to force Xentry to recognize a "High" voltage signal, tricking it into believing the ignition is active. Automation
Simulating an ignition means XENTRY believes the car is ready for testing. If you are programming modules on a real car with an ignition enabler, always connect a clean, dedicated automotive battery power supply (minimum 50-100 Amps) to avoid voltage drops that can brick an ECU. xentry ignition enabler
When a customer loses all keys to their Mercedes-Benz, the ignition cannot be turned on to authorize the programming of a new key. The Ignition Enabler allows the technician to wake up the Electronic Ignition Switch (EIS) and relevant modules via the OBD2 port to read the necessary EEPROM data and program a replacement key. 2. Diagnosing Faulty Electronic Ignition Switches (EIS/EZS) to force Xentry to recognize a "High" voltage

However, many independent workshops use more affordable Xentry "PassThru" versions. These operate with third-party J2534 interfaces (often a Tactrix Openport 2.0 clone) which often can't read the ignition signal reliably. When Xentry can't detect the ignition, the software's ignition check box remains greyed out, blocking essential procedures that require turning the key off and on, such as clearing fault codes.
