Lonsdor Land Rover Jaguar JLR 2015-2018 Smart Key PCB 315MHz

It’s the internal electronic board used in the smart remote (key fob) for remote functions like lock, unlock, trunk, panic, and keyless start.

Frequency is 315 MHz, matching many North American & some global JLR vehicles.

Typically you’ll need a compatible key programmer (like the Lonsdor K518 series or similar) to add or program the new PCB to the car.
