Keyless entry with answerback function. ● Product Overview This aftermarket keyless entry kit adds lock, unlock, and answerback functions to vehicles with a central door locking system using a single remote control. Since you don't need to insert and turn a key in the door, locking and unlocking is much easier when you have a lot of luggage or on a rainy day. The answerback function allows you to confirm the car's location with hazard lights flashing when operating the remote control, and you can also confirm the locked status. By installing the included dummy light, you can enhance the security effect. ● Set Contents  Main unit  2 remote controls (with batteries)  Main unit wiring cable: approx. 50cm  Dummy security LED + 1m cable  English instruction manual ● Remote Control Operation ① Lock  Press the lock button on the remote control once, the turn signals will flash once, the doors will lock, and the dummy security lamp will start flashing.  If a siren (horn) is connected, it will sound once when locking. ② Unlock  Press the unlock button on the remote control once, the turn signals will flash twice, and the doors will unlock.
