Lonsdor LT20-07NJ Universal Smart Remote PCB 8A for Lexus 4 Buttons 312.09/314.35 – 433.58/434.42

These are replacement smart remote PCBs — the internal circuit board of a key fob that transmits lock/unlock/trunk/panic signals and communicates with your car’s smart key system. They are typically used by locksmiths or experienced technicians to:

• generate/program a new smart key,

• replace a damaged key PCB,

• switch frequency between supported bands, and

• convert between key types (e.g., 8A and 4D) with the right programmer tool (like a Lonsdor K518 or KH100+ device).
