These source-listed applications cover different years, products, and equipment alternatives. They are candidates for identification, not a single specification for every GS. Confirm the VIN, market, trim, build date, installed equipment, and key label before ordering.
Years use the US catalog selection window. Source ranges can include other markets; only their overlap with selectable years is grouped below. Missing years or references require individual identification and do not establish whether a vehicle has an immobilizer.

Separate entries are alternatives or overlapping source applications; do not combine them into one key. A part number, FCC ID, or frequency alone does not confirm compatibility, local stock, or service availability.
Select the exact model year to see its service details and referenced applications. The model name or year alone does not establish the installed immobilizer, key type, or programming method. Confirm the VIN, market, trim, and any replaced components against the source references and the vehicle.
Spare-key and all-keys-lost service: 2000–2020.
Have your VIN, trim, and any existing keys available. Describe how you start the vehicle: turn a key, press a button, or use both. Tell us whether any working keys remain and whether you need a spare, a replacement remote, or help after losing every key. Include a photo of the original key and its label when available.
For supported Lexus GS jobs, confirm your location, parts availability, and appointment time before booking. Our business hours are 7 AM – 10 PM, every day. Travel and time-based charges are disclosed before dispatch, and you approve the complete price before work begins.
Have the VIN, model year, trim, ZIP code, and any existing key available. Tell us how you start the vehicle and whether any key still starts it. A photo of the key and its label helps identify the replacement.
Spare-key and all-keys-lost service: 2000–2020. These are model-year service groups; confirm your exact vehicle before booking.
Your confirmed quote specifies the key or remote, cutting, and any programming needed for your configuration. A mechanical key and an electronic key do not require the same work.
We offer mobile appointments for supported jobs. Confirm your exact vehicle and whether a working key remains before booking or arranging transport.
No. Match the exact model year, market, installed equipment, and part or remote details. A similar-looking key or matching radio frequency does not establish compatibility. We confirm the hardware when quoting.
