Slight problem...While installing a remote start/keyless entry on a Rav4 I ran into a problem with lock/unlock. I used the 451M as a five wire, and when connected the remote only locks and unlocks the driver side door...not the passenger or rear doors. Does anyone know what would cause this? What can I do to correct? Thanks

try setting your unit for double pulse on unlock.

This sounds as if you are on the wrong wires with the wrong setup. You did not mention which starter you installed but with most starters they offer negative pulse output. This means there is no need for the 451M in that vehicle. Here is what DEI lists for your door locks:
Power Lock blue/orange - DKP, 14 pin plug in pin 6
Power Unlock blue / YELLOW (double pulse) - DKP, 14 pin plug in pin 13
Lock Motor blue/orange 5wi DKP, 14 pin plug in pin 2
Unlock Motor blue/red 5wi DKP, 14 pin plug in pin 7
From what you posted it sounds as if you hooked into just the driver's door lock motor. Just sending a negative pulse to the blue/orange will lock the doors and sending a double negative pulse to the blue / YELLOW will unlock all doors.

The Rav4 is negative pulse locks. Remove the 451m and connect the lock/unlock wires from your keyless directly to the blue/orange and blue / YELLOW wires. It will unlock the drivers door on the first pulse and the others with the second...
