Digital lock : How to do ?

[Manu26]

Hello,
 
I arrive in a few hours in an apartment in London, equipped with a digital lock.
In my confirmation emails, AirBNB announced that I would receive instructions for this digital lock three days before my arrival, and that these instructions would be on my summary. But as you can see in the picture, there is no instruction ... There is a space "Digital Lock Instructions" (which is not a link since I can not click on it) but nothing... The host does not answer me either ...
With a little hope, I figured that being digital, the lock might recognize the reservation code which is a sequence of 10 letters and numbers. But I do not want to take the risk, so if someone could enlighten me, my arrival is only a matter of hours (I know, I'm a little late ...)

Thank you very much !
