Local Service

Locksmith Help for Long Island Homes

Long Island houses tend to have several entrances: front, side and garage doors, basement doors, patio sliders, sheds and gates, and on the South Shore often a dock gate too. We put them on one key where the hardware allows, add high-security deadbolts and install smart locks so family and guests can use codes instead of keys.

In co-ops and condos in Great Neck, Mineola, Long Beach and North Hills, we follow building rules on cylinders and keys. If you rent, check your lease before changing locks.
