The key remote for my car suddenly stopped working, why did this happen and what should I do?

There are a number of reasons this could happen:



  • Could be that the battery died



  • Make sure you know the kind of battery required for your key fob (occasionally it will be engraved on the back. If not, call your dealer or do some research: Make, Model and year.
  • You can likely slide the back off, exposing the battery.
  • Simply replace the old battery with a new one (If you aren’t comfortable doing this without assistance, a youtube video might become your best friend).


  1. Could be water damage


  • In this care it will likely need to be replaced.
  • Never let a child suck on your keys, especially with a remote! (It happens more often than you’d think)


  1. Could be that your key was accidentally placed in Valet Mode


  • If this is the case, you can look on the backside of your remote, and you’ll see a code that explains how to exit this mode (usually Lock+trunk for 20 seconds)



  • Could be that the car was placed in second car mode



  • This happens when a series of numbers is pressed in the correct order to activate second car mode. When a car is in second car mode, it’s because your remote key controls two vehicles.
  • Second car mode simply means that vehicle #1 has been deactivated. If this is the case, you can call your dealer, or read your car manual on how to deactivate the setting.

Why do I need to provide my license if I choose to utilize an online service?


With online services they ask for both license and registration information in order to verify that you are the owner of the vehicle. You should expect to present this information to a locksmith or dealership as well.
