There is no need to install a toggle switch on a gasoline golf cart to prevent theft, as the keys are not interchangeable. It is possible for someone to hot-wire the cart, but this would require bypassing the ignition switch entirely, not just installing a toggle switch.
If you are concerned about theft, there are a few things you can do to deter thieves, such as:
- Park the cart in a well-lit area
- Use a steering wheel lock or chain
- Install a GPS tracking device
- Insure the cart
