Having the convenience of on-site transponder key reprogramming can be a major benefit for any vehicle owner. Transponder keys are special types of keys that contain chips which must interact with the car’s engine control unit (ECU) in order for the car to start. In the past, if you needed to have transponder key reprogramming done, you had to take your car to the manufacturer and pay hefty fees for the service. Nowadays, however, advances in technology have made it possible for your local locksmith to provide on-site transponder key reprogramming services at far more reasonable costs.
What Is An Immobilizer?
An immobilizer is an electronic device fitted into a car that prevents its engine from running until it receives the correct signal from an accompanying transponder chip within the key. This technology has been mandated by government legislation and automobile manufacturers since the mid-1990s in order to prevent unauthorized ‘hot wiring’ of vehicles – such as is often seen in films and TV shows.
How Does An Immobilizer Work?
When you turn your car’s key in its ignition, its ECU sends a serial number signal to your transponder chip. If this is received correctly, then it allows your car’s engine to start up; if not then it will stay off no matter how many times you try turning the key again.
Why Do You Need Transponder Key Reprogramming?
If your keys are stolen or go missing, first report it at your local police station and then call up an experienced locksmith right away. They can come out to you on site, whether it be at home or work or even stranded in a mall parking lot – and reprogram the chip within other keys so that they send out signals that are recognized by your ECU and allow you to get back on the road safely without fear of theft.
The advantages of having an immobilizer system fitted with a re programmable transponder chip cannot be overstated; it provides extra peace of mind while driving knowing that only those with approved access will be able to use their cars – once they’ve gone through the necessary process via their local locksmith specialist!
