What the pattern is telling you Record old preparations and patched timber before another alteration. Then test the current lock open and closed to separate internal mechanism resistance from closed-door alignment resistance. For hardware faults I would establish the current configuration before making another alteration. Record lock, latch, strike, bolts, access-control parts and previous machining. Test the mechanism open and closed where appropriate, because internal hardware resistance and closed-door…
