This is in a 2001 Honda Prelude....

Alarm (Firstech 2000AS) started acting a little strange (one issue was that it wouldnt remote start anymore), so I decided to rip it fully out and upgrade to the CM3000.  After installation, everything worked except the remote start. When I tried testing the remote start from inside the car. the first try using the 555u bypass, it didnt start, then I put a good key in the ignition it started right up. So I figured the bypass went bad. I got a newer 556U and installed it (again using the Status wire as the trigger) and it still didnt work. So i took the cut ket out of the 556u and put it near the ignition...still nothing.  Then I did the same thing with a good key..just putting it near the ignition...and it started right up.  So it seems like the chip in the key being used origianlly just stopped working? Is this common?  Thanks

i have never seen a key go bad. you should use a data bypass so you dont loose the extra valet key.

It's definetely the key that went bad, and the reason i know this is that when i use another key (one that actually is able to start the car normally) in the 556u the car remote start perfectly. This other key, that supposedly went bad was in the car in a 55u from 2001 till now, so the original valet key worked in the bypass unit for 7 years, and then decided not to anymore. i guess everything is prone to failure at some point...maybe the internal battery to the chip just went dead...just a guess

No battery in the key itself.... it is just a passive RFID pellet. You could head to the dealer and see if they can reprogram the key to the car. It may have just kicked it out. Have seen Audis, the odd VW, Fords and Chryslers all decide to drop a key every once in a while. It does happen.
Wherever I go, that is where I end up......
