If you want to save money by programming your own key instead of paying the dealer hundreds of dollars, you can. Some Ford vehicles require a transponder key to start the vehicle. Without the chip in the key, the car will not start. Follow these steps to program your own chip key for just a few dollars.
First of all this only works with Ford or Mazda cars and trucks. There is a different procedure for other makes and models. You will first need to purchase a transponder chip key. You can either order one off of eBay or you can buy one from the dealership. A local locksmith may also be able to provide you with one. The last resort should be the dealership, they will charge you an arm and a leg.
Next you will need to have the transponder key cut like the original. Ask a local locksmith to do this. Their charges will be minimal. Probably less than $10.
