Is there a mercedes w164/x164/w251 eis repair shop in Des Moines I should use instead?

Does Iowa vehicle inspection or emissions testing affect this service?
Iowa 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 Iowa 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.
