    Alright guys, I finished everything up. Only took about two hours, and that was taking my time. This my first write up so bear with me. These are harder to make than you think!

    This will give you the ability to lock and unlock your truck from the outside. The toggle switch will allow you to activate and deactivate the unlock button. This will make more sense later on. Why would I want to do this you may ask? For me, it's so I can run into the store while leaving my truck running to keep it cold in the Florida heat. This will also work with the truck off, so it's great for locking your keys in the truck at a beach, hiking, etc. Anyways, here's a mini write up.

    Disclaimer: Check your local laws first because in some states it is illegal to leave an unattended vehicle while running. You are solely responsible for any work you do on your truck and if you get your truck broken into because of this. Proceed at your own risk!

    What you'll need:
    Tacoma
    Two momentary push buttons
    http://www.amazon.com/Support-Black...&redirect=true&ref_=oh_aui_detailpage_o00_s00
    Toggle Switch (Optional)
    Two 18-22 gauge wire taps
    Wire
    Misc. Electrical connectors

    Tools:
    Drill with 1/2" bit
    Dremel with cut off wheel
    Wire strippers
    Wire cutters
    Electrical crimper tool
    Soldering iron (not what I used, but preferable)

    Step 1:
    Figure out where you want to hide your buttons. I have no problem showing you where I hid mine because 99% of the time the unlock button won't be active. I put mine right inside the grill. The two points where the grill attaches on top is hollow, so I took advantage of that.

    Step 2:
    Mount your buttons. The ones I linked require you to drill a 1/2" hole. If you plan on mounting in the same spot that I did, you'll be required to use a dremel and cut out the bottom portion of where the buttons are mounted.

    Step 3 (Optional, but recommended):
    Mount your toggle switch. This will make it so your unlock button isn't active all the time. Now not just anyone can come up and unlock your truck. This is where I put mine.
    20160414_193450.jpg

    Step 4: Ground your buttons. The way this mod works is by sending a ground to the wires we are tapping into. No 12v needed! This is where you should use a soldering iron to connect the wire to the buttons. There isn't enough room between the closed hood and the top of these buttons for a typical blade connector. I used this stuff I had which is basically a plastic version of a soldering iron. Pretty neat!
    20160415_162523.jpg 20160415_163223.jpg

    Step 5: Now comes the fun part. Figuring out which wires to tap into! You're going to tap into the green/black wire for the unlock button and the purple for the lock button. These wires are located behind the driver side kick panel. If you want to test the wires before you tap into them (I would) then here's a simple way to do it. Take a small strip of wire (12" should do) and strip each end off exposing about 1/2" of copper. Shove one side into the connector with the wire you want to test and tap the other side against a good ground. If it locks/unlocks, then you've got the right wire!

    Step 6: Now that you've got your correct wires tapped, you have to run them through the firewall and to the other connector on your buttons. If you've got the toggle switch, make sure you run it through that first.

    Step 7: Make sure and test everything out, and you're done! This isn't the best write up, so feel free to ask any questions.

    Not sure if you mention this in your write up, why not toggle the lock also? I could see my keys in the truck and some mechanic or other hitting that button looking for the latch. Now the keys are locked in.

    A good point for some to think about. My button is tucked up in there pretty good and it would be hard to accidentally hit it. A DPST toggle would be a good idea, so then you could toggle them both with a single switch.

    Plus for extra insurance I have a "dumb" key hidden outside my truck, in case my battery is ever dead and this method does no good.

    Pretty cool idea. A cheaper alternative to remote start. ( with remote start you can press a button to let it run and take the keys with you ).

    Here's the only problem that I see with this. Around here in Ohio, they can and will tow your car if you leave it running with the keys in it.

    Really? That's pretty ridiculous. Even if it's in a parking spot?

    Interesting idea OP - Its illegal to leave a vehicle running and unoccupied here but I suspect this would get ya around that law once explained to the officer

    Yep. They put in on the news right before winter and summer every year. It's because of car thieves. If you have remote start, it's ok because they cannot drive off

    Would this be similar enough for them to allow it since the car is locked? Or no, because they could just smash a window and pull away.

    I don't think I'll have any problems with the law. Fingers crossed at least! Besides, longest I'd leave it running and unattended would be a couple minutes. I've done it for years, just with an unlocked car, and haven't had any issues yet.

    This isn't remote start dude. This is door lock/unlock. Say your at the beach and want to leave the keys in the truck.

    Yes I just noticed that. Nice work. Been meaning to do something like this just can't decided on a location that won't attract attention.

    No, at least not in Ohio. Locked doors don't make a difference. People have used spare keys to lock up a running car only to find it missing when they got back. Along with a huge tow bill. Be careful and check the laws in your area. Maybe it's different where you are

    Another great use for it that I plan on utilizing. As far as the remote start, some allow you to leave your car running, but pull the keys out and lock it so it's secure.

    This would be cool if it still works with the truck not running.. Be nice for going to the beach - could lock keys in the truck and not have to keep up with them

    Got it. Guess I shouldn't skim posts before I reply. Truth is I just read this to get an idea of where to put my buttons. I didn't think of using this to leave a car running with keys inside.
