This can prevent your vehicle from starting, and will require a professional to fix the immobiliser system.

Most of the time, a simple replacement is all that is required to revive an old battery and get it working again. A good quality coin-style battery can be purchased at your local hardware store or even some general retailers for between $5-10.

Then, insert the tip of a flathead screwdriver or coin into the slot, and then move it around the edges. Then, insert the new battery and snap the two halves of the fob together. When you're done, you can recycle the old battery at a nearby battery collection site.

If the new battery doesn't solve the issue, it may be a problem with the RFID system on the key fob itself. In most vehicles that feature ignition that is push-button, the fob must be placed close to the ignition barrel to confirm its existence. If the RFID on the key fob does not communicate with the vehicle, you will have to get a new key made or take it to a dealership to fix the immobiliser.

This is why it is important to keep your key fob and key chain safe from a variety of contaminants and water as much as possible.

It's also important to note that a transponder is specifically programmed for a specific vehicle, and altering any of the parts that are sensitive could result in compatibility issues that can affect the functionality of the key.
