Unfortunately almost every new car on sale today has either keyless entry or keyless entry and start. For example, lower-specification examples of the Vauxhall Corsa do not have keyless entry, but they do have keyless start, so it depends which technology you are trying to avoid.

There is a small risk of theft for vehicles with keyless entry and/or keyless start, but the means of protection from this threat is the same for both - a good quality Faraday pouch. If your car has keyless start but not keyless entry then a thief will still have to gain access to your car to start it, but similarly if it has keyless entry but not keyless start there is still the threat of theft from the vehicle itself.

The latest Mercedes-Benz models fitted with Keyless Go have the option to turn off the remote function when not required, which prevents the key signal from being grabbed. Additionally some Land Rover models are fitted with ultra wide-band radio technology which prevents thieves from capturing the signal.
