Most people don’t realize that Ford, Mazda and GM transponder keys can be programmed without a scan tool or a trip to the dealer. With Fords and Mazdas you will need to have two keys that are already programmed, GM’s require one key to be already programmed.

The procedure for Mazdas and Fords is as follows:

Insert the first programmed key into the ignition and turn it to the RUN position (do not start the engine), wait for the security light to go out, remove key.

Insert the second programmed key into the ignition and turn it to the RUN position (do not start the engine), wait for the security light to go out, remove key.

Insert the NEW key into the ignition, turn it to RUN (engine off), wait for the security light to go out.

The key is now Programmed.

The procedure for GM vehicles is similar except you only need to cycle the ignition once with the first key, take it out and insert the new key, turn the ignition to RUN (engine off). When the light goes out the key is programmed. This should work for all GMC, Pontiac, Cadillac, Chevrolet, Buick, Saturn and Hummer vehicles. This should be a time saver for people who would like to purchase these chip keys online.

To have these keys cut, any local Locksmith in your area should be able to do it for you at a very minimal charge.
