What to Do When the Car Remote Has Power but Doesn't Work?
1 Answers
If the car remote has power but doesn't work, the following methods can be used to address the issue: If the interior of the car key is damp or dirty and oxidized, the buttons may gradually become less responsive. Solution: Open the key casing, remove the battery, and use a cotton swab dipped in alcohol to clean the button bases on the internal circuit board. After cleaning, reassemble and test if it works properly. The circuit board inside the car remote may have poor contact, leading to malfunction. Solution: Soldering is required. However, since the solder joints are very small and most car owners lack tools like a soldering iron, it is recommended to take it to a professional electronics repair shop or a mobile phone repair service. Electronic signal interference from devices such as mobile phones or signal blockers (like transformers) in the vicinity of the car owner and vehicle may cause the issue. Solution: The car owner can try standing in a different location first. If that doesn't work, move the vehicle to another spot. The internal wiring of the key is relatively fragile and can easily be damaged by severe impact. Solution: Repair is needed. If water enters the key and damages the internal circuit, it can also cause the remote to malfunction. Solution: Repair or replace the key. Key and car mismatch: Remove the chip from the old key and install it into the new remote key to fully control the car.
