When I bought my home it came with a french door to exit to the patio. I was told by the previous owner it can only be locked/unlocked from inside.
But after do notice there is a key hole, and you can put a real key in it (means it is not cosmetic), I just don't have the right key and I would want one.
Is it possible to have a locksmith and have him change the lock innards and get a working key and lock for this? I believe It is what is called a 5 bolt system.
Thanks in advance
