how to fix my Ford Mustang S650 (2024-Present) remote start issues

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface with the engine off.
• Disconnect the battery to avoid any electrical shorts during the repair.

2. Replace Key Fob Battery

• Remove the key fob cover using a small flathead screwdriver.
• Replace the old battery (typically a CR2032) with a new one, ensuring correct polarity.
• Reassemble the key fob.

3. Check and Charge Vehicle Battery

• Use a multimeter to check the battery voltage; it should read around 12.6 volts for a fully charged battery.
• If the voltage is low, connect a battery charger and charge the battery to full capacity.

4. Inspect Fuses

• Locate the fuse box (refer to the owner’s manual for location).
• Check the fuse for the remote start system and replace it if blown.
• Use a fuse puller or pliers to remove and replace the fuse with one of the same amperage.

5. Verify System Functionality

• Reconnect the battery and ensure all connections are secure.
• Attempt to use the remote start feature again, ensuring the vehicle is in park and all doors are closed.
