Will these keys work with F9 series guards or other brands?

While the F145-0999 is the primary standard for the White-Rodgers F29 series, some legacy models and specific cross-referenced units may share the same keyway profile. However, for guaranteed operation, it is recommended for F29 models.

Do I need to replace the entire lock if I lost my original key?

No, these are standard replacement keys designed to match the factory-installed locks on F29 units, allowing you to regain access without the labor of a full lock cylinder swap.

How can I tell if I have an F29 guard?

F29 guards are typically clear or solid plastic enclosures with a top or side lock. If your guard is a White-Rodgers branded plastic model designed for commercial use, this is the standard key for that series.
