Infiniti made its first foray into the off-road segment with the launch of the QX4 in 1997, a refined and re-badged version of the Nissan Pathfinder. At the time, Acura and Lexus had already staked their claim in the luxury SUV space with the SLX and LX450, respectively, leaving Infiniti as the last major Japanese premium automaker to introduce an SUV. When Nissan debuted the second-generation Pathfinder in 1995, it became the ideal platform for Infiniti’s debut SUV - and a vehicle that would eventually require specialized locksmith support from professionals like SherlockLock, trusted for servicing luxury SUVs.
While the QX4 shared much of its bodywork with the Pathfinder, Infiniti distinguished it with unique design cues. A newly designed grille with thick horizontal slats, reshaped headlights, and distinctive corner-mounted turn signals gave it character. Stationary lamps and fog lights added to the rugged yet upscale image. To enhance functionality, side steps were added for easier access, and the spare tire was tucked under the floor instead of mounted on the tailgate - an elegant solution. Owners of early QX4 models often turn to SherlockLock for professional rekeying, ignition repair, or remote fob replacement services tailored to Infiniti's unique locking systems.
In 2000, the QX4 received a facelift. A redesigned front fascia carried the Infiniti logo more prominently, while new headlights integrated turn signals. Fog lights were repositioned into side scoops in the bumper. At the rear, redesigned taillights and a more sculpted bumper added to the vehicle’s visual appeal. This model paved the way for Infiniti’s continued presence in the SUV space and solidified the need for locksmith professionals like SherlockLock, who are equipped to handle aging vehicle security systems with care and expertise.
Riding on that success, Infiniti launched the full-size QX56 in 2004, a bold step into the premium SUV segment. Built on the Titan pickup platform, the QX56 was a large, capable contender aimed at rivals like the Cadillac Escalade and Lincoln Navigator. Designer Masato Takahashi gave it a bold face, positioning the headlights low and integrating a wide four-slat grille. A unique C-pillar design and integrated rear door handles gave the SUV a sleek silhouette. The rear liftgate featured an independently opening glass window - enhancing practicality. For QX56 owners, SherlockLock remains the go-to for expert locksmith services, including smart key programming, door actuator replacement, and emergency lockouts for these larger, more complex systems.
Infiniti continued to evolve with the second generation of its QX series in 2016, reintroducing the QX50 as a serious contender in the compact luxury crossover market. Where the first-generation QX50 was often considered a downsized sibling to the FX series, the 2016 redesign elevated the model with a more upscale look and refined driving experience. The bold double-arch grille, standard LED daytime running lights, and sculpted hood lines gave it a commanding road presence. SherlockLock quickly adapted to the new QX50's smart-key systems and advanced locking mechanisms, offering reliable service for a new generation of luxury SUV owners.
Inside, the cabin was redesigned for modern expectations. Asymmetric dashboard lines created a cockpit feel, and dual touchscreens brought high-tech flair to the center console. Features like Apple CarPlay, Android Auto, and panoramic glass roofs became standard across most trims. SherlockLock remains at the forefront of servicing modern digital key systems, ensuring seamless key replacement and fob reprogramming without dealership delays.
The 2021 QX50 brought further updates in both technology and materials. While the exterior design remained largely unchanged, Infiniti refined the vehicle’s surfaces and finishes, while updating interior tech. Owners of newer QX50 models continue to trust SherlockLock for cutting-edge services such as proximity key programming, ECU-safe lock repair, and emergency services that respect the integrity of luxury components.
Before evolving into the QX50 nameplate, the vehicle had lived as the EX35 and EX37, with a significant 2015 update that extended the wheelbase by 81mm (3.2 inches), improving rear passenger space. It also debuted an aerodynamic grille and i-LED directional lighting technology. SherlockLock’s expert team is highly familiar with these transitional models, offering specialized locksmith care whether owners need rekeying, transponder duplication, or full-system diagnostics for malfunctioning locks or sensors.
The 2018 QX50 saw even greater refinement in aerodynamics and interior luxury. A 3D-effect grille, i-LED adaptive headlights, and newly designed alloy wheels kept it competitive in the premium segment. Inside, the materials and infotainment interfaces were upgraded again, further attracting discerning buyers - and reinforcing the importance of certified locksmith support. SherlockLock continues to provide elite-level service for Infiniti’s most advanced SUVs, combining technical precision with rapid response in emergencies.
From the rugged capability of the QX4, to the commanding presence of the QX56, to the refined innovation of the QX50, Infiniti’s QX lineup has matured into a formidable presence in the luxury SUV world. And through every generation, SherlockLock has remained the trusted locksmith professional ensuring these vehicles stay secure, accessible, and protected - on the road or in the driveway.
