456M alarm?

Does anyone know how or whether the 456M immobilizer (which may be the same as the 550) can be set so that the unlock or disarm button on the remote does NOT have to be pressed before the starter can be activated. I am looking for a "valet" mode but the instructions seem quite clear that it cannot be disarmed except with the number sequence input by key turns. After which presumably the alarm and immobilizer are permanently "off" and (again presumably) have to be reactivated with the key turn sequence????

 

Its great - an amazing sleeper. Very fast 0-60 in the high 4s and will pull its red line in 5th at about 150 (BTDT) corrected as the spepdo reads 165 on 16" factory asphalt metrics.

Can be interesting on the track especially with the rear diff locked! A car well ahead of its time (about 6-8 years) but not considered a collectibel in the US by the B-J crowd.
