Replacing Keys on Furniture Locks

Fitting Furniture Keys

Replacing keys for an existing lock is difficult

• Knowing the manufacturer and model number of the lock unfortunately does not help in locating a replacement key.  The majority of historic lock companies are no longer in business.

• Replacing keys on existing locks is very difficult.

  • The lock mechanisms are often quite complex requiring a specific cut pattern in the key bit.
  • These cut-patterns are rarely interchangeable. 
  • A locksmith is often required to cut the exact pattern in the key for it to turn the lock mechanism.
  .

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 .

Key-bit Patterns vary according to individual locks. 

• Some locks are easily turned with a simple un-notched blade
• Other locks require a key bit cut pattern to have one notch to lock or unlock
• Many locks require a key bit cut pattern to have 2 notches: one notch locks the lock the other notch unlocks the lock
• Locks made with spring-loaded levers require a  very specific key bit cut pattern. The cut pattern is often complex. This type of key is typically very difficult to reproduce.
• We do-not know of or have a guide for how to determine the key bit pattern. A locksmith, who is familiar with older locks, is our best recommendation.
