How to Repair the Lock on a Sentry 1170

You have important documents stored in your Sentry 1170 safe, but you can't get them because the key won't open the lock. When this happens there may be a structural or mechanical defect with the lock. If this is the case, Sentry will repair it for free under its 1-year warranty. However, not all lock problems are mechanical or structural. It's a possibility that dirt, dust and other debris are clogging the lock. If so, there's a simple method that will open the lock in a matter of minutes.

Instructions

    • 1

      Examine the letters that are engraved on your key. Check the letter engraved on the key-lock cylinder. Make sure the letter on the key and the key-lock cylinder match.

      Spray the inside of the lock with WD-40. The WD-40 lubricates the lock and helps dissolve any debris that's inside.

    • 3

      Tap the lock gently with the hammer. Tapping the lock loosens up any remaining dirt, dust or other debris.
