Transponder keys have come standard in most cars manufactured since 2000. This type of key is an integral security feature of most cars, helping prevent theft. If you don’t currently have a transponder key, or you need adjustments to your key, there are plenty of options in the Morrisville, PA area for
car key chip programming, including the experts at Car Keyline. If you’re not familiar with what exactly a transponder key is and why it’s essential, allow us to fill you in!
How Do Transponder Keys Work?
Transponder keys are embedded with a microchip that transmits a signal from the key to the corresponding remote receiver. Programmed by the car’s maker with a serial number unique to that specific car, the microchip must be detected by the remote receiver (in the ignition) before it will allow the ignition to fire.
Transponder keys are intuitively smart. When the driver inserts the transponder key into the ignition, a signal goes out via radio frequency identification (RFID) technology. If the pre-programmed digital serial number in the key’s transponder chip does not match the serial number pre-programmed into the car, then it will not start. If it’s a match, the ignition will fire.
Why Do You Need a Transponder Key?
When it comes to transponder keys, the main emphasis is security, and there are two ways that transponders provide extra protection for car owners. First, they prevent and even deter car theft from “hot wire” events or from breaking the ignition lock since neither of these methods work when a car uses a transponder key. Secondly, a standard ignition key has just a few standard cut combinations, making them easier to duplicate using a key-cutting machine. That is not the case with a transponder key, since it has a digital ID that is unique and cannot be duplicated.
Transponder Key Replacement/Duplication
A trusted locksmith can help you get a replacement or duplicate transponder key. Not all locksmiths have the ability to program transponder keys, so it can be difficult and quite expensive to get a replacement if you don’t have a locksmith with the capacity for replacement or duplication. An alternative (albeit a costly one) is to get a new key from the dealership.
