Over the last 30 years of operation in the locksmith industry, we have witnessed people either locked out or in their cars, broken their car keys, and even worse, lost their keys. If and when that happens, you have to replace it. But what if you have to make the replacement car key without the original? This blog details whether you can program a transponder key without the original.

First, let’s define a transponder key:

What is a transponder key?

A transponder key is a security device built with a microchip (transponder chip) that uses radio waves to transfer unique alphanumeric codes to your vehicle’s ignition system. With the sent codes, your vehicle’s ignition will come ON. Any vehicle designed with a transponder key will not function without that programmed initial key. You might be wondering what would happen if you can’t find any of your original keys – well, we’ll get into that in the next step.

You should know that any vehicle manufactured with a transponder key will not function in the absence of that key. Except you either have a master key or contact a locksmith; to help you create a matching transponder key or your car dealer. So, back to the question of ‘whether a transponder key can be programmed without the original’ – the answer is YES.
