The LSID application is fourteen pages long and not exactly fun to fill out.
#WHAT IS MODULE EZS IN MERCEDES REGISTRATION#
With it you gain the authorization to provide security related services, such as immobilizer resets, security system initializations, and the creation and registration of secure electronic keys. As of now all DAS 4 component replacement is done by a certified technician in-house at the MB dealership.Ī key station is no longer required for DAS 4 vehicles because programming takes place in the EZS control module in the vehicle.Īll the other control modules of the drive authorization system are likewise taken into service via Xentry if the workshop has the appropriate authorization.Īs mentioned in the earlier blog post, to take advantage of this information and expand your business into the automotive security field, you need a Locksmith Identification (LSID) license.

The main control modules involved in DAS 4 verification are: If the drive authorization code is valid, the component is enabled independently. Provision of an online-based process to enable all the steps from teaching the keys to programming the DAS components to be performed completely and reliably using the diagnostic system (scan and pass-through tool).ĭAS 4 is a network of control modules, each of which calculates the drive authorization code independently.Comprehensive vehicle and parts documentation in the locking data management system.Greater ease of maintenance due to shorter waiting periods when programming keys and replacement components on the vehicle itself.Immobilizer with maximum security level meeting all legal requirements.The important goals of the new system are: The new SL-Class is the first MB model series to be equipped with the new drive authorization system version 4 (DAS 4). If the key fails validation, (even if, in the older systems, it is mechanically able to turn the ignition switch), the ECM prevents the engine from running. If a match is found, the engine control module (ECM) allows the engine to start and run, and DAS writes a new randomized rolling code to the key’s EEPROM.

These values are compared to known valid values stored in DAS.
#WHAT IS MODULE EZS IN MERCEDES SERIAL NUMBER#
Each time the key is used to start the vehicle, DAS reads both the fixed serial number and the rolling code. Each key for this system contains an EEPROM chip that stores a fixed serial number and a rolling code. Here we give you some specific information about MB security systems:Īll Mercedes-Benz vehicles manufactured in about the last ten years use a drive authorization system (DAS) to electronically validate the key(s) used to start the vehicle.
