Security problem, Immobilizer locked the car
My son's 99 Honda Prelude had a bad ECU. The car could run with it but not
properly. So he bought a used ECU and replaced the original. The problem is
that the immobilizer, now, doesn't let the car start with either ECU.
Is there a way to reset or deactivate the immobilizer?
Thank you

According to the Service Manual for my 99 lude, the immobilizer can store up
to 5 key
codes. When learning a new key, the dealer uses their PGM Tester to rewrite
the
immobilizer and needs all the coded keys including the red LEARNING key.
Furthermore, "if someone tries to start the engine with the learning key,
all master and
valet keys must be relearned." Maybe that's why the original ECM doesn't
start
the car now. I saw that warning when I bought the car, never opened the
package,
and filed that key safely away.
The last note about substituting a known good ECM is that it must be
rewritten
with the PGM Tester. Since I've never had this done, I'm not sure if the
original
and substitute red LEARNING keys are needed for this procedure or if they're
generic.
Bottom line, it sounds like you will be able to reuse your expensive
original keys
with help from the dealer.

Re: Security problem, Immobilizer locked the car
As was said you are in for a trip to the dealer to program your keys in the
immobilizer system....
