How to Solve VVDI Key Tool Plus "EIS not synchronized" Error?

Problem:

We have x2 original keys. Both have same result on VVDI Key Tool Plus. Both keys remote central locking work.

And keys are seen by EIS when read eis key data.

Here is troubleshooting:

Step 1.Try to turn on and off the ignition to synchronize key

If there is no response from ignition. Have tried this many times. Key turns in EIS but no dash lights illuminate

Step 2.Use oem key or VVDI MB Remote?

Original keys that customer give us. No keys made. And they still operate central locking

Step 3.Make sure write new data in

if original keys are brand new, users still need to write data in;

if original keys are used, open key, desolder chip, erase data, and write new data.

Done! Hope this helps!
