My Remote works just brilliantly from a very long distance.
I have only recently bought a car that has this technology, and I tend to forget to lock it.
Last year we were in Tassie, and parked the car and walked to the markets, it was then i said to Alice "I don't know if i locked the car" better go back and check.
We were a long way from the car, at least 300 meters, but i could see it, so I said to myself, "maybe it will work from here".
Yep it did, the lights flashed and then i pressed it again, and again, it has a huge range.
Now having said that I bought Alice a new car which is a Kio Rio, we use it to just run around town in, and unless you are less than 10 meters away it will not work at all, now figure that.
