How to Start the Car When the Key Fob is Broken?

There is a metal key blade on the remote key fob. There is a switch on the remote key fob; the key blade can be directly inserted into the door's keyhole to open the car door. Place the remote key fob against the push-to-start button, hold it for a moment, and the car can be started (this method works for most cars).
I've experienced car key failures preventing vehicle startup several times, which is quite common. If the electronic component of the key malfunctions (e.g., dead battery or sensor failure), most modern vehicles have contingency measures: First check if the key fob contains a small metal piece or mechanical key portion to unlock the door. Once inside, for keyless ignition systems, try placing the key near the start button or in designated induction zones like under the center armrest - some models require holding it against steering column sensor icons. Pressing the ignition button might then work. For completely broken or lost keys, immediately use the spare; I recommend keeping a backup set in your wallet or at home. Avoid forced entry or push-starting as last resorts - automatic transmissions could sustain damage, compounding problems. The safest approach is parking securely, then calling roadside assistance or visiting a locksmith/mechanic for key replacement, battery changes, or reprogramming new keys.
My car key has also been problematic recently, causing headaches during startup. The key is not to panic; first, check the key structure: if there's a mechanical backup part, use it to open the door. For smart key malfunctions, try placing the key close to the car's startup area—my car requires placing the key in the cup holder to start. A spare key is the first choice for emergencies; always remember to carry it with you. If you don't have a spare, immediately contact friends or family to bring one or arrange a ride to fetch it—don't delay. In case of electronic failure, also check if the key battery is depleted; replacing it is simple and straightforward. Avoid attempting to push-start the car or short-circuiting with wires, as these methods are high-risk, especially with electric vehicles that may pose an electric shock hazard. Afterward, it's best to visit a professional shop for a check-up to prevent recurrence. Develop a habit of testing the key's functionality once a month to prevent issues before they arise.
If the car key is broken and you need to start the car, follow these steps each time. First, use the mechanical key blade to open the door and enter the car. For keyless start vehicles, place the broken key near the steering wheel's induction point or under the central button to attempt ignition. Immediately retrieve and use the spare key if available. If not, call for roadside assistance or towing services right away—do not risk attempting repairs yourself. To prevent accidents, park the car in a safe location by the roadside. Afterwards, take the key to a 4S shop or locksmith for repair or replacement; replacing it usually takes just a few minutes. Always keep your spare set well-maintained to avoid emergencies.
