Transponder Key Cutting

Counties Locksmiths can cut transponder keys by code for almost any vehicle. We can make transponder keys for cars even when codes are not available. Send us a lock from the car and we can generate a transponder key for it. This will usually give you a complete working transponder key for the car.

What are Automotive Transponder Keys?

The biggest change to the automotive industry in recent times has been the introduction of the built in immobiliser system on all modern cars.
This involves placing a microchip in the head of the transponder key, which is a miniature transmitter and receiver. There is an engine management system in the engine compartment that can recognise the signals transmitted from the transponder key.
If the correct signals are not detected the engine will not start.

How does the Transponder Key work?

An electronic chip with a permanent memory which contains an electronic code. The transponder key has an antenna with which it can interface with an external electronic control device.

Through the antenna the device emits a fixed frequency signal; the transponder key receives the signal and then transmits its electronic code, by means of special frequency modulations, to the control device, which is able to process the code.

The transponder key has no external input of power supply (passive system); it receives the energy necessary to work from the signal emitted by the external control device (inductive coupling between the control device antenna and that of the transponder key).
