Hey guys

I’m on a few forums. Every time I mention I’m a locksmith , people start asking me questions about car keys. Not that I mind , quite the contrary. Here are some of the most asked questions , and a lot of general information.

First off all , I would like to mention that you can just get your keys ordered from the dealership. This will take a while , though. A locksmith can get it much sooner.

Q: What is a transponder and whats it doing in my key ?

A: A transponder is a chip embedded in the key head. When you turn the ignition on , the ecu will transmit a signal to the key. The transponder will then send a reply signal , containing its code. If the code is recognised be the ecu , you'll be able to start the car. If the ecu doesn't recognise the code , the starter will turn over , but there will be no fuel injected into the engine. It will be like the car has a starting problem.
Transponders are used on all European cars since 1994. The name Transponder comes from Transmitter - Responder Unit.

Q: Can I have the key of my Coupé duplicated at the local locksmith ?

A: That totally depends on the type of car and how well equipped your locksmith is.
For the US spec Coupé , you can just get the key duplicated. The US version doesn’t have a transponder. Ours does have one. The US Tiburon has a different ECU than ours , and transponder control isn’t integrated.

Keys for the EU version Gen1&2 can be duplicated at some locksmiths. The Gen 1&2 key has a Texas transponder. Texas transponders can be cloned by a well-equipped locksmith.

If you still have the blue-head key , you can also get a key with a fixed Texas transponder in it. You will have to programm the key into the ecu , for this one to work.
Most locksmiths will be able to order a key like that from their supplier. The key you’re looking for the the HYN6T4 (Silca reference).


From Gen 3 and later , Hyundai switched to a different type of transponder. Its now a Philips Crypto. Untill now , these can not be duplicated yet. We can’t even get an emulator key yet.

Seoullfullracing sells EOM Hyundai keyblanks. For a very low price , I might add. You can order one of these and have a locksmith cut it. The dealership will still have to program it though.


FYI , the key from Seoullfullracing will NOT work for the gen 1&2 Coupé. The type of transponder is not compatible at all.

You can always get a key made without a transponder. But you’ll not be able to start the car with it. It will work on the doors , boot and ignition , but the car will NOT start.


Q: I like the switchblade key from Sharkracing. Can I use it for my car.

A: Yes and no. The switchblade key doesn't have a transponder in it. You'll be able to open the doors and boot , and turn the key in the ignition. But you won't be able start the car.
I'm thinking about doing a DIY on fitting a transponder in the switchblade in the near future.
I would not suggest using the method descriped on Sharkracing's site. It will render the whole transponder system useless.

Q: I locked my doors and the key is still in my car. What can I do ??

A: If you have the key-code , you can get a copy of the key made.
The key code for a Hyundai Coupé is a T followed by a number from 1 to 1000. T452 for example.
If you have the chassis code , the dealership will be able to look up the key code.


Q: I’ve lost all my keys , and I don’t know my chassis code. Now What ?

A: If you can get in the car and take out the door handle , a locksmith can ussually make a key out of that. Take the passenger side door handle. That one is ussually rarely used.

You’ll have to get a transponder key and have the dealership program it into the car. Problem is , you allways need to have 2 keys programmed in the ecu.

But , for people on a tuning board , it should be bloody hard not to have your chassis number memorized.


Q: What is the J on my car key ? Is it part of the code ?

A: You drive a Gen 1 or 2 , I assume. The J (or X for gen 3)is the key profile. It shows the type of transponder in the key.


Q: How do I program the key into the ecu ?

A: Here is the proper procedure:

1 Insert Programing key (bleu head) into the ignition and turn on/off 5 times
2 Remove the programming key and insert the new key
3 Turn the ignition ON. This should be done within 15 seconds after removing the master key
4 If there is more than one key to be programmed , it should also be inserted and turned to the ON position within the 15 seconds. Don't use the programming key.

All keys you own must be programmed. If the previous owner still has a key , this one will now be useless (for starting the car). The min number of keys programmed is 2 (master and user key) and the maximum is 4.


Q: Can I program new remote controls for my central locking ?

A: Yes. Heres the procedure:

1 Remove the crash pad and look for the Receiver Unit. Its a black box.
2 Switch the switch on the side to SET.
3 Press either the LOCK or UNLOCK button on all the remotes.
4 Put the switch back to OFF
5 Test all the remotes and put the crash pad back together.


If there are any further questions , just PM me , and I'll get back to you.

Wolf

Nice one. I'm sure this will prove useful in the future. Should be made into a sticky or put in the DiY section on the main site or something...

Stupid question. Does the transponder work on the principle of sending a signal down through the metal of the key or is it a wireless thing. IF so would it not be possible to use the switchblade key and leave the original on the same ring. OR if not can the transponder be taken out and placed into the switchblade. You mention you might consider a DIY effort. If you get it sussed put my name down for 1 switchblade key.

The transponder is wireless. But it doesn't have a long range. If you have spare key , without a transponder , in the ignition , and hold the original one right next to it , the car will start. But having both on the key ring , isn't enough. Trust me , I've tried. If they are close enough it works , otherwise , no luck.

I'm ordering something from sharkracing this weekend , the switchblade is part of it.

Hi, We recently puchased an F2 evo and guess what only one key , luckily its the purple headed one . I purchased a new key from local dealer and have tried the five times on and off that you describe in this post but the engine is turning over but not starting. I noticed that you said blue key so i was wondering if it is maybe a different sequence for the purple headed ones.
I also puchased a plip from ebay and the local dealer said they would need to get back to me on programing it , sofar not heard from them, if you have any ideas would appreciate hearing them as getting fed up with trying to get a spare set sorted :( :( .
Yours Marty

The F2 Evo has the alarms system in it. The immobilizer of the alarm and the stock immobilizer are 2 different things. The procedure I described is for programming the key in the stock immobilizer system. I don't have any documentation on the Cobra alarm system , because the F2 Evo was never relaesed in Belgium or the Netherlands. :bang

I'll look it up for you. I will PM you back when I've found something. But for now , I can't help you yet.

Hi Werewolf, thanx for getting back to me , I found another post about keys and someone on there said to program the f2 evo keys it is the purple headed key in and turn on six times then put new key in turn on and wait 15 seconds , i tried this and it worked :rollin :mrgreen: , so i am well pleased as now have a spare key and it only cost £35 as the dealer wanted another £45 for programing it . J ust need to get the plip working now.
Yours Benlui.

That key also doesn't have the chip in either so would not accept a programing

I was quoted £34 by a local locksmith to cut and reprogram my key (they have readers that can swop the code over). They have to be a good one not those people you find in B&Q

Reset Gen 3 Alarm


* Put your key in the ignition and turn it to ACC
* Close all doors
* Hit the lock key on your key fob
* Take the key out
* Hit the lock key again - This should arm the alarm. Don't do anything dumb to set it off!
* Immediately hit unlock
* If your alarm responds correctly, then hooray for you, ya fixed it!
* Repeat for additional fobs
