Titan Lock & Key is based on West Fifth Avenue in Naperville. Our shop is open by appointment only, because our locksmiths bring the tools and hardware to your home, business or parking spot anywhere in the city.


Want new locks on your Naperville home? Our residential locksmith services start with lock changes and lock replacement for front doors, back doors, side entrances and garage entry doors. We install deadbolts, handlesets, knobs and levers, high-security locks and keypad smart locks, and we repair older locks near downtown that stick or won't latch. After a move, we can change every exterior lock or rekey hardware that's still in good shape, and cut duplicate keys on site.

Offices, medical clinics and shops along Ogden Avenue and Route 59, and the business parks near I-88, need locks that hold up to daily traffic. Our commercial locksmith services in Naperville include commercial lock installation, lock replacement and lock repair, panic bars and exit devices, and door closer repair. When an employee leaves, we change or rekey the affected locks, and we design master key systems so each person carries only the keys they need.

Lost the only key to your car? Our automotive locksmith services in Naperville include car key replacement, transponder key cutting, key fob programming, spare car keys and car lockout service for many makes and models. We make the new key where the vehicle is parked, whether that's your garage, a downtown parking deck or the lot at the Metra station, which often saves you a tow to the dealership.
