Programming touches your car's security system, so we confirm ownership before any module is synced.

NASTF certified mobile programming
KeyModuleProgramm programs, reflashes and syncs ECU and ECM modules at your vehicle across Metro Atlanta, matching new or used units to your keys and immobilizer so the engine starts.
Call and a trained specialist reviews your module job.
(404) 737-0061ECU and ECM are often used for the same part: the computer that controls your engine. Strictly, ECM means the engine module, while ECU can mean any electronic control unit in the car.
On a Nissan or Infiniti, the ECM talks to the BCM and the NATS immobilizer. That is why a replaced engine module will not start the car until it is synced to your keys. We program the ECM, TCM and BCM, so you get one technician for the whole chain.

What we offer
We install, program, reflash and sync replacement or used ECMs to your keys and immobilizer, then confirm the engine starts and runs correctly. A used module only works once it is matched to your car, and we handle that.
Call and describe your module, new or used, so the technician plans the sync.
(404) 737-0061We program ECU and ECM modules on Nissan and Infiniti vehicles from 2000 onward, the two makes we are certified to work on.

(404) 737-0061Yes. We write your car's VIN to the used module, then run NATS synchronization so it accepts your keys and immobilizer. When it helps, we bench clone data from your original module with VVDI Prog EEPROM reading. Tell us the part number and source before the visit.
Yes. We diagnose Key System Error with CONSULT, then sync the new module to the NATS immobilizer and re-register your keys with CONSULT III Plus. This is a common result of a module replacement that was never matched to the car.
Yes. Your 2019 falls in the 2018 and newer range that uses the 20-digit rolling PIN, and we read that code on site. With it, we synchronize NATS to the ECM so the engine accepts your keys, all at your vehicle instead of at a dealer.
In most cases, yes. The technician brings dealer-level software and the programming equipment to your vehicle, same day across Metro Atlanta. Service runs Mon to Sun 9:00 am to 8:00 pm, so a no-start does not have to mean a tow.
Yes. We offer All Keys Lost service along with ECM programming. We sync the module to the immobilizer and program new keys, including Intelligent Keys, with CONSULT III Plus, Autel IM608 Pro II or Xhorse VVDI. Have your VIN, photo ID and title or registration ready.
No. We program Nissan and Infiniti vehicles from 2000 onward. Give us the exact year and model and the technician confirms which tools and procedure fit your car before the visit.
