Key duplication is an essential service used by homeowners, car owners, businesses, and individuals worldwide. Whether you've lost your key, need a spare, or want to provide access to someone else, key duplication ensures you always have the right access at the right time. Below is a comprehensive guide covering everything you need to know about key duplication.
What is Key Duplication?
Key duplication is the process of creating an exact replica of an existing key using specialized key cutting equipment. It involves cutting a blank key to match the original key's unique grooves and patterns to ensure it operates the intended lock smoothly.
Types of Keys That Can Be Duplicated
1. House Keys
House keys are the most common type duplicated. They include keys for front doors, back doors, interior doors, gates, and padlocks.
2. Car Keys
Car key duplication includes traditional car keys, transponder keys, and modern key fobs. Some may require programming after duplication.
3. Office and Commercial Keys
Businesses often need duplicate keys for staff, maintenance teams, and security purposes.
4. High-Security Keys
These include restricted or patented keys that may require authorization for duplication. Specialized machines and certifications are often needed.
5. Mailbox and Cabinet Keys
Small format keys for lockers, cabinets, and mailboxes can also be duplicated easily.
The Key Duplication Process
Step 1: Selection of a Blank Key
A blank key that matches the make and model of the original key is selected.
Step 2: Key Cutting
Using a key cutting machine, the locksmith or technician aligns the original key and the blank key. The machine traces the original key's pattern and cuts the blank key accordingly.
Step 3: Finishing Touches
The new key is polished and checked for any burrs or rough edges.
Step 4: Testing
Before handing over the key, the technician often tests it to ensure it works perfectly in the corresponding lock.
Advanced Technologies in Key Duplication
1. Laser Key Cutting
For precision keys (like automotive and high-security keys), laser cutting machines offer higher accuracy.
2. Computerized Key Duplication
Modern key duplication services use software to scan and cut keys with digital precision.
3. Transponder Key Programming
For many modern vehicles, duplicating the key isn’t enough. The transponder chip also needs programming to start the vehicle.
Common Reasons for Key Duplication
Lost or misplaced keys
Spare keys for family or roommates
Business access for multiple employees
Moving into a new property
Emergency backup keys
