New Tacoma owner with questions!!

Hello all,
Just bought a used 2013 Tacoma PreRunner 4x2 for a pretty good price, but I've noticed there are a few things missing. A key and two remotes for starters- I was given only one key, and I'm thinking that since it does have power windows and power door locks, it might be equipped with keyless entry. I would love to find out, and understand that can be determined by my VIN #.
How might I go about that?
It also has bluetooth built in and it will connect to my phone, mute and ring when a call comes in, but says "no microphone- handsfree will not function" on the display. I took out the overhead console and found the mic is there- it's just disconnected. The four wires have been removed from the plug in the side of the mic- red, yellow, black and white- I just need a schematic to figure out the order in which to connect it up!
There was also an instruction sheet on how to remove the back up camera and cover the cables to prevent contamination, so I am now assuming it also could be as simple as plug and play if I buy a camera for it. It is equipped with the factory Panasonic touchscreen stereo, but a standard rear-view mirror.
I would appreciate any help you could provide.
Thank you all in advance!

 

Welcome!
Did you buy this privately? If it's from a dealership they should've given you both keys & remotes and fixed that microphone no questions asked...

 

Actually bought it through a credit union used car sale; it was provided through Metro Auto Group- a collection of dealers in the area that does NOT feature a Toyota dealer. I asked for it, but they said this one key was all they got from the rental company when they turned it in.

 

a rental? How many miles are on it.
