The Oaklyn Fire Department (Station 18-3) is responsible for fire protection in the Borough of Oaklyn and until December 2007 was responsible for Haddon Township Fire District 3, which paid the Borough of Oaklyn for fire protection through tax money it collected from its residents. Fire District 3 covers the Bettlewood, Heather Glen, and Heather Woods sections of Haddon Township. This was a long-standing agreement that existed since 1905. From 1902 when the Oaklyn fire service was established until 1905, Oaklyn and the Bettlewood section were both in Haddon Twp. Subsequently, the Oaklyn Fire Company No. 1 of the Oaklyn section of Haddon Township provided fire protection to the whole area, as it was and still is a continuous land mass. When Oaklyn seceded from the Township in 1905 there was an agreement made between Oaklyn Borough and Haddon Township that Oaklyn would still protect the District 3 section since they were much closer and the fire apparatus was horse drawn at the time. This relationship continued for another 102 years until January 2008. Currently, Fire District 3 is protected by Westmont Fire Co. # 1 pursuant to three consecutive one-year agreements.
