They don't need their own rescue sub as long as they're not too proud to ask for one. That's the key if it's sunk, rather than being adrift on the surface.
Time is the key factor, in the RN used to have a system whereby a sub would advise of surfacing time before it submerged.Can't remember the time but x hours past the due surfacing time if nothing was heard they initiated a "Submiss", and after y hours a "Subsmash", something like that, was a long time ago.
Now they have to find it, and get the rescue system to the location. I am guessing in these days an incapacitated sub would release a buoyant beacon which would be picked up on satellite.

SUBLOOK, SUBMISS then SUBSUNK if memory serves. The timings of them from the scheduled surfacing time has been lost to my fading memory (Radio Supervisors course was a long time ago), I thnk SMASHEX was the practice versionCan't remember the time but x hours past the due surfacing time if nothing was heard they initiated a "Submiss", and after y hours a "Subsmash", something like that, was a long time ago.

BBC says sub had surfaced, and reported a breakdown, in its last communication. Also that the signals picked up over the weekend were not from the sub's satellite phone.

Argentine navy is reporting hearing sounds that could be from their sub. Fingers crossed.
From an organic source. https://www.theguardian.com/world/2017/nov/20/miss...Viewing the video that’s some very difficult seas to search in.
A heat source has been found by the US and vessels now investigating. https://www.standard.co.uk/news/world/heat-signatu...
Heat patch not useful.
Time running out. This would be a truly horrid way to go.

If someone was bashing a hammer on the inside of the hull from what distance would a searching ship be able to detect it?
There are a lot of factors affecting sound transmission underwater ( thermoclines, inversion layers, plankton layers ) - a hammer could be heard for a hundred miles in some conditions but be inaudible 100m away under others 
They reported a problem with the batteries; if so, they might have been running the diesel engine on the surface, with people on the conning tower and the hatch open in 30 foot waves, got broadside on and over she rolls, down-flooding through the hatch and good night Buenos Aires.
But I hope she is found with the crew alive.
