What is the range of a remote entry system for a car?

I just had a system installed remote entry in my 2001 Caravan and will not work unless I'm about four feet from the driver's door. When I try to open the tailgate, I must go near the front of the car before to unlock the doors. If I have to get that close, you might as well go another few feet and put the key in the lock. I called the installer and was told that the systems Remote access is not supposed to work remotely, as for alarm systems or remote start systems. This sounds like bull to me. It?

It is true that the range not considered as important with keyless entry systems, as systems of remote start. With remote start, wants to be able to start your car during your stay in his nice warm house. With a keyless entry system, it is enough that you can unlock in the moment you walk up to it. However, most after the keyless entry systems market have a better range of what you're describing. The only time I've seen series as bad as it was in a factory system that uses a Infrared remote control (like a TV remote controller). You can search the antenna, there would not be a separate piece of the antenna made to stick to the top windshield (in which case the interval should be definitely better than what I described) or, more frequently, which looks like a piece of wire that extends from the "brain" of the keyless entry unit. You should be able to see the "brain" of looking up at your board, you will probably find be strapped to the factory wiring or structure … There is no reason that is hidden. The antenna should not be coiled or stacked, but should be extended to full length, not pinched or shorted, and preferably away from metal (obviously, it is impossible to completely clear of metal under the dash, but it should be sealed with tape adhesive to a metal key throughout its length, for example. Do you know the make and model of your keyless entry system?
