Used VVDI MB on a 2008 W906 Sprinter to program BE key, starts & runs. But can’t get remote to lock/unlock. Finally solved by changing the frequency TO 433MHZ. Read the details below.
Car model and year:
2008 W906 Sprinter
Benz key programmer to play with:
Symptom:
Have managed to program BE key, starts & runs. But can’t get remote to lock/unlock.
Have tried
Insert key into Ign
Remove key
Within 10 secs press & hold the lock button
Press the Unlock button 5 times
Press the boot release button
Release all buttons
Not working
How to do next?
After ignition on, remote work, maybe change frequency to 433MHZ with VVDI.
Finally! Solved!
Now works 433MHZ. Strange tho, the only other working key says frequency is ‘Control frequency by resistance control’ Is an older BE key
Good to know:
With XHORSE BE keys you can change frequency using VVDI MB while other BE usually have a resistor to control frequency. Since your sprinter has an IR EIS – you are not in the US and your frequency will be 434.
