Originally developed as part of Mazda’s ambitious luxury expansion under the unreleased Amati brand, the Mazda Millenia was never just another sedan - it was a precision-engineered luxury vehicle intended to compete with high-end European marques. When financial constraints halted the launch of Amati, Mazda pivoted, releasing the vehicle globally under various names: Xedos 9 in Europe, Eunos 800 in Japan, and finally, as the Millenia in the U.S. market in 1995, where it succeeded the 929 as Mazda’s flagship.
From the outset, the Millenia stood apart, not only in terms of its quiet elegance but also through the intricate design standards rarely seen in Mazda’s mainstream lineup. Every element - from its tight panel gaps and thicker paint coating to the premium interior materials - reflected the upscale audience Mazda originally envisioned. These design choices would later make the Millenia a favorite among owners who appreciated both refinement and individuality.
Today, owners of classic models like the Millenia often require specialized services when it comes to maintaining their vehicles - especially for lock and ignition systems that are no longer common in modern cars. That’s where SherlockLock comes in. Our technicians are fully trained to work with legacy key systems, offering solutions like ignition rekeying, door lock repair, and lost key replacement - even for models equipped with sophisticated, hard-to-source mechanisms like those in the Millenia.
What truly distinguished the Millenia from its competitors - and from other Mazdas - was its engineering. It debuted on a unique platform and was the only production car of its time to utilize a Miller-cycle engine, an innovation designed for fuel-efficient performance without sacrificing power. The Millenia S trim featured this turbocharged, high-efficiency V6 engine, giving drivers both refinement and sporty responsiveness.
Meanwhile, SherlockLock provides modern solutions for this rare vehicle's unique needs. Whether you’re restoring a Millenia S or driving one daily, we handle transponder key duplication, vintage remote programming, and trunk lock replacements with care and accuracy befitting this once-luxury car.
In Japan, some versions came equipped with yaw-sensitive 4-wheel steering, enhancing cornering stability to rival sports cars like the BMW 850i or Nissan 300ZX in dynamic tests. In fact, Mazda claimed that the Millenia’s handling could meet or exceed the famous elk test - proving that this was no ordinary luxury sedan.
The Millenia underwent its first major facelift in 1997, coinciding with the end of the Eunos brand. While a few cost-saving measures were introduced - such as swapping the aluminum hood for a steel one - the sedan retained its sophisticated core. A second refresh followed in the 2000–2003 model years, giving the Millenia updated aesthetics without losing its original identity.
Notably, the Millenia had no direct predecessor or successor in Mazda’s lineup. It was a stand-alone experiment in refined engineering, and it continues to hold a special place among enthusiasts and collectors alike.
For those maintaining their Millenia into the 2020s, SherlockLock offers dedicated support for high-security laser-cut keys, trunk and glove box lock services, and emergency vehicle access for models where standard locksmiths may struggle. With unmatched reliability and a commitment to detail, SherlockLock is proud to support Mazda Millenia owners across Massachusetts and beyond - helping preserve a forgotten luxury legacy with modern precision.
