South Dakota FAQ
Common questions from customers shipping from South Dakota.
How long does shipping take from South Dakota to your Arlington TX workshop?
USPS Priority Mail from Sioux Falls, SD reaches our Arlington workshop in about 2-3 business days. 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 South Dakota?
USPS Priority Mail flat-rate from South Dakota to Arlington TX runs about $12. Customer pays shipping to us; return shipping back to South Dakota is included in the $150 service price.
Do you accept modules from South Dakota?
Yes — we ship to and from all 50 US states including South Dakota. Our Arlington TX workshop receives modules from Sioux Falls and the rest of South Dakota every week.
Is there a mercedes key replacement via eis shop in Sioux Falls I should use instead?
Most local Sioux Falls shops don't offer mercedes key replacement via eis 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 Sioux Falls: typically 5-7 days.
Do I need to send an original key?
No. We program a brand new key from scratch using only the EIS — no original key required. This is the cheapest path for all-keys-lost on pre-2014 Mercedes.
What's the difference between this and EIS cloning?
Cloning ($250) copies your old EIS data to a donor EIS so existing keys keep working. This service ($150) programs a fresh new key directly on whatever EIS you ship us — original or replacement.
Will my old keys still work?
If we program a new key into your existing EIS, yes — any existing working keys keep working. If you ship a replacement EIS, only the new key we program will work in it.
