Modern vehicles rely on a network of control modules—ECU, TCM, BCM, ABS, and more. When one fails, it can leave your vehicle immobile or unsafe. Carhax uses dealer-grade diagnostic and programming tools to replace, reprogram, or clone modules without losing your immobilizer sync.
Whether your vehicle needs a BCM swap after a break-in, an ECU replacement after water damage, or a cloned module to avoid dealer markup, Carhax handles it on-site with no tow required. We cover most domestic, import, and luxury makes and models.
