Why Does My Key Fob Not Work After Replacing Car Battery?

If you’ve recently replaced your 12V car battery and found that your key fob no longer works, you’re not alone. This is a common problem that can be caused by a few different things. One possibility is that the new battery is not properly connected.

FAQs

Why Did My Key Fob Stop Working All of a Sudden?

If your key fob suddenly stops working, there are a few potential reasons why. Here are some of the most common:

The Batteries May Be Dead

Key fobs use small coin-sized batteries that can die without warning. If your key fob isn’t working, try replacing the batteries first.

The Key Fob Could Be Damaged or Defective

If the batteries aren’t the problem, then it’s possible that the key fob itself is damaged or defective in some way. This is usually not covered by warranty, so you’ll likely have to buy a new one if this is the case.

The Car’s Receiver Could Be Damaged or Defective

In rare cases, it’s possible that the receiver in your car (the part that actually communicates with the key fob) is damaged or defective. This will require a trip to the dealership or mechanic to get fixed and is usually not covered by warranty either.

There May Be Interference From Other Electronic Devices Nearby

RFID signals can sometimes be disrupted by other electronic devices nearby, causing your key fob to stop working properly.

Do Key Fob Need Reprogram After Changing the Battery?

Yes, if you change the battery in your key fob, you will need to reprogram it. This is because the key fob sends a signal to the car that tells it what the code is for that specific key. If you change the battery, that code will no longer be valid and the car will not start.

Can You Drive With a Dead Key Fob?

If your car key fob dies, you will not be able to start your car. The key fob is the device that sends a signal to the car’s computer, telling it to start the engine. Without a working key fob, you will not be able to start your car.

You can, however, still, use your physical key to unlock the door and enter the vehicle. Once inside, you can manually override the electronic ignition by inserting the key into the ignition and turning it. This should work on most cars built after 1990.

If it doesn’t work on yours, consult your owner’s manual for further instructions.

Conclusion

If your key fob isn’t working, there are a few things you can do to try and fix the issue. First, check the battery to see if it needs to be replaced. If the battery is fine, then you can try resetting the key fob by holding down the button for 20 seconds.

If neither of those solutions works, then you may need to contact a locksmith or dealer to get a new key fob.
