The new Mercedes S Class W221 and the new C Class (also alot of the newer Mercedes) have a secured micro known as the HAVANNA made by NEC. At this moment it is not possible to read this chip. Development of this module is ongoing.

At this moment the only solution is to fit a can blocker , which we can supply and fit.

We now have a 100% solution that will rectify all memories including the EZS also known as the key module. Please contact us for price or to arrange an appointment.

As you have heard about this new micro, here are a few images for your information :

Keep watching this space, we hope to have an update very soon .
