I wonder if anyone can help, I have keyless entry on my 197. Ive owned the car for about a week now and for the first 4 days the car would open when I walked up to it (Im sure). Now I have to try and open the door before it unlocks, I think there is a sensor on the handle I noticed erlier. So I now have to hover my hand round the handle for it to open. Am I imagining things or do they not open when you walk within a few feet? Unless it was passengers placing their hand arround the passenger side handle? I dont know weather I have changed anything by holding/pressing a button combo to change this. Any help appreciated. Thanks, Mike.
