If I remember correctly from my schooling and can translate this to ELI5.

Imagine drugs and neurotransmitters ( chemical signals) like keys and receptors as locks. When a drug fits the correct lock it opens the door and you see the drugs effect.

Benzos still function like this technically, but when it opens it's lock (a secondary lock), it works like adding WD-40 to the primary lock. Now the primary will open easier but it still needs it's key around.

In this case, the primary lock is where you get the serious problems like death.
