49 States See Declines, but California Remains a Hotspot as Thieves Exploit Keyless Entry and OBD Hacks
LOS ANGELES, Feb. 26, 2026 /PRNewswire/ — After years of increases, U.S. auto theft is finally trending downward — but the risk hasn’t disappeared. Mercury Insurance (NYSE/NYSE Texas MCY) reviewed auto theft statistics dating back to 2023 to track and share insights from those learnings.
According to the National Insurance Crime Bureau (NICB), 2025 saw a 23% decline in vehicle thefts compared to the same period in 2024, with 49 states reporting fewer incidents. That follows a 16.7% decrease in 2024 after thefts peaked in 2023, signaling a continued national slowdown. Still, theft levels remain elevated in key regions, particularly California, where more than 50% of statewide thefts occur in Southern California — especially Los Angeles County.
At the same time, criminals are shifting tactics.
Rather than traditional “smash and grab” break-ins, thieves are increasingly exploiting keyless entry systems, relay attacks and on-board diagnostic (OBD) port vulnerabilities to steal vehicles more quickly and quietly.
“While the number of auto thefts has been declining, incidents of crime still remain high, especially in California,” said Justin Yoshizawa, Product Management for Mercury Insurance. “It remains important that vehicle owners stay vigilant in protecting their investments.”

How Drivers Can Reduce Risk
Mercury Insurance encourages drivers to take proactive steps to protect their vehicles:
Use Steering Wheel Locks
- Highly visible deterrents remain effective, particularly for high-target models such as Kia and Hyundai vehicles.
Secure Key Fobs
- Store keyless entry fobs in signal-blocking pouches to prevent relay attacks.
Never Leave a Vehicle Running
- Even brief stops increase vulnerability if a vehicle is left unlocked or idling.
Consider Additional Anti-Theft Devices
- Kill switches, tracking devices such as Apple AirTags, and manufacturer-approved anti-theft technology may provide additional protection — and in some cases may qualify for insurance discounts.
“Mercury recommends that consumers stay up to date on the latest auto theft information,” Yoshizawa added. “Staying ahead of the curve may prevent you from becoming a victim yourself.”
