When hiring a lock replacement service, always verify the technician's credentials and licensing to avoid scams or subpar workmanship. Ensure the service provider uses high-quality, certified locks that meet security standards for your specific application. Before installation, confirm that the new lock is compatible with your door's thickness and existing hardware.
