Solution

1. Preparation

Gather necessary tools and parts.
Ensure vehicle is in a safe location with adequate space around it.

2. Check and Replace Key Fob Battery

Using a small flathead screwdriver, gently pry open the key fob.
Replace the old battery with a new CR2032 battery, ensuring correct polarity.
Reassemble the key fob and test the remote start function.

3. Inspect and Charge Vehicle Battery

Open the hood and visually inspect the battery for corrosion or damage.
Use a multimeter to check the battery voltage; it should read above 12.4 volts.
If voltage is low, connect a battery charger and allow it to charge for several hours.

4. Verify Door and Hood Closure

Ensure all doors and the hood are completely closed.
Manually check each door lock mechanism and hood latch for proper operation.
Attempt to remote start the vehicle again.

5. Reset Security System

Insert the key into the ignition and turn it to the "On" position without starting the engine.
Leave it in this position for about 10 minutes until the security light turns off.
Turn the key back to the "Off" position and then attempt to use the remote start.
