Today, I want to show you how to replace the car key battery (CR2032 3V) Toyota Fortuner without any tools.

When to change the car key battery?

1. The alarm/notification "Key battery low" appeared on the display meter after the engine started.
   
2. No LED light when pressing button keys.
   

Step:

1. Slide the lock to the right at the backside of the electronic key and pull out the mechanical key.
   
   
   
   
   
   
   
   
2. You can see the slotted behind inside the mechanical key places.
   
   
   
   
   
3. Inside the mechanical key inside the slotted and give a little twist to it.
   
   
   
   
   
4. The two pieces will come apart.

6. The battery type is CR2032 3V from Panasonic.
   
   
   
   
   
7. For replacement, I used a CR2032 3V battery from Energizer.
   
   
   
   
   
8. Install all components in reverse order of removal. Note: Ensure the positive (+) is outside and negative (-) inside.

Today, I want to show you how to change the gear oil for SYM 125 Jet Power scooter. Most scooters should have a gear oil change between 3000 KM to 5000 KM or 5 months.

What happens if you do not change the gear oil?

1. Corrosion to the gearbox.
2. Gear failure.
   
   

When to change the gear oil?

1. Every 5000 KM or 5 months, whichever comes first.
