As already written my goal would be to replace the skreem completely, if only because of the delivery problem with the key fobs. I had read somewhere that Mercedes has problems to get suitable transponders. This electronic components are no longer produced because the transponders used by mercedes are from the 90s.
But if there is more interest from your side to have only a bypass for the immobilizer, I would be finished with the development and could offer this after several months of testing.
What do you want?
1. only bypass
2. skreem replacement
