A dead battery in your car key is more common than you think. But what does that actually mean for the operation of your key? Can you still open or start the car?
In this blog, we explain what you can still do with a dead battery, and when to take action.
Keyless entry vs. remote control
Do you have a car key with keyless entry? Then the car can normally detect if the key is nearby. If the battery is dead, it can no longer do so. Yet in many cars, you can still start just by holding the key against the start button.
With a standard key with buttons, opening the car remotely usually no longer works. However, the key blade - the physical metal part of the key - still works in the door lock.
Can you still start with a dead battery?
Yes, in many cases you can. The immobilizer (transponder chip) works independently of the battery. Therefore, the car can still recognize your key, as long as the chip itself is fine.

Some cars require you to hold the key close to the start button or even place it in a special holder. Consult your car's manual if in doubt.

Avoid problems on the road

Would you rather have a completely new key made?
Conclusion
Even with a dead battery, you can still start your car in many cases, but the ease of use disappears. Your remote no longer works, and you have to physically use the key. By replacing your battery in time, you avoid inconvenience and are always ready to drive.
