Programmed (Cloned)

After purchase, ACS provides shipping instructions for sending your original ECM to our facility in Hialeah, Florida.

For supported modules, we transfer the required vehicle-specific data, immobilizer information, and coding to a compatible replacement ECM.

Once cloning is successfully completed, the replacement ECM is designed to operate with your existing vehicle security system and keys without additional dealer programming.

If the original ECM data cannot be read or transferred, ACS will contact you to discuss available alternatives.
