keyless thievery - fixed?

[DrJon]

Good evening all - the current edition of Which says that MB have instituted a protective device that will allow you to "turn off the key" which is effective even in pre-2018 models. Does anyone know what they are referring to?
thanks!

On older keyless cars, you press the lock button twice and the key stops responding to keyless requests.

On newer keyless system, the keys have a motion switch in them, which turns them off after a small period of non movement.

On older keyless models, blip the remote lock button twice rapidly.

You will know it has worked when the locking horn bleeps twice.

Well, that was easy! Many thanks

I was reading the other day that the new iphone software will enable certain cars to be started with the iphone.
I can imagine iphone hackers and car thieves are comping at the bit.
