Car Immobiliser
repair keys near meIn the late 20th century automakers began using immobilisers for cars because hot-wiring was becoming more popular with thieves. The immobiliser prevents your car's engine from starting when the chip in your key fob is damaged or does not match.
It is crucial to fix your car's key immobiliser immediately if it starts to fail or is damaged. Here are a few most frequent reasons for the immobiliser on your car not working:
Dead Batteries
Key fob issues are usually caused by the battery being dead. A battery can go bad from long-term usage or exposure to harsh environmental conditions, or simply ageing. When a battery fails, it can no longer transmit the signal required by the immobiliser to operate the key fob. This can prevent your vehicle from starting, and will require a professional to fix the immobiliser system.
In the majority of instances, a simple battery replacement will bring back the battery that was dead. A good quality coin-style battery is available at your local hardware store or even at a general retailer for between $5-10. Once you've purchased a new battery, take the old one from the fob, and carefully open the case. Look for slots or notch on the seam that separates the bottom and top halves of the fob. Then, insert the end of a coin or flathead screwdriver into the slot and work around the edges to pop open the fob. Next, insert the new battery and snap the two halves of the fob closed. Once you've finished recycling the old battery at a nearby battery collection site.
If the new battery isn't able to solve the issue it could be a problem with the RFID system in the key fob itself. Most vehicles that have a push-button ignition design require the fob to be positioned close to the ignition barrel to confirm its presence and send the proper signal to allow the vehicle to start. If the RFID in the key fob cannot communicate with the vehicle, you will have to get a new key or take it to a dealership to repair the immobiliser.
If replacing the battery doesn't solve the issue It's worth taking the key fob apart and looking for any buttons that seem off-center or damaged. Since your key fob is constantly tossed around when you use it It's not uncommon for some of the buttons to become misaligned or stuck in time.
Key to the Transponder is not working.
A transponder key that is defective could have severe consequences. Contrary to traditional keys made of metal that mechanically engage the ignition the transponder key is equipped with an electronic microchip that transmits an unique code to the car's immobilizer system, which confirms its identity before being able to start the engine. This adds an extra layer of security, which reduces the risk of thefts and other crimes committed by vehicles. However, just like any other electronic device transponder keys are prone to a myriad of issues, including those related to the functionality of the chip.
Transponder chips are delicate and even a tiny amount of physical damage can affect their ability to function. It is essential to check your transponder keys for signs that indicate wear, since these could be the reason for an immobiliser that is not working properly.
The microchip in the internal circuit of transponders are also sensitive to moisture and other environmental conditions. This can affect the ability of the key to communicate with an immobilizer system. As a result, it's important to keep your key fob and key chain safe from a variety of contaminants and water as much as is possible.
It's also important to keep in mind that a transponder key has been specifically programmed for a specific vehicle, and changing any sensitive parts can lead to compatibility issues that can affect its functionality. It is best to avoid making any modifications to a key unless you're equipped with the appropriate knowledge and equipment.

They can duplicate the key you have already got or design a brand new one from scratch, and they'll be able program it to work with your specific vehicle's immobilizer system, ensuring that it operates properly. This process isn't as simple as copying a regular car key made of metal, and it requires specialized tools to ensure that the correct details are entered into the software.
A faulty Receiver or Antenna
The transponder chip in your
mobile car key repair key transmits a signal that is recognised by the ECU to confirm that it's the correct
key fob repairs to start the car. If it isn't the correct key, the immobiliser system will prevent the engine from being started. This is to stop thieves from using stolen or duplicate keys to gain access to your vehicle's motor.
If the signal isn't received by the ECU because of a problem with the antenna or receiver the car won't start. A professional auto locksmith will assist you in resolving these issues.
It could be due to a variety of reasons, including an incompatible antenna or an electrical interference issue. Radio frequency interference could be caused by heavy electrical equipment lighting systems computers, computers, digital devices cable television systems, and transmitters. The coaxial antenna cable might have been damaged or disconnected. This can occur when pets roam around the house or the cable is bent or damaged during installation.
Another reason why the antenna may not be functioning is that the receiver may be too far from the antenna. Connect the receiver to a different antenna and then check. If the error message is still present it is possible that you require a new antenna or redirect the coaxial cable.
Antennas aren't bad, but can be bent, pinched or detached from their connectors, which can cause the RF level of the signal to drop. It is also important to determine if there is any equipment installed between the antenna and the receiver, such as a surge protector or splitter because this could influence the signal strength.
If you choose to use the EEPROM method to program a car key, you'll need to extract specific modules (security components) from your vehicle and then read the "password" from them. This requires a lot of knowledge, as there is a chance that the data could be corrupted. A professional auto locksmith can minimise the chance of this happening by reading data directly from the module with a special tool.
Faulty Electronics
A lot of modern vehicles have security systems that prevent them from starting the engine in the event that they don't have a remote or key to the car. 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 put into the ignition. It's an effective way to reduce the crime in vehicles, but it can also go wrong.

When you insert your transponder into your key, the chip sends a signal to the immobiliser system in the car. This code is then compared against the codes stored on the computer. If the codes are the same the engine will turn on and the immobiliser shuts off. If the immobiliser fails to detect the signal it won't turn over and you could be stuck.
There are many problems that can cause the car's immobiliser to stop working correctly, but the majority of them are easy and inexpensive to address. The most common culprit is a dying or dead key fob battery which can be identified by a quick diagnostic test.
