Another way that smart keys help keep cars safer is by not sending the same frequency signal over and over again. If a fob sent the same signal each time it locked doors or remotely opened the trunk, it could let thieves who are adept at technology to use hotwires to make them disappear. smart car key fob keys emit a distinct signal every time a trunk or door is opened remotely.

Smart keys also help in preventing theft of cars at gas stations and other parking spots. This is because they send a low-frequency signal that can be picked up by the smart key in close proximity, but not by other people or objects outside of the vehicle. The signal can only be identified within 10 cm of the smart key, which means it is virtually impossible for anyone to steal your car just by picking up a signal from a nearby fob.

Convenience

This is a technique known as relay, and it's been used by tech-savvy criminals to steal cars at fueling stations as well as parking spaces.

However, all smart key systems include an alternative method of opening and re-starting the vehicle in the event that the battery fails. The driver is required to place the dead key fob in a slot or hold it close to a specific space in the cockpit to activate the emergency starting system.
