This can prevent the car from starting, which results in the need for a professional to carry out an repair to the immobiliser system.

In most cases, a simple battery replacement will bring back the battery that was dead. You can purchase a good quality coin-styled battery from your local hardware store or even from general retailers, for $5-10.

When you're done, you can recycle your old battery at a collection center close to you.

If the new battery does not solve the issue, it may be an issue with the RFID system within the key fob. Most vehicles with a push-button ignition design require the fob to be positioned close to the ignition barrel to verify its presence and send the correct signal to allow the vehicle to start. If the RFID on the key fob isn't able to connect with the vehicle, you'll need to make a key for your vehicle or take it to the dealer for an immobiliser repair.

This adds a layer of security, decreasing the risk of thefts and other vehicular crimes. However, as with any other electronic device, transponder keys are susceptible to a myriad of issues which include those that concern the chip's functionality.

Transponder chips can be delicate and even a slight physical damage can impact their capacity to function. It is crucial to examine your transponder keys for signs of wear, as these can be the cause of an immobiliser that is not working properly.

The microchip in the internal circuit of a transponder is also sensitive to moisture and other environmental conditions. This could affect the ability of keys to communicate with an immobilizer system. This is why it's important to keep your key fob and key chain free from a variety of contaminants and water as much as is possible.

It is important to keep in mind that the transponder car key is programmed specifically for a specific vehicle.

This isn't as straightforward as copying a normal metal car key, and it requires the use of specialized tools to ensure that all of the right details are entered into the software.

A faulty Receiver or Antenna

The transponder chip inside your car key transmits an electrical signal to the ECU that allows it to determine whether the key is the right one to start the car. If it's not, the immobiliser system will prevent the engine from being started. This is to stop thieves from accessing your vehicle's engine by using a stolen or copied key.
