I don't know what fantasy world you live in but the police don't ask you to remove your security mechanisms yourself. Your likely to catch a charge for destruction of evidence if you do that along with a bunch of other related charges
Considering that police can, with a warrant, forcibly place your thumb on your phone's fingerprint sensor to unlock it [1], "I don't know what fantasy world you live in" is unwarranted.
Removing the security mechanism in my comment is akin to opening the safe to enable the search or entering your PIN number on a phone to unlock it. I can't really see how otherwise removing a roadblock to enable law enforcement to perform their court approved mandate would lead to further charges for the act of helping them do so. Of course if you're referring to poison-pill mechanisms that upon removal destroy the data they wanted to search for then sure, more charges are coming.
That isn't how it works at all in the US. You'd be asked to provide the combination to the safe. Or compelled under a court order to divulge it under penalty of contempt of court.
If you're asked to directly interact with anything like that you're very likely being set up to bring additional charges against you. You can be compelled to provide passwords, combinations, etc. in a court. You can't be compelled to actually enter the safe combination
