Another way that smart keys help keep cars safe is by not sending the same frequency signal repeatedly again. If a smart car key replacement cost uk key sends a signal each time it unlocked or opened a trunk remotely, it could allow thieves to use hotwires to connect cars and eliminate them. Thankfully, this is not an issue because smart keys emit a unique encrypted signal every when a door is opened or the trunk is opened remotely.
Smart keys also prevent vehicles from being taken by thieves at fueling stations and other parking spaces.

Because smart key fobs emit an low-frequency signal which can be picked up by a device that could open the doors or pop the trunk. This is a tactic known as relay attack, and it’s been employed by thieves with the latest technology to take cars from drivers at fueling stations and even in parking garages.
Most smart key systems do come with a backup method to open and start the vehicle in the event of a dead battery.
