Car keys made with Transponder Chip

Now, when it comes down to car keys, a commonly asked question is why do they cost so much to replicate? Well, the reason is usually set within the very nature of the key. There are two basic types – flat metal keys and those that have a transponder chips. The first one is pretty self-explanatory, and they wouldn’t usually cost you so much.

Some of these remotes are usually built into the keys, and that’s what we like to call a remote head key, while others are going to be separated from the keys. These particular remotes are independent parts which operate separately from the transponder system.

So, when it comes down to the transponder key, it’s worth noting that this is a part of the anty-theft securities of the vehicle.

Things to Consider

The very word “transponder” comes from two separate ones – transmitter and responder. Basically, this is a small microchip which is embedded in the plastic head of your key, and that’s going to receive a particular signal from the vehicle. This signal is emitted through an antenna ring which is located under the cylinder for the ignition. Once the signal is emitted, the computer of the vehicle has to receive the adequate response from the transponder key. If this fails to happen, the computer won’t allow the vehicle to start operating. It’s pretty convenient when you come to think of it as it is going to significantly going to reduce the theft possibilities.

Modern Advancements

Now, with the advancement of high-tech solutions, the transponder system is also taking leaps forward. The most contemporary systems use an encryption which is contained of a rolling code. This suggests that the password that the transponder system is taking usage of is going to change every single time it’s used.
