Replacing keys for an existing lock is difficult
Key bits, also known as blades, often require a specific cut to fit a lock. Determining this cut is complex. If key bit is not cut correctly, it will not engage lock mechanism.
Unfortunately knowing the manufacturer and model number of the lock does not help in locating a key to fit an antique lock.
Cutting the bit/blade, to turn the lock mechanism, often requires the skills of a locksmith.
Before choosing a key blank:
Determine lock-pin diameter This measurement is critical as key-barrel must slide over lock pin.
The key-bit must be sized correctly to move the lock-bolt .
Profile of key-bit varies between locks.
Some locks are easily turned with a simple un-notched blade
Other locks require a key bit with one notch to lock or unlock
Many locks require a key cut with 2 notches: one notch locks the lock the other notch unlocks the lock
Some locks, made with spring-loaded levers, also require 2 notches however they also must be different sizes. This type of key is difficult to reproduce
