I just bought my 06 4runner a week ago, it is great except if the engine is off and I close the window before getting out, next time I use the car the doors are locked, and the battery does not have enough power to turn over the starter but enough to run the lights. Is this something electrical or just an old battery about to give it up. I think it is the original battery. This has happened to me twice in the week I have had the car.

Could be the battery...or something is draining the battery.
The starter needs a lot more amps then what the lights need...more then 10 times more amps.
Many places will test the battery for free. I just replaced mine on my 05. If you live in warmer climate then battery life is shortened compared to here in NH.

Autozone/ Advance Auto Parts/ Any reputable car store:
They all have a battery cart that is a computer they hook up to your charging system and battery. They can check your battery and alternator. This sounds like you either have a bad battery or something is pulling an excessive amount of power with the car off. This is almost ALWAYS something aftermarket. Toyota/Most Car makers spend good money on making sure that all their gizmo's and computers don't kill the battery. Usually someone will install a aftermarket this or that and not be quite so careful about how they plug it up... and it eats the battery.
1. Test the battery. 2. If they tell you the battery is good, is there anything aftermarket installed? Headunit? Amp? Sub? Alarm system? Media something another? Lights..????
If it isn't 1 of those, come back...

Any completed circuit can drain power... but if the circuit is completed, then the device would be in constant operation, and I feel like that would give itself away.
Unless it burns out...
Does your truck hatch open correctly? If so, then the latch circuit is not stuck in a completed cycle.
Second, the rear window lock is not an active circuit, meaning it doesn't create a "complete power circuit", it actually interrupts one. Does that make sense? All the rear power lock does is psychically disconnect the power transfer line for those 3 windows controlled by it. This means is it a passive and purely mechanical lock. No electricity is used to "lock" the windows.
It would be possible for an individual window motor to be blow, and stuck open, draining power. This, again, would make itself evident by an inoperable window motor. In this case, engaging the window lock would actually stop it from occurring, as it would be shutting off the transfer path for the electrical signal and power.
Make sense??
So, here is what I suggest. The only way any of what they said in those two cases to be true, is if you had a serious malfunction in your latch and window. They are not complex CPU circuits. They are simple 2 state latches. Power - open, power - close. Meaning, pressing the window button, or the open back latch simply transmits a momentary electrical pulse that actives ONLY BRIEFLY the mechanism.
Make sense? SO. Check the function of every door lock. Latch. Window. Up, down. Lock.
If it all works. They are wrong.
