Mechanical combination locks

Mechanical combination locks, or dial combination locks, are a time tested and reliable form of keyless security on safes, providing only a reputable and reliable brand, and model is used. Good quality combination locks will have parts engineered to ensure accuracy and in turn security, by making it difficult to manipulate the lock to open.

Combination dial safe locks are available in 3 wheel or 4 wheel configurations. The number of wheels directly relates to the amount of numbers in the code used to unlock the safe. A 3 wheel, or 3 number combination lock will have 1 million possible number combinations, with 800,000 useable combinations. A 4 wheel combination lock will have 100 million possible number combinations with 80 million useable combinations.
