Lock and Keystone Policy

Error-Free Guarantee

At Lock and Keystone, learning activities should be driven by rigorous content knowledge, not accidental formatting glitches, broken links, or typographical mistakes. We hold our digital lessons and teacher access resources to a high standard for classroom use.

Even careful scholars can occasionally overlook a detail. If you or your students find a substantive error in any purchased Lock and Keystone resource, we want to make it right.

"To find the exit, you have to find the truth. And if our truth has a typo, we owe you a rewrite. Hoo-hoo!"

What Qualifies as a Substantive Error?

We distinguish between minor cosmetic issues and structural breakages that affect classroom flow. A substantive error includes:

• Historical, literary, scientific, or curriculum inaccuracies: a misstated core lesson fact, date, source detail, or curriculum benchmark.
• Broken escape logic: a lesson PIN, code word, or printed access detail that does not match the validation logic of the companion digital lesson.
• Flawed answer keys: incorrect teacher verification data for a node, activity, lock, or final code.
• App-blocking glitches: a technical issue that prevents progression even when a student enters the correct text-verified answer.

Found a Flaw, Get a Freebie

If you are the first to report a verified, reproducible substantive error in a resource you purchased, we will provide:

1. Immediate correction: we will patch the digital lesson or update the downloadable PDF payload as quickly as possible, usually within 48 business hours. You will receive instructions for downloading the corrected version.
2. Free resource credit: as a thank-you for helping protect academic accuracy, we will provide a voucher for 100% off one single digital escape room or lesson access resource from our storefront library.

How to Report an Issue

To claim a replacement or free resource credit, please have your invoice or purchase email handy and include the following details:

• Your name and shop username: Etsy, Teachers Pay Teachers, or storefront account name.
• Resource title and version: for example, Grade 3, Unit 4, Lesson 13: The Colosseum.
• Location of the mistake: teacher access PDF, answer key, lesson PIN, digital app screen, or specific node.
• Description of the breakdown: what went wrong, what answer was expected, or what piece of evidence contradicts the target answer.

Terms of Use Reminder

Reporting an error does not change the original licensing agreement. Updated, replacement, and free-credit files remain covered under the original single-classroom or household license. Modified or corrected files may not be shared on public drives, uploaded to district websites, posted in online groups, or redistributed outside your active student roster.
