Product Overview
The Lonsdor LT21-04 is a 4-button universal smart key PCB board built for 2025+ Toyota and Lexus proximity key systems. This listing highlights its changeable frequency design: the board supports 312.09/314.35 MHz and 433.58/434.42 MHz bands and ships with 312.09/314.35 MHz as default, so key service workshops can cover vehicles operating on either band with one stock-keeping unit.
Why Changeable Frequency Matters
Toyota and Lexus proximity keys use different frequency bands across markets and model years. A changeable-frequency PCB allows locksmiths to prepare one board type for multiple vehicles instead of holding separate part numbers, simplifying inventory and shortening customer waiting time.
Key Features
Technical Specifications
Before You Order
Confirm the original key PCB board number (0250) and the vehicle frequency band before programming. Smart keys and PCBs are non-returnable once programmed; send us the vehicle model and year so we can confirm suitability before shipment.
Quality and Shipping
Each board is inspected for button response, chip read/write and frequency output before shipment and packed in an anti-static bag with bubble wrap inside an export-grade carton. MOQ: 10 pieces. We keep regular stock for Lonsdor key products and dispatch within 3-7 working days.
