Access, protection


It is not necessary to leave children unguarded in the car if in it there are keys, especially if the key is inserted into the ignition lock. Children are accustomed to imitate adults and can insert a key into the ignition lock and include ignition or start the engine. It can lead to injuries of children when using, for example, of power windows or to road accident if the car begins to move.

Together with the car two clue and a plate with their code are furnished.

1 — the Main key
2 — the Additional key
3 — the Plate with a code

The main key (with a head of black color) approaches all locks of the car and can be used for start of the engine. This key together with its code needs to be provided to the representative of the Lexus company if it is required to make a twirl with the built-in transponder of an immobilizator.

The additional key (with a head of gray color) approaches all locks of the car, except the lock of a ware box, and can be used for start of the engine.

The code of keys should be rewritten on paper and to store it together with a plate in the reliable place inaccessible for strangers (only not in the car!).

For normal work of an immobilizator at start of the engine, do not assume that the charm of the ignition key was over its head, and also that on one brelk there were several keys with transponders. In order to avoid damage of the transponder do not subject to its influence strong mechanical loadings (deformations, blows), high temperatures, moisture and strong Ý/m fields.
