Dead Batteries
Key fob issues are usually caused by the battery being dead. Battery problems can be caused by prolonged use or harsh environmental conditions, or ageing. When a battery is damaged, it will no longer provide the power required to operate the key fob and transmit the signal needed by the immobiliser system. This could prevent the vehicle from starting, resulting in the need for a professional to carry out an repair to the immobiliser system.
Most of the time an easy replacement is all that is needed to revive the battery that has died and get it back to working. You can buy a high quality coin-styled batteries at your local hardware store or even from general retailers, for $5-10. After purchasing the new battery, carefully remove the old one and open the case. Look for an opening or notch along the edge that separates the top and bottom halves of the fob. Then, insert the end of a coin or flathead screwdriver into the slot and work it around the edges to open the fob. Then, you can insert the new battery and snap the two halves of the fob together. Once you are done recycling your old battery at a battery collection facility close to you.
If the new battery doesn't fix the problem it could be an issue with the RFID system on the key fob itself. In most vehicles with push-button ignition, the key fob is required to be positioned close to the ignition barrel to confirm its presence. If the RFID on the key fob does not communicate with the vehicle, you'll have to get a new key made or take it to a dealership to repair the immobiliser.
If replacing the battery doesn't solve the issue it's worth disassembling the key fob and looking for any buttons that seem to be off-center or damaged. It's common for buttons to become misaligned over time, as your key fob is likely be jostled around a lot.
Faulty transponder key
A transponder key that's not working could have severe consequences. Transponder keys are different from traditional metal keys that engage the ignition mechanically. They feature an electronic microchip that transmits an individual number to the immobilizer system of the car to verify the identity of the key. This adds an additional layer of security that greatly reduces the chance of theft as well as other types of vehicle crime. Transponder keys, as with any electronic device, are vulnerable to various problems related to the chip's purpose.
Transponder chips are delicate and even a tiny amount of physical damage could affect their ability to function. It's vital to inspect your transponder keys to see if there are signs of wear, as these can be the cause of an immobiliser that is not working properly.
In addition the internal microchip inside a transponder key is also sensitive to water and other environmental conditions, which may interfere with its ability to communicate correctly with a vehicle's immobilizer system. This is why it is important to keep your key fob and key chain free from any water or other contaminants as much as is possible.
It's important to remember that transponder keys are programmed specifically for a specific vehicle. Modifying any of the parts that are sensitive could lead to compatibility problems that could compromise its function. It's best to avoid making any modifications to a key unless you're equipped with the appropriate knowledge and equipment.
A professional locksmith can help you if your key requires to be repaired or replaced. They can duplicate your key or design new keys, and program it to match the immobilizer system in your vehicle, making sure it functions in a proper manner. This process isn't as simple as copying a standard car key made of metal, and it requires specialized tools to ensure that the proper information is entered into the software.
Faulty Receiver or Antenna
The transponder chip in your car key sends an electrical signal to the ECU that allows it to determine whether or not it is the right one to start the vehicle. The immobiliser stops the engine from running if it's not the correct key. This is to deter thieves from using stolen or cloned keys to gain access to your car's motor.
However, if the signal fails to reach the ECU due to an issue with the antenna or receiver the car won't start. A professional auto locksmith will be able to help you resolve this issue.
It could result from many factors, such as an incompatible antenna or electrical interference. Radio frequency interference is caused by electrical equipment that is heavy, lighting systems, computers, digital devices as well as cable television systems and transmitters. It's also possible that a coaxial antenna cable is damaged or disconnected. This could happen when pets run around the house or the cable is bent or damaged during installation.
Another reason that the antenna might not be working is that the receiver may be too far from the antenna. You can test this by connecting the receiver to another antenna. If the error message continues it is possible that you need to install a new antenna or reroute your coaxial cable.
Antennas aren't necessarily damaged, but they can get pinched or twisted, or even loosen from the connector, which may cause the RF level to drop. Examine if there's anything between the receiver and antenna such as a surge protector, splitter, or splitter, which could affect the signal strength.
If the EEPROM programming method is employed to program a new car key, it will require extracting specific modules from your car (security components) and reading the "password" and stored information from them. This requires a lot of expertise, as there is a risk that the data may be corrupted. A professional auto locksmith will minimise the chance of this happening by reading data directly from the module with a specific tool.
Faulty Electronics
A lot of modern cars are equipped with security systems that block the engine from beginning if the car's ignition fob or key aren't present. These systems use transponder chips, RFID (Radio-Frequency Identification) technology or immobiliser control units to authenticate the key or fob once it's placed in the ignition. This can be a fantastic way to reduce vehicle theft however, like all pieces of electronic equipment, it's possible to be a bit faulty.
If the security light on your dashboard is lit solid, it means that the car immobiliser hasn't been able to receive the signal from the fob or key. This can be due to a variety of reasons, including an insufficient battery on the keyfob, or physical damage to the key. If you're experiencing this issue, follow the manufacturer's instructions to perform a reset of the system, or call an expert mechanic for assistance.
When you insert the transponder chip in your key, it transmits an encoded code to the immobiliser system in your car that is then compared with the codes that are stored in the computer. If the codes match, same, the engine will turn on and the immobiliser will shut off. If the immobiliser doesn't detect the signal, it'll stop the engine from turning over and may leave you stuck in a secluded location.
A variety of issues can cause the immobiliser in your vehicle to not function properly. However, most of them are easy and cheap to fix. A dead or dying keyfob battery is the most frequent issue, and it can be easily identified by a simple diagnostic test. If this does not resolve the problem, there could be other issues with your car's electrical system that are impacting the immobiliser's performance. If this is the case, a professional can examine the electrical system of your car and look for indications that it could be affected by damaged connections or loose connections.
