That’s still a problem at least in the medium term, because the US control the supply of spare parts for the missiles.
(I won’t mention the possibility of a remote kill switch, because having that on an SLBM would render it useless by design, I hope the UK ruled that out when buying Trident)
No it doesn’t, only the rockets are from a shared pool the war heads are entirely British.

Would a remote killswitch for something aboard a submarine even be technically feasible? Radio waves don’t travel through water very well
The missiles have to travel through the air and even space eventually, after launch.
