2010 fusion auto door lock on exit

I need to have the doors autolock upon exiting the vehicle. I don't want to rely on my memory to hit the remote lock. I need it auto'd. I'd prefer to not install a complete security system, it shouldn't be necessary. If there is no after market module or system, can someone give me the schematics for the fusion SE? I can build a delay timer if I can get a hold of the wiring diagrams. All I need is the key "out" of the ignition signal and the Door lock side. Monty

Key Sense

BLUE/GRAY

(+)

IGNITION SWITCH HARNESS

When the key is removed from the switch, the positive voltage should go away from this wire.  You should check with a meter to verify this.

PowerLock

BLUE/GREEN

(-)

AT SMART JUNCTION BOX BEHIND DRIVERS SIDE OF DASH ABOVE KICKPANEL

This requires a negative puse to lock.

Just what I needed. Just a quick question: Does the Blue/Green Power lock do all 4 doors? Monty

I might point out that when I enable auto arm AND lock on alarms, I get the customer to sign a release waiver. There is no such thing as "I will never leave the key in the car".

Thanks but that's why I want to use the 'KEY SENSE" line as a must for activation. If the key is in the ignition the doors won't AUTO LOCK or am I missing something? Monty

Quite right and since I haven't got a clue what a Fusion is, you'll have to find out whether it has one and use that as a relay interlock for the locking.
