If you own something with a motor, you have a set of keys to go with it. From starting your engine to unlocking your door, your key (as you already know) plays a multifaceted role. That said, should the time arise that your keys become lost or broken, you’ll be faced with the choice of auto key duplication or replacement.

So, which do you chose? Here, Speed Of Sound Audio Experts are talking about the differences.


Auto key duplication.

Depending on the need, key duplication is often the quicker, more affordable option. However, if your keys have been lost or stolen, this may not be the best option.

Key duplication utilizes data embedded within the transponder to create an identical replication. Thus, if your keys are lost or stolen, making a duplicate doesn’t protect you from potential theft. Besides, it’s often impossible to gather the needed data without the original key to abstract the codes from.

Instead, this option is best if you’re looking for extra keys, duplicates. However, it’s important to remember that a duplicate can not be used in the event of a lockout. In this instance, the original (or a replacement) will be the only way to gain access to your vehicle.


Auto key replacement.

On the other side, key replacement completely reprograms the key with your vehicle’s computer system. This option tends to be the most versatile as it can be used even if the original is not available. While returning to the dealer is an option, the more affordable way to obtain a key replacement is to give Speed of Sound a call.
