Mine just locked. I am hoping that the graphite spray will help. Has anyone else used the spray besides Hyundaiuser? I am going after work to go buy the spray and try to unlock the ignition. If anyone has used the spray as well please reply.

Fixed the problem. It was $150 fix by a locksmith. The problem is in the key. They are made very cheaply with soft alloy's that the sharp edges get rounded out. The locksmith made me a key with a small file and 10 min later wahla! It turned and started. Hopefully this will help a few if the problem occurs.

This problem is fairly common on Hyundai Sonatas and seems to occur somewhere between 50K and 70K miles. On my 2006 Hyundai Sonata which has 70K miles I had this problem. SOLUTION: Spray powdered graphite into the lock and work the key in and out to distribute the graphite. It may also help to spray the key itself. Also turn the steering wheel while trying the key. Be patient and repeat this process until key turns. I had to give it 5 sprays before it worked and now it works like new. You can get powdered graphite at the hardware store. Get a small bottle (a little goes a long way and it's inexpensive) that has a small tube attatched so as to get the powder into the slot and try to spray toward the top of the slot. Also it won't hurt to give it a spray every 6 months as preventive maintainance. Also you can spray the other locks on your car. I suggest NOT using WD-40 as liquid lubricants will tend to gum up with dust which is probably the reason the ignition is stuck in the first place. And graphite is the choice for lock lubrication. This simple fix will save you hundreds of dollars and ease your troubled mind. I hope this helps you with your problem. ([email protected])

So if WD40 had been used on the key several times, and you sprayed graphite in the hole, would it mess it up completely? Or could you still use graphite as a solution despite the fact that WD40 had been used a lot in the past.

Did not use the WD40 but did use compressed air to clean out the inserts and then the graphite spray. Used it several times but no positive results. Decided to see if a locksmith could resolve the problem. The 20 mins there he started the car. The pins where stuck i guess and needed another master key with sharp edges to release them. Keep that key handy now.

I had the same problem with my Hyundai Sonata 2006. I tried shaking the wheel and jiggling the shifter and nothing worked. then I saw a small cover for the shift lock release which is just above the P for Park on the shift column. release the shifter and unlock the ignition

I have the same issue with my 5 speed '09. I have sprayed quite a bit of graphite spray which is made specifically for unsticking locks. It I try to turn it while wiggling the wheel, it sometimes seems like it moves a few degree but hits something which seems to be related to the wheel lock.

Time to tap out.

Do I get it towed to my local mechanic or call a locksmith?

Default Key won't turn, ignition locked up

My 2006 Hyundai Sonata LX had this issue in 2010, and now again in 2018. For me, it was the key lock cylinder. Both times it went 'bad' and had to be replaced by a mechanic. I've never owned a car in my entire life where this issue occurred, until I purchased a Hyundai. Not a cheap fix (key lock cylinder, re-keyed or new keys, locksmith). Luckily for me on both occasions, I wasn't far from home. I do know from others I have spoken with (family/friends), in most cases its not the key lock cylinder. Sometimes you just have to crank hard the steering wheel to the right or left to release the locking mechanism in order to get the key to turn. In any case, it's always best to have it checked out as you don't want to get stranded.
