Check Fuse #9 under the hood its for DLC Power and Immobilizer System (10 Amp).
Look at the TDC wire harness. Sometimes the
wire isnt put back in the holder on the rear edge of the timing cover.
Then the harness gets sawed in half by the alternator belt.
Other Honda user had this problem on his 2005 Accord, after letting it
sit battery disconnected for 20 minutes it was just fine. Inmobilizer
for the lose.
My guess is your immobilizer kicked in because your battery in your key is dead.
So, I dont warranted if this process work...
Here is a better understanding of how a immobilizer works; each key
has a code imprinted on it, no battery of any type just a random code.
When you go to start the car the immobilizer computer sends a signal to
the key. If the signal it receives back from the key matches one of the
5 keys it keeps in its memory, it sends a "OK start" message to the PCM
starting the car. If it doesn't see the "OK start" signal it doesn't
start and the green key light in the dash flashes. In short there is no
way to reset it.
Try another key. If not, there is a way to bypass it
shortly to get the car to a Honda dealership for reprogramming of a key
or key replacement. Your Prelude may also have a problem with one of
these components. It will need to be hooked up to a Honda scan tool and
checked for immobilizer codes.Let me know if you have any questions.

I will try and answer all I can.Here is
how to use the "pcm brake code" You weill need to call your local
dealership and give them you vin # to get the code.To start the engine,
follow this procedure:
1. Cut a temporary key using the key code and
anon-transponder key blank.
2. Turn the ignition switch ON (II) with
3. Enter the first digit of the immobilizer brake
codeby pressing and releasing the e-brake pedal the samenumber of times
as the digit. For example, if thefirst digit is 4, press and release
the e-brake pedal 4 times.
4. Turn the ignition switch to Lock (0) and
then backON (II).
5. Repeat steps 3 and 4 to enter the second,
third,fourth, and fifth digits of the code. You have up to30 seconds to
enter each digit.
6. After you enter the fifth digit, the
immobilizerindicator on the dash will blink five times,meaning you can
now start the engine with thetemporary key.While the engine is running,
the immobilizerindicator will stay on. If the engine isn't
started with in 10 minutes, you'll have to reenter theimmobilizer brake
code. You'll also have to reenterthe code if the engine is shut off
for more than 10 minutes.This also workes for any Honda immobilizer
system. However you need to use the brake pedal. Only preludes you used
