Lonsdor LT30-03 2022-2024 Toyota 4A-AA / 4A-BA 5 Buttons Universal

Lonsdor LT30-03 2022-2024 Toyota 4A-AA / 4A-BA 5 Buttons Universal Smart Remote Key PCB

The Lonsdor LT30-03 is a universal smart remote key PCB built for 2022-2024 Toyota vehicles using 4A-AA and 4A-BA smart systems. Supplied as a bare circuit board rather than a complete key, it lets locksmiths reuse an existing Toyota smart key shell and simply swap in a fresh, programmable board — a fast and cost-effective solution for lost key and spare key jobs.

The Lonsdor K518 programmer family generates and writes the board, loading the correct Toyota smart key data onto the PCB before it is registered to the vehicle. One universal board replaces the need to stock multiple individual Toyota smart key part numbers.

Programming Notes

This PCB must be generated with a compatible Lonsdor key programmer. The tool writes the required Toyota 4A smart key type onto the board, after which the key is added to the vehicle using the standard immobiliser procedure for that model and year. Always verify the vehicle's smart system (4A-AA or 4A-BA) and frequency in your Lonsdor tool before generating.
