1. When the key is inserted into the lock hole, the lock lever can be inserted into the first gear. At this time, only the function of the lock can be turned on, and no alarm can be given.

 2. If you need an alarm, please twist the lock cylinder with the key to insert the lock lever into the second gear. After 30 seconds, you can not only lock the car but also give play to the alarm function.

 If the battery is to be replaced, please pull out the lock lever first, then screw out the two screws of the cover plate engraved with the battery logo, and then take out the cover plate and the battery, so that it can be replaced.
