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

No. The repair preserves all immobilizer linkages (EIS ↔ ECU ↔ ESL). Reinstall, insert your existing key, start the car.
What if my EIS is from a different chassis (W204, W211, W221)?
Those use different EIS architectures. See our Mercedes EIS Cloning (Pre-2014) service for W204/W211/W212/W221, or text us with your specific year/model.
