Well if you live in a normal country with self-incrimination protections and not a shithole like the UK then you don't have to surrender the keys, what is more, it is advised for you to not speak or revea any data when asked by law enforcement.
The end.
The UK literally broke the most important self-incrimination protection - never enter the UK without plausible deniability encryption (for example veracypt containers) especially if you own any cryptocurrencies
