Antenna door opening Renault Megane 2

Cars equipped with the "hands-free" system have presence sensors and antennas for opening body elements for card recognition:

• - opening antenna in the outside handle of each door,
• - opening antenna in the rear bumper,
• – presence sensor in the outside handle of each door.

The engine start antennas have no effect on unlocking the vehicle.

On the contrary, it is not possible to lock the car using the "lock" switches located on the outside handles if the card is in the engine start area.

Movement sensors are built into presence sensors.

Remove antennas

For hands-free operation, the outside door handles are equipped with:

• - presence sensors to recognize the user's hand in combination with a reflector mounted on the handle;
• - lock button;

- opening antenna built into the handle (Fig. 2)

Only vehicles equipped with a hands-free system have a lock switch.

If the vehicle has not been used for approximately 72 hours, the presence sensors are disabled.

Detection of the command to unlock, in this case, is carried out by the handle movement sensor.

Presence sensor and handle movement sensor are assembled.

Removing the rear antenna

Remove the rear bumper.
