What is a transponder and how do they operate?
The word transponder is basically a shortened version of the words "Transmitter" and "Responder". In this case it is a miniaturized electronic chip that has a nonvolatile memory; this type of memory does not need a source of energy for retention. The chip is accompanied by a fine wire coil, which acts as a transmitter.
The transponders used on vehicles today are known as "Magnetic Coupled Transponder Systems". These systems are passive in nature and therefore do not require constant electricity or their own power supply. They tend to operate at a frequency of around 125KHz and their range is limited to about 15cm.
The transponder chip itself does not have to be directly visible to be able to communicate. Its radio frequency can pass through materials such as rubber and plastic.
A transponder system functions around two primary components, the processor/interrogator and a transponder microchip embedded in the head of the ignition key. The processor interacts with the vehicles engine control unit (ECU). When an attempt to start the vehicle is made, the interrogator sends a radio frequency to an antenna (which is usually situated around the face of the ignition barrel). The radio frequency contains a code number, which is usually made up of a 32 digit alphanumeric sequence. If the processor recognises the code sent by the interrogator, the vehicle will be allowed to start. If the code does not match, the vehicle may start temporarily, then shut down, or it may not start at all.
Manufacturers currently developing transponder systems are Philips, Texas Instruments, Temic and Megamos. Each having their own idiosyncrasies regarding cloning duplicate keys.
Some transponder keys can be cloned using reader/encoder hardware and writeable transponder chips. Others must be programmed into the processor/interrogator before they will function, this technique is known as "programming the key via the vehicle". The remaining systems that are not coded using the aforementioned techniques, must be cloned using specialised diagnostics equipment.
There are currently three types of vehicle transponder system:
Fixed Electronic Code
Each key has a different electronic code written to it. These codes are permanent, they are not altered when the engine is started.
Rolling Electronic Code
Each key has a different electronic code, which is re-written each time the engine is started. Only the immobilizer manufacturer knows the procedure by which the code is changed.
Cryptographic Electronic Code
The transponder memory is protected using bi-directional encryption of data. Internal algorithms are configured to interpret the messages sent from transponder to ECU. This is similar to password protection.
Keys can be Cut to Code, Keys made to Locks, Locks made to suit your key, Transponder keys copied,Crypto keys programmed,and Remote Key Fobs supplied and coded.
Most vehicle manufacturers keys & remotes cut & programed to your car please call for details.
