Factory new OEM Honda ECM/PCM - not a mile on it. You will need to have it programmed by a shop or dealer with ob2d programming software (Launch X431 we recommend). Your VIN# must be added to it along with linking your car key immobilizer or it will not work! This would be the case on any ECM you buy, used or new. The immobilizer and VIN# have to be added to the ECM or car will run for seconds and turn off. You do not need new keys etc - this is not true. Only fits what is listed below. No miles on it! Automatic Transmission Fits: 2016-2017 Accord 3.5L Sedan - California Emissions - without Pre-Crash System (Honda Sensing) The number on your old one MUST match one of the following: 38720-5G1-L01, 38720-5G1-L02 37820-5G1-L03 37820-5G1-L04 37820-5G1-L05 We will gladly ship worldwide.
