North Dakota has no statewide periodic vehicle safety or emissions inspection program. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all North Dakota and federal requirements.
Do I need to send a key?
YES — at least one working key. We bench-test the repaired EIS with your actual key to verify the immobilizer chain handshake works end-to-end. Without a key, we can't verify the repair.
What if no keys work at all?
You need the Key Replacement via EIS service instead ($150). We program a fresh key directly to the EIS in that case.
