What to Do When the Trunk of an Old Passat Won't Open?
2 Answers
If you have been using the remote control to open the trunk lid, it might be due to dirt or rust in the lock cylinder. Spraying rust remover into the lock cylinder a few times should help open it. If you haven't used the remote key to unlock it, it can be difficult to open. Before attempting to open it, it's best to press the unlock button on the key or check if the key battery is dead.
I've encountered the issue of the old Passat's trunk not opening many times. The simplest solution is to try using the mechanical key—the keyhole is usually hidden under the rear emblem or next to the license plate light. When turning the key, don't be too gentle, as the lock cylinder in older cars tends to get stuck. If the electric remote fails, it's likely that the key battery is dead; just replace the battery and press the unlock button to re-sync. Humid weather can also cause the trunk's rubber seal and lock mechanism to stick together—a few firm punches near the lock area often pop it open. If it still won't budge, avoid forcing it, as plastic parts in older cars are brittle. Instead, fold down the rear seats and climb into the trunk; there's an emergency release cord on the right-side interior panel—pull it hard to unlock. Oh, and remember to spray some WD-40 on the lock mechanism periodically to prevent rust.
