How to Start a Hyundai Car When the Key Fob Battery is Dead?
4 Answers
Here are the methods to start a Hyundai car when the key fob battery is dead: 1. You can use the mechanical key to start the car. 2. If the key is a proximity key, after pulling out the mechanical key from the top of the key fob, you will see a keyhole on the door handle. After opening the door, press the proximity key against the push-button start switch to start the vehicle. However, this is only an emergency method. Below is some information about Hyundai cars: Taking the Hyundai Elantra as an example, its body dimensions are 4570mm in length, 1775mm in width, and 1445mm in height, with a wheelbase of 2700mm. Its front face still adopts the typical family design, with fewer sharp lines and more rounded contours, making it look more harmonious and balanced. The grille is fully chrome-plated, giving it a more stylish and upscale appearance.
I also ran into the dead key fob issue last week. I panicked for a moment but then remembered modern Hyundai vehicles have emergency starting methods. First, take out the mechanical key to open the door. After getting in, don't rush to insert the key - my Tucson supports keyless start, so you need to place the dead fob near the small induction area next to the steering wheel (near the cup holders), then press the start button while holding the brake pedal, and the engine fired right up. Afterwards, I immediately went to the supermarket and bought a coin battery to replace it, costing less than ten yuan. I recommend keeping an eye on your key fob's indicator light - when it dims, change the battery promptly to avoid emergencies. Also, never skip the habit of carrying a spare key. Last time, if I hadn't brought an old spare with me, I would've had to call a tow truck.
Don't panic if your Hyundai key fob battery dies. As a long-time Sonata owner, I've dealt with this before. Simply use the mechanical key to unlock the door. Once inside, calmly place the dead key fob against the start button or designated area (like the storage compartment below the infotainment screen - some models have the sensor there). Then press the brake and start button simultaneously - this usually wakes up the system. I've also replaced the battery myself - just pop open the key fob's back cover. CR2032 batteries are widely available. Pro tip: Regularly check your key's performance. Weak signals from an aging key cause slow starts and inconvenience. Keep spare batteries in your car - it's smarter than scrambling for help last-minute.
The keyless start feature in Hyundai cars is quite considerate, allowing the vehicle to start even when the battery is dead. I personally tested it: first, use the manual key to unlock and enter the car, then place the key near the start button, maintain contact for a few seconds, and finally press the brake to start. The whole process takes about ten seconds. Avoid leaving the key randomly in the car, as the signal may be interfered with. If the sensing is poor, try a few more times. Regularly replacing the battery is always a good practice.
