Lexus smart keys look nearly identical across the lineup: the same silhouette covers an ES sedan and a GX off-roader. The difference is the board inside. Lexus remotes use the same board families as Toyota, a fob only programs to vehicles built for its board, and the button layout is a second filter on top: a trunk-button fob on a hatch vehicle leaves that button dead even after it programs.
Running the VIN through EZ-Codes returns the exact OEM part number for that specific Lexus, which identifies both the board and the button configuration. That takes the guesswork, and the returns, out of replacing a lost or damaged remote.

Lexus uses the same board generations as Toyota: early 0140 boards, the 3370 "E" board (both with an FCC ID ending in AAB despite not being cross-compatible), and newer boards such as 5290, 0020 and 2110. Boards do not work on each other, with only a few exceptions, so the board number is the first thing to get right.
A Lexus remote with the same board type can often be programmed to a Toyota, and the reverse is also true. The catch is functions and blades: trunk and hatch buttons aren't interchangeable, and emergency keys come single-sided or double-sided. The part number tells you which combination the car actually takes.
Virtually every modern Lexus is push-button start with a proximity smart key, most in the 89904 part family specified per exact vehicle. Card-style keys exist for some models as a slim secondary remote.
Because the shells are so uniform, Lexus is where photo-matching fails most often. The part number is the only visible difference that reflects the internal one: board, buttons and blade.
Covered models include: RX, NX, ES, IS, GX, LX, UX, TX and the rest of the Lexus lineup.
Enter the 17-character VIN in the lookup on this page. The exact OEM part number for that vehicle comes back in seconds, identifying the board type and the button configuration.
Often yes, if the board type matches. Only the part number tells you whether the buttons and the emergency blade will also match: a Toyota trunk-button fob on a Lexus hatch model will program but leave the hatch button dead, and single-sided and double-sided emergency keys are not the same blade.
Yes. Toyota and Lexus coverage go together on EZ-Codes, and one VIN search works for both brands.
