why is my Honda Accord 10th Generation (2018-2022) having issues with remote start

Solution

1. Preparation

• Tools Required: OBD-II scanner, multimeter, replacement key fob battery, screwdriver set.
• Ensure that the vehicle is parked in a well-ventilated area and that the engine is off before beginning repairs.

2. Battery Check

• Use a multimeter to measure the battery voltage.
  • If voltage is below 12.4 volts, charge or replace the battery.

3. Remote Key Fob Battery Replacement

• Remove the back cover of the key fob using a small screwdriver.
• Replace the old battery (typically CR2032) with a new one, ensuring correct polarity.
• Reassemble the key fob and test the remote start function.

4. Door and Hood Sensor Inspection

• Inspect each door and the trunk to ensure they are properly closed.
• Open and close the hood, checking for proper latch engagement.
• If the hood latch is malfunctioning, it may need cleaning or replacement.

5. Diagnostic Trouble Code (DTC) Clearing

• Connect the OBD-II scanner to the vehicle's diagnostic port.
• Check for any trouble codes and note them.
• Clear the codes and test the remote start function again.

6. Check for Interference

• Inspect for any aftermarket installations that might interfere with the remote start system.
• Disconnect any suspicious devices and test the remote start again.
