Q: Why don’t I hear a “click” when locking or unlocking? The “click” means the latch is engaging properly. If you don’t hear it, the push rod may have been cut incorrectly. Remove the latch and double-check the first installation step.
Q: Why won’t my key turn fully? This is often caused by an incorrect push rod length, which can stop the mechanism from moving fully. Remove the latch and check that the rod is the correct length.
Q: Why isn’t the latch locking or unlocking properly?
If the push rod is too long or too short, it can affect how the latch works. Re-check the installation steps and adjust the rod if needed. We supply a spare rod.
Q: What should I do if the problem continues? Revisit the first installation step and confirm the push rod length. If you still have issues, please visit our website and contact your local D&D support team for help www.ddtech.com
