I don't know how to program a new key transponder

The new keys contain a transponder that will need programming, though some keys can be taken apart and the transponders transferred to the new key. The transponders I have seen are about the size and shape of a grain of short rice.

1 First you will need to purchase a blank Toyota transponder key. You can do this from the dealership, a locksmith, or an online source such as eBay. Once you have the key, take the blank key and the master key to a locksmith that he or she can duplicate the key. This will be much cheaper than the dealership.

2 Now that you have the newly cut key and the master key, you can program the Toyota transponder key. Sit in the driver's side of the Toyota vehicle. Press and release the brake and gas pedal simultaneously.

3 Insert the master transponder key. Do not turn it. Push and release the gas pedal 5 times within at least 15 seconds of inserting the master key.

4 Press and release the brake pedal 6 times within 20 seconds of completing step 3, then remove the master transponder key.

5 Insert the newly cut transponder key into the ignition, but do not turn. Press the gas pedal once.

6 Wait up to 2 minutes or whenever the security light on the dashboard turns off. Once the light goes off, remove the new transponder key and press the brake pedal once. The new transponder key should now be programmed. Test the key by attempting to start the engine. If the engine does not start, repeat the steps above.

You will have to program you keys to the immobiliser in the car. The keys transmit a code to the immobiliser in the car and if you have fitted anew ignition switch you will have new keys with the wrong transponder. You may be able to fix it by replacing the new transponder in the new key with the old transponder out of the old key

These vehicles use Fords Securilock transponder system to prevent vehicle theft. Basically, there is a little radio chip in the key that transmits a code to the computer when you start the car. If this code doesn't match the computer, the computer disables fuel and spark so the engine won't run. If you have a spare key, try that to see if it works. If it doesn't work, then the Securilock system needs service. Unfortunately only the dealer can service this system because it is integrated into the vehicle computer.

If your spare key works, then the key you tried to use has a damaged transponder and the key needs to be replaced. If you don't have a spare key, contact a locksmith and have them make you a new key. I have to warn you, transponder keys are not cheap. They can cost easily $75 and some even go for $150. But, that is probably cheaper then having Ford make one and even if the spare doesn't work, when you get the system fixed by the dealer they can program your spare key as well so you don't waste the money on the key.

the taurus is equipped with a pats key system that has a key that communicated to the anti theft transponder. if the transponder, which is mounted around the ignition lock cylinder was damaged a it will need a new tranponder and a new set of keys . you will however need the dealer to program the keys. if you have tow keys now you might try getting those programmed first. if that does not work it will need a transponder nad keys and even possably a pcm

This means that the programming of the Transponder Key has been corrupted or the Programming data of the Key in ECU ( Electric Control Unit ) has been lost or not responding. You now have to get a new Transponder Key. You can get it on E-bay for $30. After you receive it, reprogram the car to the New Transponder Key to the ECU ( the process in usually given in the instruction manual or in the Service Manual ). Then the car will start perfectly.
