Solution

1. Preparation

Gather necessary tools: mobile device with the Tesla app, access to Wi-Fi, and potentially a new key fob battery.
Ensure the vehicle is parked in a safe location with sufficient battery charge.

2. Update Software

Open the Tesla app and go to 'Software' to check for updates.
If an update is available, follow the prompts to download and install it.
Ensure that the vehicle is parked and connected to Wi-Fi during the update.

Remove the key fob cover using a small flat-head screwdriver.
Replace the old battery with a new CR2032 battery, ensuring the positive side is facing up.
Reassemble the key fob and test for functionality.

4. Check 12V Battery

Open the front trunk (frunk) and locate the 12V battery.
Use a multimeter to check the voltage; it should be around 12.6 volts or higher.
If the reading is low, consider charging or replacing the 12V battery.

5. Reset Connectivity

Power cycle the vehicle by pressing and holding the brake pedal, then pressing and holding the two scroll wheels on the steering wheel until the screen resets.
Wait for the system to reboot and reconnect to the mobile app.
