ID48 - TP-08 Megamos Crypto EM4170 glass transponder chip

This type of transponder is generally known as a cloning chip in that it can be used to clone or copy the information from your existing key to make an exact copy of it. The vehicle will see boths keys as being the same key.

This type of cloning can only be carried out using special equipmet instore. 

ID 48 chips can also be programmed directly to a vehicle if they are pre-coded. These types of programmable chips are not user programmable and so can only be coded to the vehicle using special equipment and will generally need a manufacturer pin-code or security code for this process.

This type of chip is known as a glass transponder as the electronics are inside a glass shell an so great care must be taken when handling these types of chips. The chip only measures 13 mm x 3 mm so can be easily lost.

Without a transponder chip in the key head of the key, the car will not start as this transponder chip contains security information that the car looks for every time the ignition it turned to start the car.

There are a few versions of these glass chips and all have different types of information in them or are compatible with different cloning machines or some can only programmed directly and not cloned.

Unlike the carbon chips which have a code printed on them, glass transponders do not and so can only be identified by reading them with a scan tool or cloning tool.
