The car key battery is an essential part of your key and in how it works. Without the battery, you can expect problems with your key. Car key batteries are found in most modern car keys because of the convenience and safety features they provide. Like all batteries, your car key battery will need to be replaced eventually. 

Not all car key batteries are made equally, so that may be sooner rather than later. We will tell you how you can replace your car key battery, the types of keys that need batteries, and when the right time is to replace them.

Types of Car Keys

There are many different types of car keys. With each make and model, it seems a new type of key is introduced. That said, all modern keys require a car key battery. Car key batteries were introduced with the transponder key. Transponder keys are the most common type of car keys today. They were initially introduced in the 80s but grew in popularity in the 90s and 2000s.

Transponder keys were introduced to reduce the number of car thefts. They use a chip that sends a code to the receiver of the vehicle. When you insert the key into the ignition, the key sends the code. When the match is confirmed, the car removes the ignition lock, and the key can turn. All of this happens in seconds and is how most modern vehicle keys and ignitions work. To send the signal, the chip in the key requires a battery.

You can find a car key battery in the following keys:

  • Transponder keys
  • Chip keys
  • Smart keys
  • Remote head keys
  • Switchblade keys
  • Key fobs

If you have any of the keys above, you will need a battery. Here is how you know you need a new battery.

Car Key Battery Replacement

You are in need of a car key battery replacement if your car key is experiencing any issues. One of the most common signs you can expect is your car key not working. You go to turn the key of the ignition, but nothing happens. When the signal doesn’t get sent to the vehicle’s receiver, the ignition lock stays, and the key won’t turn. 

Other common signs of your car key battery needing replaced are usually associated with your car key fob. Fobs are often paired with transponder keys and feature lock buttons, a panic button, and a trunk button. Some fobs may also feature a remote starter which will require a battery.

Signs of your car fob battery dying include the following:

  • Decreased signal range
  • Needing to click more than once for a response
  • Delayed lock or unlocking of the vehicle
  • Delayed start of the vehicle for remote starters

If you experience any of the issues above, you should have your car key battery replaced as soon as possible. By having your car key replaced sooner rather than later, you can save yourself from inconvenience later.
