2003 Tacoma Keyless Entry Remote

I just bought a 2003 Tacoma PreRunner V6. It only came with the keys but NOT the remotes. I am looking to purchase the remotes. I found the "transmitter"?/ left side under the dash and its a Python. Does anyone have any info on these and can I still get remotes that are compatible?

 

You may actually have the factory receiver. Remove the left foot kick panel on the driver's side. If you see the RS3000 unit there, you just need to program a key fob to it.

 

I think that I have located the receiver that you are talking about but it says Python on it.

 

I have one of those python systems in my 01,

luckily I had a FoB from the Previous owner

this is what my key fob looks like if that is any help.
