What Are the Reasons Why the Key Cannot Open the Trunk?
2 Answers
If the car key cannot open the trunk, it may be due to something stuck in the latch slot when closing the trunk, or it could be due to insufficient power in the remote, resulting in a weak signal that the receiver cannot detect. Additional Information: Smart Key: The car smart key is a common keyless entry system, also known as the smart key system. It consists of a transmitter, a remote central lock control module, and a driving authorization system control module—three receivers and related wiring harnesses that form the control system. Manual Unlocking: There is a button near the driver's seat that can mechanically open the trunk. If that doesn't work, you can check the trunk's condition through the emergency escape passage in the rear seat. If the lock is just tangled with debris, you can remove it yourself. If there is no obvious external obstruction preventing unlocking, it is recommended to visit a repair shop for professional assistance.
I was in a hurry to leave that day and couldn't open the trunk with my key no matter what I did, which was really frustrating. After trying for a while, I realized the most common issue is a dead battery in the remote key, especially for older batteries over a year old that tend to fail in cold temperatures. Simply replacing it with a CR2032 is a low-cost and convenient fix. Another possibility is that the keyhole might be dirty from dust or rainwater, and a bit of lubricant spray can solve the sticking issue. Sometimes, the trunk lock mechanism ages and breaks, or a fuse in the driver's side fuse box blows, causing electronic functions to fail. I remember one time I forgot to disable the anti-theft system, and the trunk was locked tight. It's a good idea to regularly check the key battery and clean the keyhole during maintenance to avoid a lot of trouble. When problems arise, don't panic—try using a spare key or operating closer to the car, as most issues can be resolved on your own.
