Step-by-Step Troubleshooting
Follow these steps to troubleshoot and fix a garage door that won’t lock:
1. Inspect the Locking Mechanism
Start by closely examining the lock on your garage door. Ensure that it is not stuck or damaged. A simple lubrication can often resolve minor issues.
- Apply lubricant to the moving parts of the lock.

2. Check for Misalignment
A misaligned garage door can prevent the locking mechanism from engaging. To check for alignment:
