- Battery Drain: Programming can take substantial power; specialists use a battery maintainer to prevent the car's system from crashing mid-program.
- Damaged ECU Data: Using cheap, unproven programming tools discovered online can permanently damage the vehicle's computer, causing repair work costing thousands of dollars.
Preventive Measures for the Future
To avoid the stress of an emergency situation lockout, vehicle owners are motivated to follow these proactive steps:
