Criminal groups have recently used a new method of stealing cars called a “relay attack,” in which they intercept the signal from a nearby electronic key fob and relay it to the vehicle.

The store where Chino works sells special key cases that neutralize relay attacks, preventing the electronic signals from leaking out from the key fob. Some products are so popular that they cannot keep them in stock, according to the store.

A popular theft-prevention item for motorcycles is a high-strength chain lock that cannot be easily cut. The chain can be locked around something like a sturdy pillar at a parking lot to prevent the bike from being stolen. Alarm systems that detect vibrations when a thief tries to steal a motorcycle and sound an alarm are also selling well, according to the store.
