I have three remote key fobs and can successfully enter program mode and all three 'keys' test OK while in program mode. When I turn off the engine and exit the car, the key fobs do not work! The driver door lock/unlock button works, the key fobs have new CR1616 batteries and their LEDs light brighty--but do not work!

I am the newest owner of this 2004 Honda Accord, there have been two previous owners. I just got one key with the Accord and its remote entry buttons were missing (I replaced 'em). No telling what was done to disable remote entry due to past lost keys, etc. I know that programming mode erases any previous key fob identities, but have no idea what the previous owners/dealer did.

During programming, I hear the 'successful' sign of the muted thump in each door for each of my newly programmed key fobs. Again, the key fobs do not lock/unlock at all! But, without a car wiring diagram I don't know if pulling a relay or program option can disable remote entry all together. It appears that the programming phase 'door thump' just doesn't connect to each door lock actuator--even though the inside driver door lock button really does actuate all door locks to lock and unlock!

Here's the programming sequence:
Transmitter Programming

Storing transmitter codes:
The codes of up to three transmitters can be stored into the keyless receiver unit memory. (If a fourth code is stored, the code which was input first will be erased.)

NOTE: It is important to maintain the time limits between the steps. Make sure the doors, the hood and the tailgate are closed.




Turn the ignition switch ON (II).
Within 1 to 4 sec , press the transmitter lock or unlock button with the transmitter aimed at the keyless receiver in the power window master switch.
Within 1 to 4 sec , turn the ignition switch OFF.
Within 1 to 4 sec , turn the ignition switch ON (II).
Within 1 to 4 sec , press the transmitter lock or unlock button with the transmitter aimed at the keyless receiver in the power window master switch.
Within 1 to 4 sec , turn the ignition switch OFF.
Within 1 to 4 sec , turn the ignition switch ON (II).
Within 1 to 4 sec , press the transmitter lock or unlock button with the transmitter aimed at the keyless receiver in the power window master switch.
Within 1 to 4 sec , turn the ignition switch OFF.
Within 4 sec , turn the ignition switch ON (II).
Within 1 to 4 sec , press the transmitter lock or unlock button with the transmitter aimed at the keyless receiver in the power window master switch.
Confirm you can hear the sound of the door lock actuators within 1 to 4 sec , then push the transmitter lock or unlock button again, or the code will not be stored.
Within 10 sec , aim the transmitters (up to two additional ones) whose codes you want to store at the keyless receiver, and press the transmitter lock or unlock buttons. Confirm that you can hear the sound of the door lock actuators after each transmitter code is stored.
Turn the ignition switch OFF, and pull out the key.
Confirm proper operation with the transmitters.


If you've done this and the fob(s) still won't work you may need a proper scan tool to read the module data and verify all the criteria are met for both programming and operation.
