Car Immobiliser Repair
Car immobilisers became a necessity for automakers in the latter part of the 20th century, as hot-wiring cars became increasingly popular with thieves. The immobiliser stops the engine of your car from starting in the event that the chip inside your key fob is damaged or does not match.
It is therefore important to fix your car's key immobiliser as soon as it becomes faulty or damaged. Here are a few most frequent reasons for the immobiliser of your car not working:
Dead Batteries
A dead battery is among the most frequent causes of key fob issues. A battery can go bad from long-term use or exposure to harsh environmental conditions, or simply ageing. When a battery fails to function, it is unable to transmit the signal required by the immobiliser and operate the key fob. This could stop the car from starting, which results in the requirement for a professional to perform an repair of the immobiliser system.
Most of the time an easy replacement is all that is required to revive the battery that has died and make it functional again. You can purchase a good quality coin-styled battery at your local hardware store or even from some general retailers for around $5-10. After purchasing the latest coin-style battery carefully take the old one off and open the casing. Look for an opening or notch along the line that divides the top and bottom halves of the fob. Push the end of a coin or flathead screwdriver into the slot and then work around the edges to pop open the fob. Then, you can insert the new batteries and then snap the two halves together. Once you are done, you can recycle the old battery at a battery collection center close to you.
If the new battery doesn't fix the problem, there may be an issue with the RFID system within the key fob. The majority of vehicles with an ignition system that uses a push button require that the fob be placed close to the barrel of ignition in order to verify its presence and send the right signal to allow the vehicle to start. If the RFID inside your key fob isn't in a position to communicate with your vehicle, you'll need to make a key for your vehicle or take it to a dealer for an immobiliser repair.

This adds a layer of security that reduces the risk of theft as well as other types of crime committed by vehicles. Transponder keys, just like any other electronic device, are prone to a variety of issues, including those relating to the chip's function.

Receivers or Antennas that are not working properly
The transponder chip in your car key sends an electronic signal that is interpreted by the ECU to confirm that it's the right key to start the vehicle. If it isn't, the immobiliser system will stop the engine from being started. This is a way to prevent thieves from using stolen or duplicate keys to gain access to your car's motor.
