Frequently Asked Questions
Can I install a high-security strike plate on any door?
Most doors accommodate these plates, but you must check your frame's clearance first. You need enough wood behind the jamb to house the longer screws without splitting the timber. If you have a metal frame, you will need specialized masonry fasteners instead.
Are keyless locks as secure as traditional keys?
Modern smart locks are incredibly reliable, but their security depends on your digital hygiene. Use complex, unique codes and avoid sharing your master password. If the battery dies, ensure your model has a physical override key hidden in a secure spot.
What is the most common point of failure for front doors?
The door frame itself is usually the weakest link. Even a military-grade deadbolt will fail if the wood around the strike plate is soft or rotting. Reinforce the frame with a steel wrap-around plate to prevent the wood from splintering under pressure.
Do I need a professional to install these devices?
If you are comfortable with a power drill and a screwdriver, you can handle most installations yourself. Replacing a standard deadbolt is a straightforward job that takes about 30 minutes. Only call a locksmith if you need to modify the door hole or rekey multiple locks to match one key.
Will a smart lock drain my phone battery?
Smart locks use Bluetooth Low Energy or Wi-Fi, which has a negligible impact on your phone. Most of the power consumption happens at the lock itself, not your mobile device. Keep an eye on your lock's battery levels through the app to avoid getting locked out.
