Electric strike does not activate	Remove the strike and check that the wires are connected properly Use a multimeter to test that the strike is receiving the proper voltage and amperage. If it is not, it may be necessary to use heavier gauge wires, or increase the output of the power supply Make sure the activation device (keypad or pushbutton switch) is working properly
Door does not open when the electric strike is activated	Check that the door latch is operating properly, and replace if necessary The position of the electric strike may need to be adjusted by moving it or adding washers or shims
