What is Car Key Programming?
Car key programming is the procedure of syncing a replacement key's internal transponder chip or electronic fob with the lorry's On-Board Diagnostics (OBD) system or Engine Control Unit (ECU). Without this synchronization, the car's immobilizer— a security gadget that avoids the engine from running unless the proper key is present— will not allow the lorry to start.
