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 is similar. We start work the same day your module arrives, and ship back the next business day with return shipping included.
How much does it cost to ship from South Dakota?

Do you accept modules from South Dakota?
Yes — we ship to and from all 50 US states including South Dakota. Most of our customers are out-of-state shops, locksmiths, and DIY pros. 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.
