speed controlled door lock/unlock

[llajumpvid]

For you wiring experts what would be the easiest way to add auto lock/unlock. I’m not talking about the auto relock function. I would like the doors to lock when my speed exceeds say 5mph and unlock when I shut off the car. Would one of those PIC thingiebobs discussed in the navigation disclaimer thread work?

This thing is close to what I want but it doesn’t unlock when the key is turned off due to the retained power. Plus I do not want it to lock when the key is turned on...I know I will be hitting the lock unlock button 5 times as my wife will likely not have the door open before I turn the key and then I will unlock it as she pulls the handle etc...

not sure what is available specifically for this, but some clifford alarms have rpm controlled door locking. since viper owns clifford now, i am not sure if this is still a clifford-only option. need an alarm???

I concur with TIsTan.
