So have this security steel door that’s about 10cm thick and I want to install a digital lock on it.
It needs double turn to fully lock and secure the door.
Are there any products that I can buy here to retrofit it?

Nothing wrong with making it digital.
Ok, I’ll bite. 10cm thick is serious, strongroom level security. I would expect you will need to replace a bolt that takes a wheel type handle like on a bank safe.
The cheap and cheerful electronic safes use a small pin to stop that rotation, they don’t spin the lock for you, and they all have easy to overcome weaknesses for dealing with a flat battery.
An electronic lock you can buy for self installation uses the same sort of mechanism. They all have the weakness of internal power that has a back door for flat batteries etc.Secure door locks, like to access a secure room at the bank,, don’t have this. They are stuck shut from the outside if power fails, but need to be installed professionally.
And that is just a door lock, not a rotating bolt door.I’m happy to be corrected, but I haven’t seen any self-install electronic locks that offer much security, certainly not at a level where they would be anything approaching the effort of broaching a steel door.
The selection is getting better. Yale has a few that appear to offer as much security as a standard dead bolt. I think there are even models these days without an override key which you can externally power with a 9v battery if they run out of juice
Ok some more info:
It’s a front door that was imported from China and installed. Was upgraded to use 1.5mm steel and to be fire/weather resistant.
It has 6 bolts along the side/top/bottom and a centre bolt that is like a hook. First turn of the key activates the centre bolt and the second turn activates the rest.
They do make it for sale in China but was hoping to buying something local that could be used.
Edit: 10cm doors are the norm over there.
Go to Bunnings and check them out. There are lots. If you care about security make sure the override cylinder is an actual decent lock and not some f-grade joke, otherwise you might as well leave it unlocked.
Call you local locksmith that has a store and ask them.
10cm thick? Ok Scarface
10cm door?
We’re talking about a safe or Strongroom right?
Probably easier to just leave it open if you aren’t concerned with its security any more.
