2 Answers
Locate the fuel tank cap switch under the driver's seat, pull up the fuel tank cap switch, and the fuel tank cap will pop open automatically. Unscrew the fuel tank cap lock cylinder counterclockwise and remove the unscrewed lock cylinder. Screw the new lock cylinder clockwise, then secure the cover plate in place.
Last time I repaired my car, I found the fuel tank cap lock cylinder was broken, and it took me quite a while to replace it. First, you need to find the specific lock cylinder for your car model, which can be purchased online or at auto parts stores. Before removing the old lock cylinder, you must unscrew the bolts inside the fuel tank cap—some cars hide them under the rubber seal. Remember the disassembly sequence, especially not to lose the spring and small clips. When installing the new lock cylinder, press down the spring and slowly push it in until you hear a click, indicating it's properly seated. Finally, screw the bolts back and test the cap by opening and closing it a dozen times to ensure it doesn't jam. It's advisable to keep some lubricant grease handy to apply on the lock cylinder to prevent it from freezing in winter. The most troublesome part of the whole process is handling the small parts, so those with larger hands might want to ask family members for help.
