You have no key at all? If that is the case you will have to go to your Honda dealer for a replacement because the key has an electronic chip in it. Most locksmiths can't replace these type keys. It will cost what it will cost and fair price has nothing to do with it. You will pay what they require as you have no choice.

Getting a replacement key is simple if you have kept the key number tag. However, the task becomes quite a bit more challenging without the key number tag, which provides the key-maker with necessary data. Replacing the key may get expensive because most modern-day Honda keys are technologically sophisticated devices with electronic circuits that let you to do things like lock the car doors remotely. In addition, a Honda car equipped with "immobilizer" anti-theft protection will not start unless a properly coded key is inserted in the ignition.

If you can't locate your Honda's key number tag, contact the dealer where you bought the car. The dealer might have recorded the key code information when he sold you the Honda. Even if the dealer does not have that information on hand, he should be able to advise you on how to get a replacement key. This process might take some time and will likely require you to prove ownership of the car.

If you have a key, they can reprogram a spare for you for about $50… Or they can order one based on your VIN number for about the same price. It just takes a few weeks. If you want it sooner, they will have to replace the ignition switch and provide a pair of new keys.

If your key didn't have a transponder, it can be reproduced for $5-$10.
