2001 Blazer door lock programming

The owner's manual of the 2001 Blazer says it is possible to program the door locks to automatically lock when the car goes above 15 mph and unlock when the ignition is turned off, but it doesn't say how to do this.

Anyone know how to do this!

Thanks!!!!

Perform the following steps in order to personalize the automatic door locks:

Turn the ignition to the OFF position.
Pull the turn signal/multifunction lever all the way toward you and hold it there.
Turn the ignition to the OFF position and then to the ON position twice.
With the ignition OFF, release the multifunction lever.
The doors lock and then unlock to signal entry into program mode.
Select one of the following options for the automatic door lock (all of the doors lock when the vehicle speed is 15 mph or above for more than 2 seconds) and the automatic door unlock (when the key is removed from the ignition):
To disable the automatic door lock feature and the automatic door unlock feature, press any door lock switch twice.
To enable the automatic door lock feature but disable the automatic door unlock feature, press any door lock switch once and then press any door unlock switch three times.
To enable the automatic door lock feature and the driver side door unlock option, press any door lock switch once and then press any door unlock switch once.
To enable the automatic door lock feature and the all door unlock option, press any door lock switch once and then press any door unlock switch twice.

Exit Programming
Either of the following events will cause the programming sequence to be terminated:

The ignition is turned ON.
10 seconds elapse with no input from the door lock switches.

Will this work on any other model years???

Also how do you perform the programming to have the locks automatically unlock if the key is in the ignition if you close the door while not running so as not to lock yourself out. I have seen it on a 1999 GM truck, thought it might be possible on other models/years.

Thanks fopr your help.
