Auto lock feature?

So I have my keys hanging up by door so I hit unlock once and leave it there, and then go outside to my truck(slowly) and as I finally get to it, it automatically locks as I reach to the door. Has anyone heard of that happening? I have a 2008 tacoma trd off-road with manual trans. Thanks

 

Mine does that.

 

It's a security feature.

There are far more Toyotas than there are remote codes.
If the door is not opened within some preset time (20, 30 seconds?), the doors automatically re-lock.

That way you don't come out to a parking lot and find your truck unlocked because someone parked close to you happened to have the same code.

 

That's on a short list of my gripes with this truck (http://www.tacomaworld.com/forum/2nd-gen-tacomas/261103-2013-tacoma-i-gripe-therefore-i-am.html). I've been in to my local dealership for the included first few services and ask about disabling or lengthening the duration every time I go. They always tell me you're stuck with it. On some of the other models (pass cars) you can up the time to 60 or 90 seconds but we seem to get the short end. Again.

 

This reminds me of a time I got up early one morning at a hotel only to find that my truck was running outside. Somebody's remote start started my truck, they drew a little smiley face in my windshield in the snow before they left.
