Low-Budget Repairs includes several locked rooms and safes that require codes found by examining clues in each location. The guide matters because it helps players progress through the game’s repair properties and hidden areas without repeatedly searching for each clue.

At the home, the first door code is 1974, while the garden-gnome door uses 9217 or, in some saves, 9271. In the mansion, the secret-door code is 4916 and the safe code is taken from the car’s number plate, listed as 371830; the storage-space code is 438959. At the police station, the relevant room numbers are Chief Room 13, Waiting Room 02 and Phone Room 67.
