Yes.
It's a 434 remote, and it's a Euro MB, so should be OK.

What type of keys you are trying to program ?
When you put key in eis is the led turn on ?
If yes try to take out and reinsert 5 times
And if you are testing eis on bench need elv to be conected or elv emulator
If orig key and you renew the key sometimes  times the nec  get damage

My personel opinion i find vvdi prog safer than R270

If be key it should work straight away after a activating key

I use VVDI yelow PCB key.
Car already starts, just remote (lock/unlock) don't work.
On bench i test with Goldcar MB test platform with built in ELV emulator.
Could be the flash the problem why lock/unlock don't work?

Found rear Sam fuse 8 blow. 
Exchanged it, but keep blowing fuse.
Then disconnect alarm horn and don't blow fuse anymore and remote work fine now.
