If a Toyota key is reprogrammed does it change the way a stolen key works?

I had a secondary Toyota key stolen. If I get my original key re-programmed will the secondary key still work? What do I need to do to keep the stolen key from working with my car?|||To be 100% secure you may have to change the whole locking system i.e. security device, immobiliser, door and boot lock and lastly the ignition lock. Seriously speaking can you afford it when Toyota is charging 拢180 simply to make out a duplicate key, what to talk about changing the whole system simply to deactivate the stolen key? You will be better off just change your car.|||If the key has a chip you are probably going to need to change your locks and ignition. While you may be able to reprogram the key for secure entry, it will be costly because now you are talking about changing your ignition. Don't forget the doors, which the valet key can open if someone has an imprint of the card.|||YOU CAN GO TO YOUR NEAREST TOYOTA DEALERSHIP AND HAVE YOUR IMMOBILIZER SYSTEM RESEEDED.THIS IS DONE BY SIMPLY CONNECTING A COMPUTER TO YOUR VEHICLE AND IT WILL CHANGE YOUR SYSTEM SECURITY CODE.WHEN THIS IS DONE,ONLY THE KEYS THAT GET PROGRAMMED BACK IN THE SYSTEM ARE THE ONLY ONES THAT WILL BE ABLE TO START THE VEHICLE.IN HOUSTON,TEXAS U.S.A. THIS COSTS ABOUT $180.00 U.S.THE KICKER IS THAT THE STOLEN KEY WILL STILL BE ABLE TO OPEN THE DOORS,BUT DOOR LOCKS AND IGNITION CYLINDER CAN BE REKEYED FOR ABOUT $300 U.S.I THINK THAT SPENDING $500 TO$600 TO HAVE YOUR CAR SECURED AGAIN IS WELL WORTH IT.GOOD LUCK.
