unless the honda wizard,zippie1 comes in and sees this,he may have a rabbit in his hat to help you,he's good just like Tom Brady just showed the WORLD times 5! To use this chart, please find your problem on the numbered list. Then, look below to match the problem's number to the replacement parts.
Master or Valet key has been lost or addition Master or Valet key is required.
All Master and Valet keys have been lost.
Learning key has been lost.
Immobilizer receiver does not work.
Immobilizer control unit does not work.
ECM does not work
Ignition switch does not work.
Door key cylinder has been broken.

1. Parts Set: A | PGM Tester required : Yes
2. Parts Set: Ax2, and B | PGM Tester Required : Yes
3. Parts Set: B | PGM Tester Required : Yes
4. Parts Set: C | PGM Tester Required : No
5. Parts Set: B | PGM Tester Required : Yes
6. Parts Set: E | PGM Tester Required : Yes
7. Parts Set: D | PGM Tester Required : Yes
8. Parts Set: F(G) | PGM Tester Required : No(Yes)

Part Sets

A: Blank Key
B: Immobilizer Control Unit, Master Key, Learning Key
C: Immobilizer Receiver
D: Ignition switch with immobilizer receiver, Immobilizer control unit, Master key, Learning key.
E: ECM
F: Door key cylinder, Master keys for doors open or locked
G: Ignition switch with immobilizer receiver, Immobilizer control unit, Master key, Learning key, Door key cylinders, Trunk key cylinders.

(With problem number 8, solution/part set F will simply replace the broken door lock cylinder with a new one, and you will receive a new key or keys for that door or doors, you will end up with more keys for your car. Solution/part set G will replace all lock cylinders, and immobilizer system with new parts, your old keys will be invalid, and you will receive a new set of keys for your car.)

NOTE:
The immobilizer system can store up to five key codes.
If it is necessary to rewrite the immobilizer control unit to learn a new key, the dealer needs the customer's vehicle, all it's master and valet keys, the learning key, and a PGM tester equipped with an immobilzer program card. Any key that is not learned during rewriting will not longer start the engine.
If the customer has lost their key, and cannot start the engine, contact Honda customer relations.

Beyond this in the manual are wiring diagrams, and testing procedures. I highly advise against attempting any of these at home. Save yourself the headache and have AAA tow your car to the dealership. Attempt any testing or diagnosis of the immobilizer system at your own risk.


Summary

Each car came from the factory with one(1) red learning key, two(2) black master keys, and one(1) gray valet key. The red learning key that came with the car is paired with the immobilizer system. The red learning key that came with your car is the only red learning key that can be used with the immobilizer system in your car.
If you lose your red learning key and your other keys, you will need a new immobilizer system. Prices vary, but this is expensive.
If you've lost any other combination of keys but retain your red key, get your car to the dealership, making sure you bring your red key and any other keys you may have left. The dealership can then make you a new key and program your immobilizer to recognize it. This is relatively cheap.

I'm aware of many people posting about alternatives to Honda's repair/replacement procedures. I personally cannot confirm these to be true, and in the same sense cannot confirm them false. It is your choice and your choice alone which route you choose to take to get your car running again. Best of luck.
so i am assuming your answer is this>2. Parts Set: Ax2, and B | PGM Tester Required : Yes! 2 keys and the Immobilizer! your switch alone,depending on if automatic or stick is over $400.00 for an aftermarket switch includes lock cylinder and electrical part,but not the Immobilizer and or programming...
