The US doesn’t “have the keys” to UK nukes (ie the UK doesn’t keep US approval to fire them), but they are maintained and built by the US (I’m sure if they had to, they could figure it out themselves).

Will a country with 1000 nukes invade a country that has “only” 5?
The UK and France have more than 500 nukes.
