In this article we will cover everything there is to know about this car key replacement service. Read on to learn more about what an automotive locksmith can do for you when it comes to car key reprogramming.
The types of car keys that can be reprogrammed
Electronic car keys come in two main categories. We have hybrid car keys, which are a fusion of electronic and physical keys also referred to as transponder keys. There are also fully virtual electronic car keys which involve using a car key fob. These keys don’t have a metal blade as physical keys do.
If you’re wondering whether you can replace your car remote or keys, read these two brief descriptions so that you can better understand each type. Surely, there are some differences between reprogramming car keys and replacing car fobs.
Transponder Car Keys
If you are dealing with an ignition key that has a blade made of metal you should check whether the key bow has a remote key. The bow is the part that you hold while using the key, usually rectangular or circular in shape. Transponder chips are installed inside the key bow. Thus, by observing this element you can initially determine whether you need to reprogram your transponder key or replace it.
Car Key Fob
