6 Reasons Why Your Remote Car Key Stopped Working and What to Do About It

by | May 23, 2022 | Locksmith

It’s a frustrating experience when your car key fob stops working. Suddenly you can’t get into your car or start the engine. There are several reasons why this might happen, but don’t worry – we’re here to help. In this blog post, we’ll outline five of the most common causes of remote car key failure, and what you can do about it. Stay calm and read on for advice on how to get back on the road as quickly as possible!

These are the Top 6 Reasons Why Your Remote Car Key Stopped Working

  1. Dead batteries: This is the most common reason for car key failure. If your key fob isn’t working, check the batteries and replace them if necessary. You can easily open the key fob to access the batteries. When in doubt check for your car owner’s manual or a Youtube guide.
  2. Dirty or damaged buttons: If your button is not responding properly, it might be because it’s dirty or damaged. Cleaning the button with a soft cloth can sometimes solve the problem. If that doesn’t work, you might need to replace the button. This is where you may want to consider asking a local locksmith for help.
  3. Worn-out key: Over time, your car key will wear out from normal use. This can cause the button to become less responsive. If this is the case, you’ll need to get a replacement key from your dealership or local locksmith.
  4. Damaged transponder: If you have a remote key with a transponder, it may be damaged and need to be replaced. Transponders are tiny chips that transmit a signal to the car’s ignition system. They can be easily damaged if dropped or exposed, this will definitely require the expertise of a professional locksmith.
  5. Faulty immobilizer: If your car’s immobilizer is not working properly, it can prevent your car key from starting the engine. You’ll need to get this fixed by a qualified mechanic.
  6. Damaged car key: If your car key is damaged, it will likely need to be replaced. This is something you should be able to do at a local car dealership or locksmith.
