Do you accept mercedes w164/x164/w251 eis repair modules from South Carolina?
Yes — we receive modules from Charleston, Columbia, Greenville, North Charleston and the rest of South Carolina regularly. With about 4.2 million registered vehicles statewide, trucks, SUVs & imports are the bulk of what we see from South Carolina.
Is there a mercedes w164/x164/w251 eis repair shop in Charleston I should use instead?
Most Charleston 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-region southeast — about 2-3 days each way.
Does South Carolina vehicle inspection or emissions testing affect this service?
South Carolina 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 South Carolina and federal requirements.
How is this different from your EIS Cloning service?
Cloning copies your EIS data onto a donor unit (you keep using the donor; original is set aside). Repair fixes the failed components INSIDE your existing EIS so you keep the original. Repair is cheaper, no donor needed, and preserves the factory VIN binding.
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.
