What features make a garage door system more secure against break-ins?

Most modern openers use rolling code technology, which changes the signal every time you use your remote so it cannot be captured and reused, unlike older fixed code systems. Look for a vacation lock feature that disables the remote and keypad while you are away, plus a keypad with its own rotating code instead of a static PIN. On the door itself, a reinforced deadbolt or slide lock adds a mechanical backup in case the opener is ever bypassed.
