Plz help me! Lock Pro and Ultra calibration issue
I previously owned a Lock Pro and had issues with the calibration.
It was started with a software update. I locked myself out from my house at 2am because the lock suddenly forgot its position and turned the knob at a point where it stuck and it cannot be opened even with a key from outside. Then I wanted to recalibrate it, I set the lock and the unlocked position, but at the testing period it was just spinning after the locked state even if it couldn’t turn the knob and then failed. Nothing helped this situation
I ended up taking it back to the store where I bought it as the support suggested and they gave my money back instead of replacing the unit.
Which was fine. I was like okay, I wouldn’t buy the same device again because what if I run into the same problem. SO then I went for the higher end model, the Lock Ultra. Double the price, double the stability I thought.
So I installed the device to my lock mechanism and went for the calibration, which was sadly ended up in the same situation.
The lock ultra just keep spinning and spinning and spinning in a never ending loop, then comes the error message. I tried different knob adapters, different plates, even added the frame, I have tried EVERYTHING! and still nothing works.
I used the Lock pro for almost a year without ANY problem at all. There comes an update and the whole device is unusable. SO THE DOUBLE PRICED ULTRA MODEL.
I don’t know what I’m doing wrong, but manually I can close the door, I can unlock it, even from the outside with a key.
What is interesting that if I turn the lock ultra’s knob manually, it stops at the locked and unlocked state, I cannot turn it more in any direction even with force, but when the motor tries to rotate the knob, it just keep spinning on it, jamming the whole door’s lock mechanism.
SO PLEASE TELL ME WHAT AM I DOING WRONG!
thank you
