Our sliding glass door lock broke and we needed help to secure the door, Leo from Los Angeles Lock & Safe came over and quickly installed a new lock and adjusted the door so it was locking easily. Leo also showed us an easy and simple way to secure the door with just a metal rod that fits into the track and prevents the door from moving, which was a great tip and we adopted it instantly. Leo is great guy, very polite, professional and clearly very experienced, we are very pleased with his work!
