I want to ask the user of Bosch Range Boost.

Is this what you are referring to? This picture of my Allant has the rail installed but the battery is not on the rail.
On my Allant, the extra battery does not have a separate lock cylinder. It locks via the main battery (to remove the separate battery, you have to unlock the main or powertube battery) - so yes, it uses only one key.
On my R&M that is dual battery. Each battery has its own lock cylinder but they use the same key. On my Tern GSD which is also dual battery, they have separate locking cylinders and came with different keys - I had the cylinders changed to a keyed-alike setup. Neither of those bikes I believe are considered as having the Bosch range extender (are rather just dual battery) therefore I think you are referring to the setup on the Allant.

Thank you very much!
You have answered exactly what I want to hear!
As you said, I wanted to see what was attached to Allant.
The photos are also perfect.
I understand your explanation of using the built-in battery as a key.
I want to ask another question, what does it mean to change the cylinder to a key setting?
I know Tern GSD itself.
Sorry for talking unrelated.

No worries. The Tern GSD was unique in that it came with separate keys that were not the same for the batteries. Whereas for my Riese and Muller, I had one key that fit both batteries. There is a separate lock cylinder that the key inserts into in each battery holder.
To reduce the number of keys, I had my bike shop order new lock cylinders that were keyed-alike to my Riese and Muller. This required knowing the key-code and ordering the cylinders and new keys through the USA Abus distributor. Abus makes the lock cylinders for Bosch if I'm not mistaken. Hope this clarifies things.
I just purchased a Trek Allant 7+ S and had the Range Boost system put on as well. However, the dealer (installed) nor I can remove the Power Pack. They are thinking it's not removable. No way this is permanent. Over50, how did you remove yours?? There is no proprietary key to unlock it other than the RIB key as this doesn't tie into that lock system since it's an aftermarket accessory. And the "button" shown in the picture does not depress. We pulled, pushed, and pressed everything but it won't disconnect. Without damaging it, not sure I can remove this. I've contacted Trek and they say it should have a key and don't know why it's not disengaging. Any help PLEASE!!!

It locks via the Powertube lock (ie one lock for both batteries). You cannot remove it when the Powertube is locked. Unlock the Powertube (perhaps remove it) and you should be able to then depress the button and remove the Powerpack. If this doesn't work then I have to think the rail system wasn't installed properly. Unbelievable if Trek told you it should have its own key/lock.
Yeah it doesn’t do anything regardless if the main battery is removed or still in place. I saw that the RIB should be removed in manual. I’m not seeing how this rail system connects in anyway to the tube battery. Can you take close up photos please? I’ll take video and see if that will post on my end.

It doesn't connect directly to the tube battery. The rail attaches to the downtube and the release button has a pin that goes through the tube into the tube battery compartment (when pressed). If the Powertube is in the frame, you wouldn't be able to depress the release button because it would block the pin. Perhaps something has your release button jammed somehow? Or, I'm not sure if the shop needed to remove a bolt from the frame when they did the install. The bolt that would align with the release pin such that when you depress the release button, the pin would pass through the hole and into the frame (assuming Powertube battery not in the frame). I have the bike in an enclosed patio at the moment so I can't get good pictures until tomorrow. But I'll get it out in the sunlight and try to send some detailed/better photos. The rail has a power cable that connects to the motor at the base of the seat tube or top of the bottom bracket. It appears each battery has a separate connection. In the crappy picture attached (taken in dark conditions), you see the 3 bosses that attach the rail - picture a 4th point under the release button where the release button pin can be pushed into the frame. Maybe yours is blocked if a boss/bolt wasn't removed when the rail was installed - just guessing.
Edit - with the Powertube removed, see if you can see or feel a hole in the downtube that aligns with the Powerpack's release button.

Hard to tell in your picture # 1 whether the Powerpack's release pin is visible or whether that is a bolt/boss. But if the former, it doesn't look like it is aligned in the center of the hole. I'm attaching a few more pictures. Where you see a pin protruding into the frame, I am pushing on the release button. The pin is aligned just about dead center in a hole in the downtube which you can see in picture #4 (although focus is not great). I'm assuming there was a boss/mount that was there prior to the rail being installed. Maybe another Allant owner who doesn't have the rail installed (@Alaskan or @GuruUno perhaps) can shoot a picture of the top of the downtube. I didn't find a good photo of that part of my bike that was taken prior to the rail. But I'm thinking that if perhaps you remove the rail (I realize you can't remove the battery) enough to get a look under the portion where that release button sits that you will find that something is blocking the mechanism.
Edit: pics 1, 3 and 4 are inside the frame/battery housing and show a hole in the downtube and the release pin that is part of the release button mechanism - where the pin is protruding into the housing, I am pushing the release button with my non-camera hand:

Got some better pics now. Only pics I could get were of my inner tube and the power pack attached (since can’t remove). I actually reached out to my dealer to see if I could return this and purchase the 8+ S instead. Has better specs but lacks front shock. Since I feel they’ll have to remove this anyway to fix maybe can get it installed on a higher end speed bike. Just have to find out if a suspension fork can be and how difficult it is to get one installed. Nothing high end but comparable to the one in my 7+ S
