how to fix my Ford Mustang S650 (2024-Present) remote start not working?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the vehicle battery to ensure safety during repairs.
• Tools Required: OBD-II scanner, multimeter, socket set, fuse puller.

2. Check Key Fob Battery

• Remove the key fob cover using a flathead screwdriver.
• Replace the battery with a new one of the same type (usually CR2032).
• Reassemble the key fob and test the remote start function.

3. Inspect Fuses

• Locate the fuse box, usually found under the dashboard or in the engine compartment.
• Identify the fuse associated with the remote start feature (refer to the owner's manual).
• Use a fuse puller to remove the fuse and inspect it for damage.
• Replace any blown fuses with new ones of the same amperage.

4. Test Vehicle Battery

• Use a multimeter to check the vehicle battery voltage. It should read at least 12.6 volts.
• If the voltage is low, charge the battery or replace it if necessary.
• Reconnect the battery and attempt to use the remote start feature again.

5. Reprogram Remote Start

• If the above steps do not resolve the issue, reprogram the remote start feature.
• Follow the specific procedure outlined in the owner's manual for reprogramming the key fob or remote start system.
• This may involve a series of actions using the key fob and the ignition switch.
