Good evening.
I was hoping to gain some advice.
I have recently had to recalibrate the lock a couple of times over the last few weeks. However on the last calibration the lock jammed. I removed it and checked the barrel and that is free and working fine. I reinstalled the U200 and have found that although it is operating, it doesnt feel as free as it used to and the gearing inside feels/sounds like it is grinding slightly.
Any advice or help would be great?
