Automatically Locking Doors When Driven?

[rsg]

I've heard that a few people have automatically locking doors, either when put in Drive for the first time after being started or after going over a certain speed. Is there any way I can program my '94 LS400 to do this?

The "auto lock" feature was first available on the 2001 LS, GS and SC models. It is not a customizable setting on earlier models.

if you install after market security system such as blackwidowsecurity.com this feature will be available. the blackwidow on my 90 ls400 will lock all doors a moment after key turns to ignition. quite useful
