Key duplication is a great way to have access to your home, car or office in the event that you are locked out. A moment of absentmindedness or forgetfulness can leave you in a bind, but having duplicate keys will allow you to gain entry without having to break the lock and risk any unnecessary damage.
This method involves tracing the outline of your key onto another material such as paper, plastic or an old credit card. The material used must be strong enough to allow the key to be cut out of it, and it can also help to use a sharp object such as a razor blade for a cleaner and more precise result. This method is time-consuming and labor-intensive, but it can be an effective solution for those with hard-to-source key types or those that cannot be replicated using a standard key cutting machine.
Another method of key duplication involves a more sophisticated and expensive machine. The original key is fitted into a vise in the duplication machine, along with a blank key. As the machine operates, the original key is moved along a guide and against a cutting blade, which cuts it into the blank key. The new key is then deburred, which scrubs away any burrs that would otherwise be dangerously sharp and could further foul locks. This is a quick and reliable method of key duplication, but it is not suitable for most modern car keys, which contain chips or transponders that require specialized equipment to copy and program.
