Question about 2005 Hyundai Elantra
Has the spare key been programmed to unlock the security system? do u have a security/immoblizer light of any kind flashing when u try to start the engine? if yes is the answer to the above questions you will need to get the spare key programmed, on this car in order to program the key to work you must have the dealer do it with a special electronic scan tool that teaches the security module to recognize the new key, there is no "at home" programing procedure for this car..

It should start with the spare key ---but in saying this you may not have a chipped spare if you bought the car second hand .If it is chipped then its possible that the chip has lost its memory by being stored on top of the TV or near a radio signal source .Their is no magic mechanics code to start this vehicle ,as its a 2005 then the chances are the vehicle uses encrypted software so its a dealer only job ,if its pre encrypted software then if you can get the four figure code from the dealer then a mobile key man might be able to re-programme the spare for you and programme another key cut from the spare .Often found though its cheaper at the dealer .

SOURCE: My Spare Key Won't Start My Car
ok well here's the thing. This key has not been used before. The keys are cut to the specs of the ignition so they may be undercut so to speak. I know on my car i can turn it upside down it will work. But on the other hand it could just possibly be a back up for when you lock your keys in your car (not likely but it's still possible). You can keep putting your key in and out a bunch of times and **** the steering wheel back and forth as you turn the key to get it used to the ignition switch. See if that works and if not i will see what i can come up with in the meantime for this exact car.

First find little notch on side of FOB that will allow you to open the FOB itself. Next insert mini flathead and twist hard until unti snaps open. Hopefully you didnt break it yet. Then pull out circuitboard within FOB. nEXT remove battery and press red button and hold for 5 seconds. Replace Battery then put circuitry back in place. Now, with circuitry in place hold all three buttons while simultaneously pressing the red circuit overload reset button on the board. Then, press the thre buttons in this exact order ( this is a very important step) press the door unlock buttton twice before waiting three seconds then pressing the hood open button 3 times followed by a 5 second delay then pressing lock> But wait, before you press lock you must "chime" this code to the song "waiting for a girl like you" by foreigner. The code will then automatically find your cars code, get married and then you will be in luck - many baby remotes will start to fall from your dash board. If this doesnt work it is probably due to the fact that you have more of a hard rocker or redneck remote and follow all prior procedures but replacethe song with only "welcome to the jungle" or tears in my beer". If this still doesnt work, grab a beer and share it generously with your remote. When this doesnt work, (as I suspect at this point it wont) take your remote and after finishing the 12 pak, take the remote to your local hyundai dealer and threaten to throw up in the main sales room if they dont program it for you. Mae sure you slur the fact that your dad owns Hyundai (even though you are as white as can be) and that you will sue them all out of work if they dont do this for you ...plus you then proceed to puke on the front door handle and tell the customers " this is what you have to look forward to if you get oneof these BEutieeeesss hahahaha" while rubbing your puke infested hands all overtheir nice shirts and blouses, ....this I promise will work. And you should have a nicely programmed remote the next morning after waking up in the drunk tank and the officer gives you a ride home because the mayor of "yourtown" is your neighbor and your supposed to be at home cooking a barbeque for him that after....HIC...that after...HIC that ...noon.
