What should I do if the police want to search my car or my house?

All searches done without a search warrant are presumed to be unconstitutional. The law, however, permits police and law enforcement to conduct warrantless searches in certain situations, which the law in Pennsylvania and New Jersey, refer to as exigent circumstances. Exigent circumstances exist if there is a reasonable possibility that evidence will be lost or destroyed if police don’t search the property in question and confiscate the evidence. There’s a much higher level of scrutiny and expectation of privacy associated with a person’s home than a person’s car.
