Is the airbag still active even when deactivated by key?

Just a quick question out of the blue:

A friend often disables the passenger-side airbag using the key fob because of the child seat.

However, while reading the last error code, I came across something interesting.
Why is there a second initiator for the airbag?
Is someone unreliable?

or, in the event of an extremely severe crash, could the airbag still deploy even if it has been deactivated?

Igniter for passenger-side airbag.
Zünder 2 für Airbag Beifahrer :vermutlich der deaktivierte Zünder,und der andere???

Audi A4 B8, approximately 2011 or 2012.

I sent him a message to the customer service department to inquire about it. However, I rarely get in touch with him directly, so I'm posting this question here instead.

Also, here's the translation:

"Does driver 'Zünder' also have a second car, possibly named 'Zünder 2'?"

In airbags that use gas generators with two stages, the two propellant charges are activated sequentially and with a time delay. Depending on the severity and type of accident, the airbag control unit determines the timing between the two ignitions. The interval can vary between 5 milliseconds and 30 milliseconds depending on the vehicle.

It just needs two triggers to set it off...

It involves a two-stage activation process. The bag is initially filled only "slightly" and then tightened with a slight delay.

At least in the Passat 3C, the two-stage airbag was only available in the first model year. It is speculated that it was subsequently improved to the point where a single-stage airbag was sufficient.

I am not aware of any scenarios (such as low speed, low impact energy, etc.) in which only one stage is activated.

However, it is certain that if the airbag is deactivated, not even a single stage of the airbag system should be deployed. In the case of a rear-facing car seat, this would be fatal.

Greetings.
Sure.

Here is the translation of the text from German to English:

"Guste" means "gust" in English. It refers to a sudden and strong gust of wind.

Both stages are always ignited, but the distance between them varies (except for some systems specifically manufactured for the US market...).

Super Danke !

In der Abb.2 ist der Widerstand vom Beifahrer Airbag Zünder 2 zu groß. Nr.1 okay.

Is this related to deactivation via a key?
The warning light isn't on, at least.
Deactivating it already disables the airbag from the control unit.
Is there still going to be a mistake?

According to my understanding, the connection will be interrupted. However, I'm not entirely sure. So, you can either 1. clear the error codes, reactivate the master switch, and read the error codes again, or 2. we can wait for a more informed answer than mine .
