The most common cause of unauthorized entry through a locked door is by using a duplicate key. Standard keys to your property or business can be made on demand in countless places. Malibu Locksmiths suggestion is to replace standard locks with high security products by Mul-T-Lock because each Mul-T-Lock key has a personal identification card that prevents duplication without the property resident permission. We are an authorized Mul-T-Lock dealer for the entire Los Angeles area and we highly recommend high security locks for your home, apt and business.
