2008 saab 9 3 door locks

Bare the two wires just before you joined to the resistors with all doors closed and the key well away from the ignition then ground each in turn. If it works properly there's something wrong with the 451 (extremely unlikely). If it doesn't one of your motors needs replacing. What happens if you use the OEM remote?

Just re-read your last post, lock and unlock wires from the alarm will either read 12v+ at rest and go to 0v when either lock or unlock is selected. The two relay output wires, green and blue will read open circuit at rest going to 0v on arm (l0ck, the green) and disarm (unlock) the blue. Any other result, check your wiring on the 451. Brown and white not used, purple to ground and make sure the thin red input from the alarm is 12v+ all the time.

And for my next trick, I will reverse the lock and unlock circuits and expect things to work normally. Besides reversing things, I reconnected the ground, and combined the lock and unlock wires instead of how I originally had it. I had two wires going to the lock switch, one for lock and one for unlock. Closing the door to try the lock also helps. Anyways, thanks for the replies. Everything is working as it should. As a side note, I have remote start working in my Saab. Though my searches on different forums, I see a lot of people say that it can't happen. I can't take credit for it, but a member of another forum was able to reverse engineer the ignition system and build a bypass for it.
