Key Cutting

How Do We Get Keys Unstuck?

One of the most useful tools in a local locksmith’s arsenal is the key extractor. This slender, hook-shaped instrument is designed to remove broken or stuck keys from locks. Key extractors come in different sizes to accommodate various keyway dimensions.

When a key breaks inside a lock, it can be a frustrating and challenging situation. However, a locksmith with a key extractor can quickly and efficiently resolve the problem. By carefully manoeuvring the key extractor, the locksmith can grasp the broken key and safely extract it, allowing for the lock to be operational once again. This technique saves both time and money by avoiding the need for lock replacement. At Assist Locks, non-destructive techniques such as this one are always prioritised and attempted first.

Tension Wrenches

Tension wrenches, also known as torsion tools, are fundamental for lock picking. These tools are used to apply pressure to the lock’s cylinder while manipulating the pins or tumblers inside. By carefully adjusting the tension and using the correct techniques, a skilled locksmith can feel the pins set into place, eventually unlocking the mechanism.

The correct application of tension is crucial when using a tension wrench. Too much pressure can cause the pins to bind, making it difficult to manipulate them. On the other hand, too little pressure might not provide enough resistance for the pins to engage properly. Skilled locksmiths understand the delicate balance required and can effectively use tension wrenches to pick locks with precision and accuracy.

Lock Picks

Lock picks are the bread and butter of a locksmith’s toolkit. These thin, metal instruments come in various shapes and designs to accommodate different lock types. Hook picks, diamond picks, and rake picks are just a few examples of the tools a locksmith might use to navigate the intricacies of different lock mechanisms.

Using lock picks requires a combination of technical knowledge and tactile finesse. Each lock pick has a specific purpose and technique associated with it. For instance, hook picks are used to individually lift and set each pin, while rake picks are used to rapidly manipulate multiple pins simultaneously. A skilled locksmith knows how to select the right pick for the job and employ the appropriate technique to unlock the mechanism. It takes many years to master lock picking, but it provides a great way to access properties with minimal disruption.

Key-Cutting Machines

Key-cutting machines are essential for locksmiths who provide key duplication services. These machines are designed to accurately replicate keys by cutting them to the same shape and size as the original. With the right key-cutting equipment, a locksmith can quickly and efficiently create spare keys for customers, ensuring their peace of mind and convenience.

Key-cutting machines come in different models, from manual to electronic. A locksmith uses the original key as a template to guide the machine’s cutting mechanism, ensuring precise duplication. This process is especially valuable when customers require spare keys for their homes, offices, or vehicles. An experienced locksmith can swiftly operate a key-cutting machine to produce accurate duplicates, saving time and hassle for the customer.
