Is there a mercedes w164/x164/w251 eis repair shop in Phoenix I should use instead?
Most Phoenix shops don't keep the bench equipment for mercedes w164/x164/w251 eis repair — they'd forward the module to a specialist anyway, which adds a markup and a middleman. Going direct to us is usually faster and cheaper. Cross-country southwest — about 2 days each way.
Does Arizona vehicle inspection or emissions testing affect this service?
Arizona requires emissions testing in the Phoenix and Tucson metro areas; the rest of the state is exempt. Our service is bench module programming only — you remain responsible for your vehicle's compliance with all Arizona 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.
