why won't my Toyota Corolla E170 (2013-2019) power locks work

Solution

1. Preparation

• Gather tools and parts before starting the repair.
• Tools Required: OBD-II scanner, multimeter, flathead screwdriver, Phillips screwdriver, replacement fuses (if needed), key fob battery.

2. Replace Blown Fuses

• Locate the fuse box, typically found under the dashboard or in the engine compartment.
• Remove the fuse panel cover.
• Identify the fuse related to the power locks (refer to the owner's manual for location).
• Inspect the fuse for continuity; if blown, replace it with a new fuse of the same amperage.
• Reinstall the fuse panel cover.

3. Test and Replace Power Lock Switch

• Remove the trim panel around the power lock switch using a flathead screwdriver.
• Disconnect the electrical connector from the switch.
• Use a multimeter to test for continuity across the switch terminals when pressed.
• If the switch is faulty, replace it with a new one and reconnect the electrical connector.
• Reinstall the trim panel.

4. Repair or Replace Wiring

• If wiring damage is found during inspection, carefully repair the damaged wires using electrical tape or solder.
• Ensure all connectors are securely attached and not corroded.
• Reassemble any components that were removed during inspection.

5. Key Fob Battery Replacement

• Open the key fob using a small flathead screwdriver.
• Remove the old battery and install a new CR2032 battery (or as specified).
• Reassemble the key fob and test its operation.
