Keyless entry gone haywire

A new problem for my Tacoma, my keyless entry is acting like it has a mind of it's own. What I mean by this is, I will get out of my truck, lock the truck, walk away, and then as I approach the truck again, the truck will arbitrarily lock or unlock itself without me touching the door handle or key fob. Has anyone else had this issue? I have no idea why it has started doing this, other than there must be some type of malfunction with the keyless entry system.

 

Battery. Change it.

 

Ok, thanks for the reply, I'll give it a shot, hopefully that helps.

 

The keyless entry "learns" your ingress/egress habits, just like the AT "learns" your driving habits?

 

Ok, that seemed to work. Thanks again. I was confused, I previously owned a 2010 4Runner, and when the battery started going with that, the truck just wouldn't unlock unless I used the actual key. This was the exact opposite, it seemed to hyper-charge the key fob into getting the truck to lock/unlock. Weird.

 

It does not, I've had the truck for almost 2 years, you have to be touching the sensors. In this case, it's like the truck was possessed. Anywho, it seems to have been remedied.
