Can You Drive With A Dead Key Fob

Audi Key Fob battery change – (US) Key battery DIY

No auto manufacturer is going to pin everything on the key fob working all the time. Therefore, even if your battery dies, you can still use the fob to drive the car.

  • Despite most cars going keyless, several of them still have a key slot usually located on the steering column. It will typically be covered by a plastic cover which you can pop off. Once you insert the physical key into it, you can easily turn on the car and drive away.
  • Some cars begin ignition with the START button, which switches on the car only if the key is detected. With a dead battery, the car may not recognize the key fob and hence the START button may be unresponsive. In such cases, you can use the fob itself to push the START button, which will switch on the car.
  • Some vehicles like Fords have a slot on the steering column where you can insert the fob, which will start the vehicle.

    The Audi key fob will grant anyone holding it access to the car conveniently, so anyone without it wont be allowed into the car unless they forced themselves in but the car still wont start until the car fob grants access.

    Checking The Battery Life

    The first thing to check when your key fob fails to operate is the battery. Many fobs have a little LED light that will illuminate when you press the fob buttons. If the LED light does not illuminate, the battery inside is dead or has some other issue. Check the voltage of the battery. If it is less than 3 Volts, the fob is probably too weak to work.

    Most fobs can be pried open to access the battery. Check the voltage to determine if it is low or if it is completely dead. When the voltage is too low, a warning light will appear. Replace the battery as soon as possible. Make sure to buy the correct type of battery. Incorrect types of batteries will not work correctly. You can find replacement batteries online or in your owners manual.
