Dead Batteries
A dead battery is among the most frequently cited causes of key fob issues. Problems with batteries can be caused by prolonged use or harsh environmental conditions, or ageing. When a battery is damaged it will not supply the power needed to operate the key fob and send the signal needed by the immobiliser system. This could stop the car from starting, resulting in the requirement for a professional to perform an repair to the immobiliser system.
Most times, a simple replacement is all that is required to revive a dead battery and get it working again. A good quality coin-style battery can be found at your local hardware store or at some general retailers for between $5-10. Once you've purchased a new battery, remove the old one from the fob, and carefully open the case. You'll find an opening or notch on the seam separating the top and bottom halves.

Once you are done you can reuse your old battery at a collection site near you.
If the new battery doesn't solve the issue, it could be a problem 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 ignition barrel in order to verify 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 will need to have a new key made or take it to a dealership to repair the immobiliser.

Key for transponder not working
A faulty transponder key is an unfortunate occurrence that can result in serious consequences. Contrary to traditional keys made of metal that simply mechanically activate the ignition the transponder key is equipped with an electronic microchip that sends a unique code to the car's immobilizer system, which confirms its identity before being able to start the engine. This provides an additional layer of security, decreasing the possibility of thefts as well as other vehicle-related crimes. Transponder keys, just like any other electronic device, are vulnerable to various issues, including those relating to the chip's function.
Transponder chips can be delicate and even a minor physical damage can impact their capability to function. It's vital to inspect your transponder keys for signs of wear, as they could be the reason for an immobiliser malfunction.
In addition, the internal microchip in the transponder key is sensitive to water and other environmental conditions, which may hinder its ability to communicate correctly with the immobilizer system of a vehicle. Therefore, it is important to keep the key fob and keychain as far from water as is possible.
It's important to remember that the transponder car key is programmed specifically for a specific vehicle. Making any changes to the sensitive parts could cause compatibility issues that could compromise its function.

Faulty Receiver or Antenna
The transponder chip inside the key of your car transmits an electrical signal to the ECU that lets it determine whether or not the key is the correct one to start the car. broken car key repair stops the engine from starting when it's not the right key. This is to deter thieves from using stolen or duplicate keys to gain access to your car's motor.

Radio frequency interference is caused by heavy electrical equipment, lighting systems, computers, digital devices as well as cable television systems and transmitters. The coaxial antenna cable might have been damaged or cut off. This can happen if your pets run around in the house, or if the cable is damaged during installation.
The receiver might be too far from the antenna. Connect the receiver to another antenna and then check. If the error message persists it is possible that you require a new antenna or reroute your coaxial cable.
Antennas don't really go bad, but they can get pinched or twisted, or loose from the connector, which could cause the RF level to drop. Make sure there's nothing between the receiver and antenna such as a surge protector, splitter or splitter that could impact the signal strength.
If the EEPROM programming method is employed to program a new car key, it will require extracting specific components from your car (security components) and reading the "password" and stored data from them. This requires a great deal of expertise, as there is a risk that the data could be damaged. A professional auto locksmith will minimise the risk by reading information directly from the module using a special tool.
Faulty Electronics
Many modern vehicles are equipped with security systems that stop the engine from starting if the car fob or key aren't present. These systems make use of transponder chips, RFID (Radio-Frequency Identification) technology or immobiliser control units to authenticate the keys or fob when it's inserted into the ignition. It's an effective way to reduce vehicle crime, but it can also be a problem.

If you're experiencing this issue Follow the manufacturer's guidelines to perform a reset of the system, or contact a professional mechanic for assistance.
When you insert the transponder chip into your key, it transmits a code to your immobiliser in the car which is then compared to codes that are stored in the computer. If the codes are the identical, the engine will start and the immobiliser shuts off. If the immobiliser doesn't detect the signal, it'll stop the engine from turning over and may leave you stranded in a remote place.
There are a myriad of issues that can cause the immobiliser in your car to stop working correctly, but the majority of them are fairly simple and inexpensive to fix. The most common cause is a dead or dying key fob battery, which can be quickly identified by a quick diagnostic test.
