Information about your Lexus transponder car key fob

Many Lexus car keys have been manufactured with a tiny electronic chip embedded. This chip, known as a transponder, allows the vehicle to start.

The transponder communicates with the immobiliser unit of the Lexus, which is typically concealed behind the dashboard of the car. When a car key is inserted and turned in the ignition, the Lexus immobiliser system will electronically search for a corresponding transponder.

Upon identifying the correct chip, the immobilisation system then allows the Lexus to start up. In the event of the system failing to detect a transponder, the engine's fuel supply is disengaged. This makes it impossible to remove, bypass or override the Lexus' immobiliser system in order to drive the car.

Does my Lexus have a Transponder Chip?

All Lexus models manufactured after 1995 utilise transponder chip technology within the ignition key.

The microchips, which are embedded in the plastic part of Lexus key fobs, operate on one of two unique coding systems. Newer vehicles make use of a crypto code system, whereas older models utilise a "red key" security system.

In order to duplicate keys for older vehicles operating on the red key system, the original red master key is typically required in order to electronically pair and match a replacement key to the vehicle.

Duplicating or replacing a Lexus car key

There are numerous stages to replacing a Lexus key. Firstly, a new key blade must be accurately cut and shaped in order to allow it unlock the car doors as well as fitting in the ignition. Following this, a transponder chip within the duplicate key must be programmed to match the vehicle.

This is important, as if the Lexus key is incorrectly programmed it will allow entry to the vehicle, but will not permit the vehicle to start up.

Procedures differ for remote fobs, which must be synchronised to the individual Lexus in order to lock and unlock the car doors.
