What Does Making Keys to Locks Mean? (The Difference Between Copying and Generating)

Key generation is the process of creating a functional key from the internal dimensions of a lock mechanism. Most people are familiar with standard key cutting, which is simply duplication. You provide a working key, and a machine traces its profile onto a blank. Making keys to locks is different. It’s a technical reconstruction that happens when the original template is missing or unusable.

This process often requires identifying the specific key code associated with the lock. This code acts as a blueprint, detailing the exact depths and spacing of the cuts needed to align the internal pins or levers. Without this code or a physical key, a locksmith must use forensic techniques to “read” the lock from the inside out.

When Duplication Isn’t an Option

There are three common scenarios where duplication fails. First, the most obvious: you’ve lost your only set of keys. Second, your current key might be so worn or bent that it no longer operates the lock reliably. A copy of a bad key is just another bad key. Third, we often assist clients who have inherited antique furniture or moved into properties with locked heritage cabinets. In these cases, making keys to locks allows you to keep the original, beautiful hardware while restoring its function.

How Locksmiths Create Keys Without an Original: 3 Professional Methods

Generating a key from scratch requires a deeper level of technical knowledge than simple duplication. The approach we take depends entirely on the lock type and its security grade. At London Locks, we focus on non-destructive methods to ensure your hardware remains intact. As Tower Hamlets’ only approved master locksmiths and an ABS and EVVA super centre, we have the specialized equipment required for these forensic tasks. For every technical job, we ensure transparency. Fixed quotes given. No surprises.

1. Impressioning: The Art of Reading the Lock

Impressioning is a traditional skill that allows us to create a key without taking the lock apart. We start by inserting a specific key blank into the keyway. By applying torque and manipulating the blank, the internal pins or wafers leave tiny, almost microscopic “marks” on the metal. We then use a precision file to cut the blank at these exact locations. This process is repeated until the key turns the lock perfectly. It’s a methodical way of making keys to locks that preserves the integrity of the cylinder.

2. Decoding and Cutting by Code

Many modern high-security locks, like the EVVA EPS system, rely on a specific key cutting code. This code might be found on a security card or stamped on the internal components. We use advanced decoding software to translate these numbers into exact bitting depths. Once we have the data, our computer-controlled machines at our Bow Road shop cut the key with 100% accuracy. This method is fast, efficient, and eliminates human error.

3. Disassembly and Direct Measurement

For some complex cylinders where impressioning is difficult, we may need to disassemble the mechanism. We carefully remove the plug to access the internal pins or discs. By measuring these components with digital calipers, we determine the exact dimensions needed for the new key. After cutting the key, we reassemble the lock to its original security standard. This ensures your high-security cylinder continues to function as the manufacturer intended.

Our physical shop is located at 143 Bow Road, London, E3 2AN. We are available to help from 0900 to 1800, Monday to Friday. Please note that our shop is closed on Saturday and Sunday. Whether you need a key for a modern door or a complex heritage piece, we provide the expertise needed to restore your security without the cost of a full lock replacement.

Making Keys vs. Changing Locks: Which Is Right for Your Security?

Many homeowners assume that buying a new lock is always cheaper than calling a locksmith to create a key. This is a common misconception. Making keys to locks is often a more sustainable choice for high-security cylinders from brands like EVVA or ABS. Replacing a specialized high-security unit can be expensive. In contrast, the labor cost to generate a new key for that existing hardware is frequently much lower. We maintain a policy of complete transparency regarding these costs. Fixed quotes given. No surprises.

Security isn’t just about functionality; it’s about compliance. If your current lock doesn’t meet BS3621 standards, making a new key won’t help your insurance standing. British Standard locks are a requirement for most home insurance policies in London. As Tower Hamlets’ only approved master locksmiths, we evaluate your hardware to ensure it provides the protection you need. We don’t just make keys; we ensure your property remains a hard target for intruders.

When to Choose Key Generation

Choosing to generate a key is the smart move for high-value hardware. If you have expensive cylinders from Mul-T-Lock or EVVA, the cost of the hardware itself makes replacement a last resort. This method is also essential for heritage or antique locks where the original brass or ironwork is irreplaceable. Additionally, if you have multiple doors keyed alike, generating a new set of keys allows you to keep that convenience without the massive expense of replacing every lock on the property.

When a Lock Change is Better

There are times when a full lock change is the only responsible option. If your lock is physically damaged, seized, or doesn’t meet modern security standards, a replacement is necessary. You should also consider a lock change if you suspect your lost keys are in the hands of someone who knows your address. This is a critical security breach that key generation cannot fix.

Specialist Key Making in London: From Heritage Locks to EVVA Systems

London’s architecture is a diverse tapestry of history, ranging from grand Georgian townhouses to cutting-edge modern developments.

When we’re making keys to locks for these high-security systems, we use computer-controlled machinery to ensure the bitting is accurate to a fraction of a millimeter. Visiting an MLA-approved shop gives you the guarantee that your security data is handled professionally and your new keys will work perfectly every time.

Frequently Asked Questions

Can a locksmith make a key from a lock without the original?

Yes, a professional locksmith can generate a new key using the internal dimensions of the mechanism. This process, known as making keys to locks, involves impressioning the cylinder or decoding the internal pins. We use specialized equipment to “read” the lock from the inside. This allows us to create a perfectly functioning key even when the original is missing or broken beyond repair. It is a technical reconstruction that requires master locksmith precision.

How much does it cost to have a key made to a lock?

The cost varies based on the type of lock and the level of security required. High-security cylinders like EVVA or complex heritage locks require more technical labor than standard domestic locks. We maintain complete transparency with our pricing policy. Fixed quotes given for every job, ensuring there are no surprises when you receive the bill. We evaluate the hardware first to provide an accurate assessment of the work involved in restoring your access.

Is it cheaper to make a new key or replace the whole lock?

It is often significantly cheaper to generate a new key for high-quality hardware rather than replacing the entire unit. High-security ABS or EVVA cylinders are expensive to purchase new. By generating a key, you save the cost of the hardware while maintaining your current security standard. However, if the lock is old and doesn’t meet BS3621 insurance standards, we might recommend a full upgrade to ensure your property remains compliant and protected.

Can you make keys for old antique or heritage locks?

Yes, we have the niche capability to generate keys for Victorian and Georgian heritage locks. These antique mortice and rim locks are common in East London properties and require traditional hand-filing skills. We preserve the original aesthetic of your period hardware while restoring its full mechanical function. This service is essential for homeowners who want to maintain the historical integrity of their property without compromising on the security of their doors or cabinets.

How long does it take to generate a key from a lock?

The timeframe depends on the complexity of the lock and the method used. Simple locks can often be decoded or impressioned within thirty minutes to an hour. More intricate high-security systems or antique locks may require a few hours of precision work. We prioritize accuracy to ensure the new key operates smoothly without causing wear to the internal pins. We’ll provide a clear time estimate when we evaluate your specific locking mechanism.
