EVO One RFK441 2010 Hyundai Tuscon, regular key. Remotes only work every so often.

Everything programmed correctly as per the guide, no issues there. The remotes, even though they are one way, seem like they are acting as a 2 way remote. Both remotes programmed correctly on initial setup. Sometimes one of the remotes will work correctly to lock and unlock the doors, the LED on the remote giving one initial flash, then 5 quick flashes and the function works on the car. Other times, you push the lock or unlock, and all you get is a single flash, and no response from the car. It is very random, sometimes it's one remote, sometimes it's the other. Sometimes when I pick up one of the remotes, I see the LED give a single flash, but I haven't pushed a button.

After a period of time, they both seem to start working properly to lock and unlock the car.  Once that happens, you can remote start it once. Sometimes you can shut it down with the remote, sometimes you cannot. After that, neither one of the remotes will work at all. They go back to a single LED flash when the lock or unlock is pressed. Eventually one of them will start to work, then the other.........This has to be the strangest behavior I've seen from an RF remote.

Hello,

I would first start by checking the batteries of the remotes, if they are weak they may act strangely. If the batteries are fine, I would suggest trying a new remote kit (remotes, cable and antenna). The remotes should not be blinking at random when simply picking them up.

Best regards.

I checked the remote batteries, and even went as far as testing them as I was pushing the remote buttons. One curious thing I did find was that, out of the case, they seem to function just fine. I was unable to perform a lengthy test due to time constraints, but they seemed to operate as expected when not in the case. I may have to go back to the supplier and see if this is something they have been experiencing with these units.
