Oklahoma FAQ

Common questions from customers shipping from Oklahoma.

How long does shipping take from Oklahoma to your Arlington TX workshop?
USPS Priority Mail from Oklahoma City, OK reaches our Arlington workshop in about 1 business day. UPS Ground similar. We start work the same day your module arrives, and ship back next business day with return shipping included.
How much does it cost to ship from Oklahoma?
USPS Priority Mail flat-rate from Oklahoma to Arlington TX runs about $9. Customer pays shipping to us; return shipping back to Oklahoma is included in the $399 service price.
Do you accept modules from Oklahoma?
Yes — we ship to and from all 50 US states including Oklahoma. Our Arlington TX workshop receives modules from Oklahoma City and the rest of Oklahoma every week.
Is there a mercedes w164/x164/w251 eis repair shop in Oklahoma City I should use instead?
Most local Oklahoma City shops don't offer mercedes w164/x164/w251 eis repair as a bench service — they'd send the part to someone like us anyway. Going direct saves the markup and shortens the timeline. Total round-trip from Oklahoma City: typically 5-7 days.
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.
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.
