The head of a key that includes a transponder chips can be removed to reveal a steel L-shaped key. Having a replacement key or fob made of transponder chips is a multi-stage process which involves precise cutting of key replacements and programming the transponder chip to synch up with the vehicle's immobiliser system.
Transponders are electronic device with Non-Volatile Memory (NVM) that has a set of windings (very fine wire wrapped around the tube) that look like the ones found in an electric motor. The windings create a coded signal for the car to read. If the code is valid, then the car will allow you to start it.
There are two types of transponder chips, one known as the 80 bit, and the other known as a circle + (General Motors). The former type is reusable but must be delocked by a machine that is specially designed to work in another compatible vehicle.

Immobiliser Systems
An immobiliser is a security measure that uses electronic technology that prevents thieves from starting your car. It operates by sending an electronic signal from the vehicle to the key whenever you try to start it. The electronic chip in your key responds by sending an individual code that must match that of the vehicle in order to start. If the codes do not match, your engine will stop immediately to prevent theft.
Modern smart keys and fobs are equipped with embedded transponder chips that stores security information in a format that cannot be duplicated. When the fob or key are inserted into the ignition, they transmit this code to the ECU. The ECU analyzes this code in comparison to the one stored in its memory, and activates both the fuel system as well as the ignition circuit if they match. If the codes do not match, the engine will not start, even if someone tries to short-circuit the ignition circuit.
