The keys were left in the trunk - why can the car still remain locked after opening the door?

The client's name has been changed.
Let's call the client Roman. The keys were left in the trunk of the car. We managed to restore access to the driver's door, but the trunk and other doors remained blocked.
Roman was surprised:
“But if the interior is open, why does the car still not give up the keys?”
This is indeed possible.
Why one open door does not mean full access
The central locking system can have different modes. Depending on the model:
- mechanical opening of one door does not unlock the others;
- the trunk is controlled separately;
- some buttons do not work without regular authorization;
- specifications may differ in different markets.
Why the exact model and equipment is important
Even cars with the same name can have differences between:
- European;
- American;
- other versions.
The original article describes a similar case with the American-spec Volkswagen Passat B8. But from one such case it is impossible to make a universal instruction for all B8s.
Why a master should not continue experimenting endlessly
If the first step of access is completed and the trunk remains locked, the system needs to be re-evaluated. Sometimes required:
- additional diagnostics;
- information on a specific configuration;
- another specialist.
What to tell in advance
If the keys are in the trunk, say so right away. This is significantly different from the situation when the key is on the front seat.
