A call from a customer who has a Mercedes-Benz E350 W212 2012 without any working keys, the car is from US. I used Autel MaxiIM IM608 to program a new key successfully. I'd like to share the procedure in this article.
Now let’s start, this is a blank key.
Tap IMMO function, accept terms to access
Choose vehicle model - Smart Mode - All Key Lost - On Vehicle - Confirm information, then press "Yes"
Check the list and “BEGIN"
Insert the key on programmer, press "OK" - Do not unplug the USB cable, wait for a moment...
Having key password? "No" - Then press "OK" to get a new password - Check the list and "BEGIN"
Follow the prompts, press "OK"
- Connect the device, OBD cable and OBD connector on the wiring harness in sequence.
- Connect the IR key simulator(APB102/APB125) to the programmer.
Insert the IR key into EIS. If it is already inserted, remove and insert it again.
Wait for 10-30mins to get password, follow the prompts again and press "OK"
Insert blank key into IR keyhole, and press "OK"
All key lost completed!
Test smart key as instructions.
Jobs has done! It is working perfect. This is the second my Autel scanner.
It is good for diagnostics, too. To be updated next time...
