Can a Broken Car Key Be Repaired?

[DiManuel]

For car keys, if they are damaged, they can be replaced but not repaired, as the internal lock cylinder cannot be fixed. Below are the functions of a car key: 1. Vehicle Locator: The vehicle locator function uses the remote or alarm system. Pressing the button will make the car's horn sound and the hazard lights flash, helping you quickly find your car in crowded parking areas. 2. Window Closure: After exiting the car, holding down the lock button can remotely close all four windows—a highly convenient and frequently used feature. 3. Open Trunk: The remote key has a trunk release button. If you're coming out of a supermarket with bags in hand, have you ever tried holding down the trunk unlock button (or pressing it twice for some models)? The trunk will pop open automatically!
