About Your 2026 Lexus RZ
Lexus is a Japan brand owned by Toyota Motor Corporation. Their key system uses Toyota Smart Key System / Immobilizer with Transponder, Smart Key. Lexus uses Toyota's proven immobilizer and smart key platform with premium refinements.
The 2026 Lexus RZ is a sedan. Most RZ keys of this generation use the Texas Crypto 128-bit transponder chip, remotes under FCC ID HYQ14FLB / HYQ14FBF, the TOY48 key blade — exactly the hardware we cut and program on-site. Key blanks for the RZ are stocked on the truck, so a typical spare-key visit anywhere in Duval County wraps up the same day, without a tow.
Your 2026 Lexus RZ is a modern-era vehicle and uses the latest revision of Lexus's key security platform. Programming requires advanced equipment but is fully aftermarket-supported on-site — no dealer trip needed in most cases.
Immobilizer (Toyota H/G Transponder): Toyota's H-chip and G-chip platforms have been refined over two decades. Programming is fast, well-documented, and supported by every modern aftermarket programmer.
