Hello I have an Audi80 B4 and I am just building a laptop in the trunk and a touchscreen in the center console at the front. Now my question: I would like to start my car by entering a code on the touchscreen or laptop. The laptop would have to somehow press a signal / switch so that the motor starts as if I was turning the key around in the ignition lock !. Is something like that to realize ? e.g. ignition lock remove the contact that the key when turning to the sta rten causes replace a usb cable to disconnect the connection to the ignition lock and deactivate the usb port or activate it from the laptop by entering the code when activating the usb port a contact is established in the ignition lock what causes the motor to start. after 5 sec then the usb port is deactivated again, the engine is started Oo Is that technically possible ? if yes how exactly ? or joa funts something ? or does I imagine that too easily ? have my car ignition lock oss technique not yet looked at exactly but will do in a few days when my parts are there for the carpc. MfG Fabian
