Master Key Plus

Display Option

Test Key for Fit

This unique feature allows the user to test a key to determine which locks it might work. Uses might include testing an old master key to find if it will work in the new locks, one might also wish to determine what change keys an incidental master key might work. The test feature pauses at each page on the display to allow the user the time necessary to see if any bittings will allow the key to work.

For example:

If you enter the highest level master as the test key, then all bittings will be "highlighted" as working combinations.... If you enter a submaster then only the key bittings under that submaster will be "highlighted."

As an exercise look at the first page of key bittings, and enter the first key's bottom pins as the test key, and see how many of the bittings will be "highlighted."
