Will This Fix My Problem?

Honest answer: here's exactly what this service fixes — and what it doesn't.

Fixes:

  • Need the DME ISN for an all-keys-lost BMW
  • Can't read MSD80 / MSV80 ISN over OBD, no key
  • Replaced the DME and now it won't sync to CAS
  • Locksmith needs ISN to make keys on a CAS4 car
  • FEM/BDC unlock needs the original DME ISN

Won't fix:

  • Mechanical key cutting (we supply ISN/data, not blades)
  • DME tuning, flashing, or repair of a dead ECU
  • Non-BMW ECUs
  • Comfort-access fob pairing on the car (done at the vehicle)

Frequently Asked

Still have a question? Text us — replies in minutes.

What is the ISN and why do you need the DME for it?
The ISN (Individual Serial Number) is the cryptographic pairing between the engine DME and the immobilizer (CAS/FEM). For all-keys-lost you must know the ISN to program a key, and on Continental DMEs it can't be read over OBD without ignition-on - so we read it on the bench.
Do I need to send the CAS too, or just the DME?
For a read-only ISN, just the DME. If you want us to align the ISN into the CAS or FEM/BDC so the car will start, send both.
What's long ISN vs. short ISN?
Long-ISN families (MSV80, MSD8x, MEVD17) carry a full-length ISN where matching the ISN alone is enough. Short-ISN cars additionally require an ECU-to-CAS sync - we flag which applies to your part.
Is this a locksmith wholesale service?
Yes - it's aimed at locksmiths and shops who handle the key cutting and on-car steps and just need the ISN pulled accurately on the bench.
Can you read ISN without de-lidding the ECU?
On most MSV/MSD/MEVD families we read the ISN on the bench without cracking the case. We'll advise if a specific stubborn variant needs more.
