Car Immobiliser Repair
In the latter half of the 20th century, automakers began to use immobilisers for cars because hot-wiring was becoming more popular with thieves. The immobiliser blocks the engine of your car from running in the event that the chip inside your key fob is damaged or doesn't match.

Dead Batteries
Key fob problems are typically caused by the battery being dead. Batteries can fail through long-term use, exposure to harsh environmental conditions or simply ageing. When a battery is damaged, it will no longer provide the power required to control the key fob and transmit the signal needed by the immobiliser system. This could stop your vehicle from starting and may need a professional repair the immobiliser system.

Most vehicles that have the push-button ignition feature require the fob to be placed close to the ignition barrel to confirm its presence and send the proper signal for the vehicle to start. If the RFID inside the key fob is not able to communicate with the vehicle, you'll need to have a new key made or take it to a dealer to repair the immobiliser.

Faulty Transponder Key
A transponder key that is faulty can have serious consequences. In contrast to traditional keys made of metal, which merely mechanically engage the ignition, a transponder key is equipped with an electronic microchip that transmits an individual code to the vehicle's immobilizer system to verify its identity before being able to start the engine. This adds an additional layer of security that significantly reduces the chance of theft and other types of vehicle crime. Transponder keys, like any other electronic device, are susceptible to various issues, including those relating to the function of the chip.
