How to Program a Car Key Without the Original?

A transponder key, also known as a chipped key, is a device designed to transmit a low-level signal from a handheld device to a remote receiver. This key is equipped with a microchip inside its plastic head. The microchip will give off a signal to communicate with the receiver in your car using radio frequency identification technology to activate your car's ignition system. In other words, the microchip transmits a specific alpha-numeric code to your ignition to start your car. If the signal does not match the signal coded into your remote receiver, your car won't start. A vehicle that uses a transponder key will not function without the original programmed transponder key.

If you've lost the original transponder key, you may be wondering how to program a transponder key without the original. Some car owners think that it's impossible to replace a transponder key without having access to the original. However, that is not correct. If you're looking to program a transponder key but don't have the original key, this guide will explain how to get through the process.

  • Step 1: Sit in the driver's seat and insert the transponder key into the ignition and turn it to the "ON" position. Leave the key in this position for about 10 minutes and 30 seconds. Your vehicle's security light should come on.
  • Step 2: After completing the first step and the security light has come on, wait for 15 minutes. Set a timer so that you observe the timing correctly.
  • Step 3: After the 15 minutes have elapsed, the security light should go off. Within three minutes of the lights going out, turn off the ignition and then turn the key to the "ON" position. Again, the security light should come on and remain on for 15 minutes. The security light will go off again after 15 minutes have elapsed.
  • Step 4: Repeat the same actions as in step 3. Specifically, turn the transponder key to the "OFF" position and put it back to the "ON" position. The light should come on again, and you need to wait for 15 minutes. When the security light turns off this time, the whole process should have taken about 45 minutes, and your new transponder key will be generated.
  • Step 5: Use the transponder key to turn the ignition on and start the car to confirm if the key is working properly. The original key will no longer work on your vehicle.

If you're unable to program your transponder key after following these steps a couple of times, call a trusted locksmith to help you program your transponder key.
