Where to get the keys to Eclipse in Silent Hill?

Question

As written on the map that's inside the house by the doghouse. Don't answer with a guide, please.

Answer 1

The markers on the map indicate where you should be looking.

One is at the east end of Finney St:

in the trunk of the police car (the arrow on the map).

One is at the end of Ellroy St:

in a mailbox (the circle on the map).

One is between Finney and Matheson:

on the basketball court down the alley (this alleyway is the long line on the map).
