1. Locate the starter solenoid. The starter solenoid is a small, cylindrical device that is located on the front of the engine, near the battery. It is typically black or silver in color, and it has two wires connected to it.
2. Use a screwdriver to bypass the starter solenoid. To do this, simply insert the screwdriver into the two terminals on the starter solenoid, and turn it clockwise. This will cause the starter motor to engage, and the engine will start.
3. Once the engine is running, remove the screwdriver from the starter solenoid. The engine will continue to run without the screwdriver in place.
Here are some additional tips for starting a 1971 Volkswagen Beetle without a key:
* If the engine does not start when you turn the screwdriver clockwise, try turning it counterclockwise.
* If the engine still does not start, check to make sure that the battery is properly connected.
* If the battery is properly connected, you may need to replace the starter solenoid.
* If you are unsure of how to perform any of these steps, it is best to consult with a qualified mechanic.
