How do you get transponder key and program myself?

Answer 1

To get a transponder key, you can order a blank one online or buy it from a dealer or locksmith. To program it yourself:

Insert your existing working key and turn it to “On” (not start).

After a few seconds, turn it off and insert the new key within 10 seconds.

Turn the new key to “On” and wait for the security light to go off (usually takes a few seconds).

Answer 2

You can purchase keys from Locksmiths, dealerships, and from the internet. I would recommend using a professional just to make sure you get the right key and not waste your money, plus they can cut your key correctly (which internet sources can't do).

And with the programming side, it depends on what car you have. Not all cars have on-board programming available, and from the ones that do you may need 2 already programmed keys to do so. A good place to go to for free programming instructions is http://www.programautokeys.com It doesn't have every car but its worth a look.
