely on gravity.

You’re going to need to know how to reset the anti-theft system once the new battery is installed.

Would using one of those battery power maintainers (what are they called?) keep the anti-theft system powered?
Yes.
Plugging a Memor-eze memory saver into a power port that’s hot all the time will prevent computers, anti-theft, radio presets etc from losing their programs when the battery is disconnected.

Additionally, the OP is likely to lose his radio station pre-sets, as well as the memory settings for the power seats if he doesn’t use a memory saver while the battery is disconnected. And, the performance may be a bit lumpy for a few minutes until the car’s computers re-learn the OP’s driving patterns.
Wearing safety glasses is never a bad idea when working with batteries.
That’s the problem, finding a port that is powered all the time. Mine aren’t so the dang thing is useless but I’ll sell cheap. There is a type that plugs into the obd 2 port that I think would work better. But you still have to connect it to a 12 volt battery or power source from what I have read. Not a problem for me but may be for others. Don’t know if a 9 volt would work or not. I’m getting close to the point where my batteries should be replaced before winter so I’ll have to decide.
I don’t have anything I need a battery saver for but I would think a 12 volt battery harger would work the same way.
Computers/modules need 5 VDC or more to keep their memory alive.

I have and have used many times one like Tester showed… I also have a socket with alligator clips on the end that I made years ago, that worst case, can be used on the battery cable ends with the 9V battery saver plugged into it…
Yeah I think the last time I just hooked the charger up to the battery cables but they are so short it was hard to keep them on. Jus lookin for an easier way. Maybe I can check for a connection point a little farther down the line.
This is the one I use now.
Still uses a 9 volt battery, but plugs into the diagnostic port instead.

I like that, don’t have to worry about whether the power port/cigarette lighter is powered on with the key out. The diagnostic port accepts the power without the key, correct?
I have a 2011 Camaro and I have replaced the battery twice. Neither time did I need any procedure to reset anything or keep the radio presets.
Well, aren’t you the lucky one?

Others have been frantically looking around for their secret code. I’ve got mine in two places.
I have a lot of gadgets that somehow remember how to continue to work as they have been, even after I change the battery. They must save the info in memory that doesn’t get erased. I wonder why car computers don’t use the same method, non volatile or flash memory to store information that needs to be saved when the battery is disconnected or goes dead?
