Possibly you have another passive/RFID device in the same vehicle generating frequency at the same spectrum? As for range, I find antenna positioning is critical for it to work optimally. (I had to change it from underneath the dashboard to IP side cap area). OEM vehicle have the luxury of strategic placing multiple arrays of antennas through-out their car. So how you place your antenna will determine your range and effectiveness. Could you describe where did you place the antenna on the vehicle? How close is the antenna from the closest metal material? I can ask AK to give you some assistance to make it work better for you.
You fully described the inefficiencies of this system in your reply. Multiple arrays of antennas are going to be required to get OEM quality and that is what we are going after here. I too have tried various locations for the antenna and aside from having it sit on the very top of the dash, all other locations just don't give it the range it needs. You can get it so that it works ok from the drivers side but then you have to be standing right next to the vehicle to get it to work from the passenger side or the hatch area which at that point, it's just easier to pull out your keys and unlock the vehicle that way. Talk to your guys at AK and tell them they need to work on a multi antenna system and that will probably fix the issues people will see with your current system. FYI, you're going to want no less than 3 antennas (left, right, rear) and that is where I would go if you're going to make revisions. Also, tell your chinese supplier to loose the "Open Sesame" on the antenna because you guys and about a dozen others all have that on the antenna and I don't think that would instill a lot of customer trust in a product you say you've designed from the ground up. Just my 2 cents.
