Car immobilisers became a requirement for automakers at the end of the 20th century because hot-wiring cars was becoming more popular among thieves. The immobiliser stops your car from starting if the key fob chip is damaged or doesn't match.

If a battery fails, it can no longer transmit the signal required by the immobiliser, and operate the key fob. This can stop your vehicle from starting, and will require a professional to fix the immobiliser system.

Most of the time replacing the battery is all you need to revive an old battery and make it functional again. You can buy a high quality coin-styled battery at your local hardware store, or even from some general retailers, for $5-10. After you've bought a new battery, take the old one from the fob, and carefully open the case. Find an opening or notch along the line that divides the bottom and top halves of the fob. Push the tip of a flathead screwdriver or coin into the slot, and then move it around the edges. Then, you can insert the new batteries and snap the two halves together. After you've completed the process, you can recycle the old battery at a nearby battery collection site.

If the new battery does not solve the issue, it may be an issue with the RFID system in the key fob itself. Most vehicles that have a push-button ignition design require that the fob be positioned close to the barrel of ignition to verify its presence and send the proper signal for the vehicle to start. If the RFID in the remote key fob repairs fob is not able to communicate with the vehicle, you'll have to get a new key made or take it to a dealership to fix the immobiliser.

Since your key fob likely is frequently tossed around as you use it, it's not unusual for some of the buttons to become misaligned or stuck in time.

Faulty Transponder Key

A transponder key that is defective can have serious consequences. Transponder keys differ from conventional keys made of metal, which engage the ignition mechanically. They have an electronic microchip which sends an unique number to the immobilizer system of the vehicle to verify its identity. This adds a layer of security that significantly reduces the risk of theft as well as other types of crime committed by vehicles. Transponder keys, like any electronic device, are susceptible to various problems that are related to the chip's function.

Transponder chips can be delicate and even a minor physical injury can affect their capability to function. It's vital to inspect your transponder keys for signs that indicate wear, as they could be the cause of a malfunctioning immobiliser.

The microchip in the internal circuit of transponders is also sensitive to humidity and other environmental conditions. This can affect the ability of the key to communicate with an immobilizer system. It's therefore important to keep the key fob and the keychain as far away from water as possible.

It's also important to keep in mind that a transponder key is specifically programmed for a specific vehicle, and modifying any part that is sensitive can result in issues with compatibility that could impact its function. It is best to avoid making any modifications to a key unless you are equipped with the appropriate knowledge and equipment.

A professional locksmith can assist you if your key needs to be replaced or repaired.

This isn't as easy as copying a normal car remote key fob repair key made of metal, and it requires the use of specialized tools to ensure that the right information is entered into the software.

A faulty Receiver or Antenna

The transponder chip inside your car key transmits an electronic signal that is interpreted by the ECU to ensure that it's the right key to start the vehicle. If it's not, the immobiliser system will prevent the engine from being started. This is to deter thieves from using stolen or duplicate keys to gain access to your car's motor.

The receiver could be too far away from the antenna. Connect the receiver to another antenna and test. If the error message continues, you may require an additional antenna or change the route of your coaxial cable.

Antennas do not really fail however they could be twisted or pinched or even loosen from the connector, which may cause the RF level to decrease. Make sure there's nothing between the receiver and antenna such as a surge protector, splitter or splitter, that 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 vehicle (security components) and reading the "password" and stored information from them. This requires a lot of knowledge, as there is a risk that the data may be corrupted. A professional auto locksmith has a deep understanding of the circuit board and can reduce the chance of this happening by reading the data directly from the module using a specific tool.
