Ultion A1 Key Profile: What Locksmiths Need to Know About the New 1 Star PLUS Update

If you cut Ultion keys, there's a small but important change you need to know about.

Ultion has introduced a new key profile on its 1 Star PLUS cylinder range. The updated cylinders now use key codes beginning with A1 instead of the A0 profile found on earlier versions.

The change has a direct impact on key duplication. You can't cut the new A1 keys onto existing Ultion A0 or JMA TX-28 blanks, which means stock that previously covered the range won't work with these newer cylinders.

Key Blank Compatibility Guide

This guide explains how to identify the correct Ultion key blanks for different Ultion key variants. Proper identification ensures you always have the right blank for the job.

For older Ultion A0 keys, you can use original A0 blanks, JMA TX-28, or the new Ultion A1 blanks.

If a customer presents a newer Ultion A1 key, ensure you use an original A1 blank.

To avoid errors and ensure customer satisfaction, always verify the key variant before selecting a blank.

Referencing this guide regularly will help you maintain efficiency and accuracy in your key cutting services.
