Can a Broken Car Key Be Repaired?
3 Answers
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!
I often help friends repair car keys. It's true that a broken car key can be repaired, but it depends on the type and extent of the damage. If it's a regular mechanical key that's cracked or bent, many auto repair shops or professional locksmiths can weld and fix it, and the cost is affordable, usually ranging from tens to a hundred yuan. If it's a smart key with a broken shell or malfunctioning buttons, as long as the internal circuit board isn't damaged, you can replace the shell or reprogram it to reactivate it, though the cost might be higher, around a few hundred yuan. Before getting it repaired, it's advisable to test it yourself: try inserting it into the car door or starting the car to see if it functions properly. If it doesn't work, quickly take it to a 4S shop or locksmith for diagnosis—don't try to open it yourself to avoid making it worse. Preventive measures include handling the key carefully, not placing it in high places, or buying a protective case to reduce the risk of damage from drops.
The other day I accidentally dropped my car key on the ground, cracking the casing. I was so anxious I kept pulling my hair. Tried gluing it but didn't work, and was afraid of damaging more components. Later went to a local repair shop where the mechanic checked and said the internals were fine, just replaced the outer shell for 80 yuan. Saved a ton of money since a new OEM key would cost thousands. So damaged keys can be repaired, but depends on luck - if the circuit board breaks then it's irreparable. Advice: don't panic if you drop it, first test functionality, if not working then seek professional help instead of DIY like me. Using a key pouch for drop protection helps prolong its lifespan.
