Can the original key still be used after getting a new car key? With the development of automotive manufacturing technology, people are accustomed to collectively referring to the devices that unlock car doors and start the engine as keys. Pure mechanical car keys: Mechanical car locks are the most common and earliest type of car anti-theft locks, rarely used alone in mid-to-high-end cars nowadays. Mechanical locks mainly serve to restrict vehicle operation and provide limited anti-theft assistance, being vulnerable to break-ins. Generally, car thieves can pry open a steering wheel lock in just tens of seconds. Electronic anti-theft lock keys: Electronic anti-theft locks are the most widely used and commonly installed type of anti-theft locks. The primary functions of one-way electronic anti-theft systems include: locking/unlocking car doors, alarm activation upon vibration or unauthorized door opening, etc. Some branded products also offer additional features based on customer needs, such as using an electronic remote control to start or shut off the engine.
I recently got a new key for my car, and whether the original key still works is quite important. Some older car models use traditional mechanical keys, and after getting a new one, the old key can still unlock the door and start the car because the lock cylinder hasn't been changed. But my car is a modern model with a chip. If the old key's code isn't specifically deleted when getting a new one, it might still be able to start the engine—which would be awkward. I'm worried about security risks; if the car gets stolen, it would be a big problem. I suggest you directly ask the dealership or a professional shop. They can help reprogram the keys to completely deactivate the old one. Getting a new key isn't expensive, ranging from 50 to 200 bucks—don't skimp and risk it. Also, when getting a new key, it's best to go in person and supervise to ensure the old key is deleted from the system. Remember, safety first—don't risk driving out with the old key.
