A PCM or ECU replacement is only half the job—the module must be programmed to your VIN, immobilizer, and transmission settings, or the car won't start. Carhax clones or reprograms your PCM/ECU using data from your original unit, preserving all key and security sync.
This service is critical when sourcing a used ECU from a salvage yard or online marketplace. Carhax ensures the new unit is fully matched to your vehicle so you avoid expensive dealer programming fees and compatibility mistakes.
