I am going to install a remote start with door locks on my wife's car and was wondering if anything else is needed to work on this car besides a remote start kit?

Don't think the U.S. models had a transponder immobilizer system. I did a 2004 Optima a while ago and it did not need a bypass. Pretty easy car to do.
+12V Constant Red x 2 @ Ignition Switch Harness ( to right of steering column )
Starter Yellow @ Ignition Switch Harness
Ignition Pink @ Ignition Switch Harness
Accessory 1 Orange @ Ignition Switch Harness
Accessory 2 Brown @ Ignition Switch Harness
Parking Lights(-) Light Blue @ 12 Pin connector at headlight switch
Horn (-) Yellow Steering column
Brake (+) Green @ Brake pedal switch
Lock (-) White Black Plug lower side of fuse box
Unlock (-) Blue Black Plug lower side of fuse box
Trunk (+) Blue Low in drivers kick panel in harness going to rear. There are 3 Blue wires in the bundle, test.
Tach (AC) non-common color wire @ any F.I. ------------- Soldering is fun!

3 ways to see if it has an immobiliser.
a) Remove the key from the vicinity of the car, try and hotwire it.
b) Remove the cover around the ignition switch. Is it bare, if so no immobiliser, if it has a plastic cowling with a plug and 2-4 wires (not the ignition switch wiring), then there's an immobiliser.
c) Install the alarm then see if it starts. If not and it only starts with the key in the ignition, you have an immobiliser.

Another test for a transponder immobilizer is to get a plain key made at the local hardware store for $1.99 and try to start / drive the car.
Looks like they started needing a bypass in 2007. DEI, Fortin & iDatalink do not list a bypass module for the 2003 KIA Optima. You should be OK. ------------- Soldering is fun!

Of course the other answer is to stick with the leading brans e.g. DEI (Clifford, Viper Hornet etc.), Compustar, Audiovox/Code, Autopage, and check the specs of their products against what you require.
No fleabay because generally unknown brands = no warrantee or tech back-up.

Always solder and quality electric tape ( Scotch Super 33+) or heat shrink tube where possible. As Howard says " Read my By-line ".  ------------- Soldering is fun!

110% with Kreg here. In fact in the UK we are only allowed to solder the joints, at one time we even had to use the crimp ring connectors that you heated after!
I even import Scotch 33+!
Read Kreg's bye-line and go to the General Discussion section where the pros and cons of different connection methods are discussed, you may not be too surprised the all the pros have the same idea...solder!

P.S. If I remember correctly there are even how to instructions but the two main tricks are to heat the wire first then let the solder flow. Result, a nice shiny low resistance "wet" joint

Just takes a little practice and a decent soldering gun or iron. I use an old WEN Model 199K soldering gun that has dual range, 100 and 140 watt, unless the location is very tight. Howard uses a high tech butane iron. There are some "How to" posts with more info on the forum.
Most of professionals do the entire install with the battery connected. Just have to be careful with the +12v constant wires. ------------- Soldering is fun!
