Solution

1. Key Fob Battery Replacement

• Tools Required: Small flathead screwdriver, CR2032 battery
• Open the key fob using the small flathead screwdriver to pry apart the two halves gently.
• Remove the old battery and replace it with a new CR2032 battery, ensuring the correct polarity (+/-) is observed.
• Snap the fob back together securely.

2. Check and Reset Keyless Entry System

• Tools Required: OBD-II scanner
• Connect the OBD-II scanner to the vehicle’s diagnostic port.
• Retrieve any error codes related to the keyless entry module.
• If codes are present, clear them and attempt to test the keyless entry system again.

3. Inspect Keyless Entry Receiver Module

• Tools Required: Socket set, multimeter
• Locate the keyless entry receiver module (usually in the rear compartment or under the dashboard).
• Disconnect the module's connector and inspect for corrosion or damage.
• Using a multimeter, test for continuity and proper voltage supply to the module.
• If the module is faulty, replace it with a new one.
