A major vehicle security flaw linked to nearly half of Victoria’s car thefts has reportedly been addressed in newer Holden and Toyota models, offering hope in the fight against rising vehicle crime.

Victoria Police say criminals have increasingly used electronic key-cloning and diagnostic devices to steal push-button-start vehicles without needing the owner’s keys.

Recent data shows that around 30 to 40 per cent of car thefts in the state have involved these high-tech methods.

Holden, Toyota and Subaru vehicles equipped with push-start technology have been among the most targeted models, prompting manufacturers to work on improved security measures.

Police believe updates introduced in newer vehicles have helped close a vulnerability that thieves had been exploiting for years.

Despite signs of progress, Victoria continues to face a significant car theft problem, with vehicle theft rates remaining among the highest in Australia.

Insurance data shows theft-related claims and costs have surged in recent years, making vehicle crime a growing concern for motorists and authorities alike.

Police are urging drivers to remain vigilant by parking in secure locations, using steering-wheel locks and installing additional anti-theft protections where possible.

Authorities say continued cooperation between car manufacturers and law enforcement will be critical in reducing thefts and protecting vehicle owners.
