It should be law that all companies supplying a vehicle for sale or have provided a vehicle with a keyless entry system, that they must include with new sales and replace old keys with a key fitted with an isolating button or switch that can be pressed / switched by the user on the key that will disable the feature of keyless entry and ignition of a vehicle.

This one launched will immediately stop relay car theft as the key device will stop broadcasting the frequency once the switch or button is activated. 

The consumer believes that the launch of keyless devices has been rolled out loosely with very little security measures considered and this is a reasonable request from the consumer that they make the this adjustment free of charge for any previously sold or future sold vehicles with keyless entry.
