I'm looking for help in finding out what kind of key I have exactly and whether or not I can find a place in the US that can duplicate it. My father purchased a new biometric lock for our house and it came with a key type that I have never seen before. The key is not cut into like a typical key but instead down the grooves on both sides has small drilled indents that are spaced differently and the drilled holes are different sizes and depths. I have no clue what to call this type of key. Nor did the local locksmith. I know that the manufacturer of the door knob is from Asia if that helps. I hope someone has the answer.

I am about to replace a 3 panel (4.0 ft) each ) - 12 ft total 18 year old sliding door in a coastal rental property I recently purchased. One panel opens but the rest are frozen . The rollers and weather stripping are shot (& obsolete ) and it is time for new door unit . I measured the heights at various spots and there is about 5/8" sag in the middle . There is vinyl siding on the outside and drywall on the inside. I would like to maintain the opening for a new door unit . I wondered if could cut the sagged portion then remove some drywall and install a steel plate (flitch plate) or plywood to eliminate future sagging ? I would appreciate any suggestions on how to address this situation . - Thanks
