Product Information

Keyless entry and keyless start systems are convenient, but far from essential features. While they do make entering and starting your car much easier, systems like this can come with a mountain of problems. Wang, S.; Chen, C.; Ma, J.

If you’re on a tight budget, your money may be better spent elsewhere – on features such as Blind Spot Monitoring, for example. Shoaib, M.; Bosch, S.; Incel, O.D.; Scholten, H.; Havinga, P.J.

"Keyless car crime up as gangs target vans". Auto Express . Retrieved 19 March 2016.This isn’t merely for convenience, though. The start/stop button is supposed to provide better protection against from car thieves. The car’s computer can only recognise the code from the driver’s specific key fob. Without the fob, the car can’t be stolen. It is important that the vehicle can't be started when the user and therefore the smart key is outside the vehicle. This is especially important at fueling stations where the user is very close to the vehicle. The internal LF field is allowed to overshoot by a maximum of 10cm to help minimise this risk. Maximum overshoot is usually found on the side windows where there is very little attenuation of the signal.

Radio waves are used in many different devices, and keyless remotes for cars are no exception.

First off, who leaves anything of value in their vehicle to begin with? If you’re leaving anything worth stealing in your car, you’re just getting what’s coming to you.
