The Art of Opening Locked Doors: Insights from a Professional Locksmith

As a professional locksmith, I have encountered numerous situations where people have found themselves locked out of their homes or offices. It can be a frustrating and stressful experience, but fortunately, there are various techniques and tools that we use to open locked doors without causing any damage. In this article, I will share my expertise and insights on how locksmiths open locked doors.

The Cylindrical Grill Method

The cylindrical grill method is a destructive entry technique that is usually at the bottom of a locksmith's list. This method involves strategically drilling the cylindrical lock to open the door, which ultimately results in the lock being replaced with a new one.

While this method may seem extreme, it is often necessary in emergency situations where there is no other way to gain entry into a locked door. At Calder Security, we have been members of the Master Locksmiths Association (MLA) since 1976 and have extensive experience in working with a wide range of locking mechanisms. We always strive to use non-destructive methods first, but in some cases, the cylindrical grill method may be the only option.

The Anti-Knock Wrench

The anti-knock wrench is one of the oldest tools used by locksmiths to open doors. It is highly effective on conventional toilet locks and can be used on almost all types of doors. This tool works by inserting a modified hexagonal key into the keyhole and attempting to open the lock as if it were the real key.

Many locksmiths sharpen the end of their hexagonal wrenches to create a "U" shape with two raised edges and a groove in the middle. This technique is primarily used for opening frozen locks, where the pins inside the lock align perfectly with the key. It is important to note that this method should only be used by trained professionals, as using it incorrectly can cause damage to the lock and door.

Proactive Lock Care

As a professional locksmith, I always recommend being proactive when it comes to taking care of your locks. Regular maintenance and servicing can help prevent lockouts and ensure that your locks are functioning properly. This not only maximizes your safety and security but also helps build a good relationship with a trusted locksmith in your area. Locksmiths have a specialized set of tools that includes picks, screwdrivers, and drills, which are used depending on the type of door and locking mechanism.

While the design and materials of these tools have improved over time, their basic function remains the same.

Programming Skills

With advancements in technology, many modern locks now require programming skills to open them. This is where the expertise of a professional locksmith comes in. Unlike untrained handymen, locksmiths have the necessary skills and knowledge to work on these types of locks without causing any damage. It is important to note that not all locksmiths have programming skills, so it is essential to choose a reputable and experienced locksmith for these types of locks.

The Importance of Experience

One of the main reasons why it is crucial to hire a professional locksmith is their experience. Opening locked doors may seem like a simple task, but it requires a certain level of skill and experience to do it correctly.

Professional locksmiths have years of experience working with various types of doors and locking mechanisms, making them well-equipped to handle any situation. In addition to their technical skills, experienced locksmiths also have the necessary tools and equipment to open doors without causing any damage. They understand the intricacies of different types of locks and know how to manipulate them to gain entry without breaking or damaging the lock or door.


In conclusion, opening locked doors is an art that requires a combination of skill, experience, and specialized tools. As a professional locksmith, I have seen firsthand the frustration and stress that comes with being locked out. That's why I always recommend being proactive in taking care of your locks and having a trusted locksmith on hand for emergencies.

Remember, when it comes to opening locked doors, it's always best to leave it to the experts.
