As any good Philadelphia locksmith will tell you, there is a plague in the city which effects the security of a majority of households. This plague is that of old dated locks which are not only prone to malfunction, but to completely breaking. You can find many dated and weak locks like this on Philadelphia’s many of Philadelphia’s older row homes. Due to the chance of breaking and malfunction, it is recommended that you have older locks completely replaced. The only issue with having locks like this replaced is that you must make sure that a locksmith company is going to be able to replace a mortise lock, like the one pictured below. This will allow you to keep your existing door which, in older homes where these locks tend to be located, is normally a very nice and solid wooden door.

An old mortise lock like this is common to see on an older Philadelphia home.
