I have an intermittent problem with my 2008 Santa Fe GLS (Canadian model). Sometimes, when I insert the key to start the car, the in-dash key symbol won't come up (while it usually does when everything is fine). When the problem occurs, I have all electrical power and the engine will crank over; The cranking is going very fast but shows no sign of ever turning over and the car will never start. It really looks as if the immobilizer does not recognize the key and so refuses to start the engine. So I have to remove the key, wait some time and try again. Usually, it can take 3-4 times (and up to 15 minutes!) before the key-symbol light comes up again in the dash, and then the engine will start as if nothing ever happened.

This problem occurs approximately once a week, but you never know when.

I went to the dealer just for that problem but they had no clue and could not reproduce it, .... so they ended-up doing nothing to fix it.
So I am trying to figure out what that can be in order to "help" the dealer in helping me.

Note: The car also has a remote starter that was installed at the dealer. It usually works fine. But the problem also occurred a few times with the remote starter trying to start the car by itself. I could hear the never ending cranking noise from the spinning starter, until the remote starter stopped for few seconds and tried again. I had to stop the remote starter manually.

Any help is welcome,

Ozo.

I don't know If you were aware, but if you have another key that is chipped on your key ring next to the key in the ignition it is possible for the sensor to pick up that key and not read the key in the ignition, therefore not allowing the vehicle to start. I found this out when I was at my dealer with my wifes car and they noticed that I had 2 other keys on the key ring that were chipped ford keys, They told me that there is a chance that the ignition could by mistake read one of those keys and stop the car from starting. Until they said this it never occured to me to be honest.

Maybe This can help ?,

I would ask the dealer to replace the key with a newly programmed key. Its a start to getting it resolved.

Make sure you don't have any other chipped keys on your key ring, if you don't, I know a couple antenna coils have been replaced on a few vehicles (Elantra and Santa Fe's) for the same issue and have had better results than replacing the key.

My car key is alone on its key ring, so no chance for another key to cause any problem.
Also, the key itself could be bad, but the remote starter also uses a key (hidden somewhere in the car) and it sometimes also have the same problem starting the car. So I guess it has more chances to be on the receiver side than the key side.

Does anyone know what part in the car integrates the receiver (i.e. which receives the signal emitted by the key)?

Anyone else with similar issues?

I'm with Trucker. Rip out every trace of that remote starter, and I'll bet your problem will be solved.

Better yet, buddy up to the dealership mechanic who's been working on your Santa Fe, and explain that you suspect the aftermarket starter which the sales department sold you. Mechanics hate salesmen, especially salesmen who send the product to aftermarket shops for modification. I can almost guarantee that the mechanic will go out of his way to prove you right, and that the service manager will take great pleasure in billing the sales department for all your trouble. I can also say with a high degree of certainty that the dealership will not be selling remote starters just as soon as the owner finds out what happened.

Yes, I once worked in the car business. Been there, seen that. Many times.

Seeing that it does not seem to be a frequent problem amongst Santa Fe owners, your suggestion is probably the best I received so far.
I'll do that the next time I have my car at the dealer.

Thanks.

I had the same problem and as it was a warranty issue they replaced the 'Antenna Coil' and since then no problems. Get them to check that and see what they come up with.

First of all, I must defend remote starters - they work (if installed properly). I, probably, have to note a low level of qualification of most car mechanics (electricians, to be exact) whose hands are attached to their a**es, not the shoulders...

I have a remote starter (a car alarm with remote start / turbo timer capabilities) - it works.

I do not know all the differences in circuitry of Canadian and European Santa Fes, but I believe that they are very similar.

So the most possible causes of this behavior may be:
  1. Faulty antenna coil as stated above.
  2. Improper installation of the remote starter.

When an aftermarket car alarm was installed in my Santa Fe, the dealer put a blank (third) key in the immobilizer bypass. The OE security system remains in place. The dealer reprogrammed the OE immobilizer to work with new keys. I was told that I would not be able to strt the car with the second key I have, since I did not bring it with me. So I had to bring all the keys later for reprogramming.
